Captured live from the server via tools/list.

optionality_check_balance

Check a patron's credit balance at this operator. This is the patron's spending balance — credits purchased via Lightning for tool calls at this operator. For the operator's own balance at the Authority (needed to certify patron purchases), use authority_check_balance instead. Free — no credits required. Proof of npub ownership is required to prevent anyone-with-the-registry from enumerating balances.

Parameters2

npub	string	required	The Nostr public key (npub1...) whose balance to check.
dpop_token	string	required	Raw JSON of a kind-27235 Nostr event signed by npub — not base64, not NIP-98 'Authorization: Nostr <b64>' framing. Its `u` tag must hold THIS tool's exact name (from tools/list), not the endpoint URL; content:"", created_at within 60s of now, and a random `nonce` tag recommended. Or a cached dpop_token phrase.

optionality_restore_credits

Credit a patron's ledger from a BTCPay-settled invoice. **RESTRICTED to the operator** — the operator owns the books and is the only party who can issue a manual credit grant. Patrons who believe they paid but never got credits must escalate to the operator's support, who then invokes this tool on their behalf. Use cases: cold-start vault races during check_payment, ncred delivery hiccups, patrons closing Top-Off sheets before settle, any infrastructure incident that left an invoice settled at BTCPay but uncredited on the operator's ledger. Idempotent — if the invoice is already credited (in the patron's ``credited_invoices``), returns success with credits_granted=0.

Parameters3

invoice_id	string	required	The BTCPay invoice ID to verify and credit.
patron_npub	string	required	The patron's npub whose ledger receives the grant.
dpop_token	string	required	A kind-27235 Nostr event signed by the OPERATOR's nsec for this tool. Patron proofs are rejected.

optionality_account_statement

Generate a patron's account statement at this operator. Returns the patron's purchase history, active credit tranches, per-tool usage breakdown, and recent daily usage logs. This is the patron's spending account — not the operator's Authority tax balance. Free — no credits consumed. Proof of npub ownership is required to prevent statement-scraping of arbitrary patrons.

Parameters3

npub	string	required	The patron's Nostr public key (npub1...).
dpop_token	string	required	Raw JSON of a kind-27235 Nostr event signed by npub — not base64, not NIP-98 'Authorization: Nostr <b64>' framing.

optionality_account_statement_infographic

Generate a visual SVG infographic of your account statement. Returns the same data as account_statement, rendered as a dark-themed SVG graphic with balance hero, metrics cards, health gauge, tranche table, and tool usage breakdown. Costs 1 api_sat per call. Proof is verified by ``debit_or_deny`` before any cost is incurred.

optionality_report_issue

File a field report about this service as a GitHub issue on the operator's repo. Found a tool's metadata or response wrong or confusing? Report it where the tool lives. The **author of record is your npub** — no npub / no proof, no issue — and it is stamped into the issue so the report is attributed to you, not the operator. Costs a small fee (a free write to an issue tracker would be abused). The report is PUBLIC and goes to the maintainers' normal triage; nothing is verified here. Returns the filed issue's repo, number, and url. If this operator has not enabled field reports, returns an "issue reporting not configured" situation and you are not charged.

Parameters5

npub	string	required	Your Nostr public key (npub1...); the report's author of record.
dpop_token	string	required	Raw JSON of a kind-27235 Nostr event signed by npub — not base64, not NIP-98 'Authorization: Nostr <b64>' framing. Its `u` tag must hold THIS tool's exact name (from tools/list), not the endpoint URL; content:"", created_at within 60s of now, and a random `nonce` tag recommended. Or a cached dpop_token phrase.
title	string	required	One-line summary of the problem.
body	string	required	The details — which tool, what was wrong, what you expected.
tool_name	string	optional	Optional: the specific tool the report is about (e.g. "schwab_get_option_chain").

optionality_service_status

Check the health and configuration of this service. Free.

Parameters

No parameters.

Raw schema

{
  "type": "object",
  "properties": {},
  "additionalProperties": false
}

optionality_get_operator_onboarding_status

Report this operator's configuration readiness. Shows which operator settings are configured, which are missing, and how to deliver each missing value. For patron-level credential status, use get_patron_onboarding_status instead. Free.

Parameters

No parameters.

Raw schema

{
  "type": "object",
  "properties": {},
  "additionalProperties": false
}

optionality_get_patron_onboarding_status

Report a patron's credential readiness for this operator. For set-once services (eXcalibur, TheBrain), shows which patron secrets are configured and which are missing. For dynamic/OAuth2 services (Schwab), reports that no patron credentials are needed. Free. Proof of npub ownership is required because credential presence is sensitive information about the patron's setup.

Parameters2

patron_npub	string	required	The patron's Nostr public key (npub1...).
dpop_token	string	required	A kind-27235 Nostr event signed by patron_npub for this tool.

    }
  },
  "required": [
    "patron_npub",
    "dpop_token"
  ],
  "additionalProperties": false
}

optionality_session_status

Check operator readiness. Returns the operator lifecycle state and clear guidance on what to do next. Free. Lifecycle states: - ready: Operator is warm and fully operational — vault AND pricing model verified. Proceed with tool calls. - warming_up: Operator is initializing (cold start). Try a tool call — it will warm up on demand. - misconfigured: Persistence rejected a query with a permanent SQL error (permission denied, missing relation). Paid tools will fail until the operator repairs the database — retrying does not help. - quota_exceeded: The persistence provider (Neon) answered HTTP 402 — the operator's database has exhausted its compute/storage quota, so the books are locked for billing. Paid tools fail; retrying does NOT help. The operator's Authority must restore capacity (upgrade the plan or wait for the quota reset). Free tools remain available. - not_registered: Operator has no Authority relationship yet. Call register_operator first. - no_identity: Operator nsec is not configured. Deployment issue.

Parameters1

patron_npub

string

optional

Optional. If supplied, the response includes an ``upstream_oauth`` block with the patron's stored OAuth token expiry (runtime-derived from vault state) so a client can refresh proactively rather than reactively after a stale-token failure.

Raw schema

{
  "type": "object",

    }
  },
  "additionalProperties": false
}

optionality_request_credential_channel

Open a Secure Courier channel for credential delivery. This is the CREDENTIAL-DELIVERY flow — use it to hand over a service secret (API keys, tokens). To merely prove you control an npub (the usual answer to a ``proof_required`` error), use ``request_npub_proof`` instead. Note: dynamic/OAuth2 services (e.g. Schwab) need NO couriered secret — check ``service_status`` first. Sends a welcome DM with a credential template. The recipient must read the DM in their Nostr client, fill in the fields, and reply manually. **This is a human-in-the-loop flow.** After calling this tool, STOP and tell the user what to do. Wait for the user to confirm they have replied before calling ``receive_credentials``. Do NOT poll or retry — each ``receive_credentials`` call destructively drains the relay mailbox.

Parameters2

sender_npub	string	optional	Required. The npub to send the template to.
service	string	optional	Required. The credential service name (e.g., from get_operator_onboarding_status or get_patron_onboarding_status).

Raw schema

{
  "type": "object",
  "properties": {
    "sender_npub": {

    "service": {
      "default": "",
      "type": "string",
      "description": "Required. The credential service name (e.g.,\nfrom get_operator_onboarding_status or get_patron_onboarding_status)."
    }
  },
  "additionalProperties": false
}

optionality_receive_credentials

Pick up credentials from the Secure Courier. Completes the CREDENTIAL-DELIVERY flow (the ownership-proof counterpart is ``receive_npub_proof``). **Call this only after the user confirms they have replied.** Deterministic, one-shot retrieval: name the response you want with ``(sender_npub, service, dpop_token)`` and the tool drains ONLY the rendezvous relay that channel was pinned to. Every popped DM with the wrong session phrase is deleted and its sender is NACK'd; the first DM with the matching phrase is accepted (ACK'd) and the scan stops. If none match, the queue is drained and a ``courier_not_found`` result is returned. Do NOT poll, loop, or retry. If a credential_card (ncred1...) is provided, it is redeemed directly without any relay access (dpop_token not required for that path). On success, the payment processor client is reinitialized from the new credentials — no server restart needed.

Parameters4

sender_npub	string	optional	Required. The npub that sent the credentials.
service	string	optional	Required. The credential service name (must match the service used in request_credential_channel).
dpop_token	string	optional	Required. The session phrase returned by request_credential_channel for this exact channel.
credential_card	string	optional	Optional. An ncred1... card to redeem directly (bypasses the relay drain; dpop_token not needed).

optionality_forget_credentials

Delete vaulted credentials for a specific service and npub. For operator credentials, pass the operator's own npub. For patron credentials, pass the patron's npub. Always requires proof of npub ownership — a deletion is as destructive as a write.

Parameters3

service	string	required	The credential service to forget.
npub	string	required	The Nostr public key (npub1...) whose credentials to forget.
dpop_token	string	required	Raw JSON of a kind-27235 Nostr event signed by npub — not base64, not NIP-98 'Authorization: Nostr <b64>' framing.

optionality_update_patron_credential

Add or update a single patron credential field. Merges into existing stored credentials without affecting other fields. Useful for setting an account identifier after OAuth, changing a default brain, etc. Free. Proof of npub ownership is required — this is a write to the patron's sensitive credential vault.

Parameters4

optionality_update_operator_credential

Add or update a single operator secret field. Merges into the operator's stored credentials without touching the others — the field-level counterpart to re-delivering the whole bundle over Secure Courier. Use it to rotate one secret (a reissued ``btcpay_api_key``, say) without restating the six you did not change, where any field omitted from a courier reply is destroyed. The value is never echoed back. RESTRICTED to the operator — requires proof (nsec-signed kind-27235 or a cached dpop_token phrase); patron proofs are rejected.

Parameters3

field	string	required	The operator credential field to set. Must be declared in the operator's credential template.
value	string	required	The value to store.
dpop_token	string	required	Operator proof for this tool.

Remove a single patron credential field. Deletes one field from stored credentials without affecting other fields. Free. Proof of npub ownership is required — this is a write to the patron's sensitive credential vault.

Parameters3

npub	string	required	The patron's Nostr public key (npub1...).
dpop_token	string	required	Raw JSON of a kind-27235 Nostr event signed by npub — not base64, not NIP-98 'Authorization: Nostr <b64>' framing. Its `u` tag must hold THIS tool's exact name (from tools/list), not the endpoint URL; content:"", created_at within 60s of now, and a random `nonce` tag recommended. Or a cached dpop_token phrase.
field	string	required	The credential field name to remove.

optionality_delete_operator_credential

Remove a single operator secret field. Deletes one key from the operator's encrypted credential blob without touching the others — the field-level counterpart to ``forget_credentials``, which wipes the whole row. Use it to retire a leftover after an SDK cutover (a Prefect key after Modal, or a stored but untemplated orphan like ``anthropic_api_key``) without taking the operator down for a full re-delivery. Stored-but-untemplated fields are first-class: the delete is keyed on what is vaulted, not on what the current template declares. Idempotent — already-absent fields report ``removed: false`` without rewriting the vault. RESTRICTED to the operator — requires proof (nsec-signed kind-27235 or a cached dpop_token phrase); patron proofs are rejected. A deletion is as destructive as a write.

Parameters2

field	string	required	The operator credential field to remove (templated or not).
dpop_token	string	required	Operator proof for this tool.

optionality_get_patron_credential_fields

List stored patron credential field names (not values). Returns the names of fields stored for a patron, plus each field's ``delivered_at`` ISO-8601 timestamp when known (null for secrets vaulted before timestamps were recorded). Values are never exposed — use this to verify which fields are configured and how old each one is. Free. Proof of npub ownership is required: the list of configured fields is itself sensitive (reveals which integrations a patron has set up).

Parameters2

npub	string	required	The patron's Nostr public key (npub1...).
dpop_token	string	required	Raw JSON of a kind-27235 Nostr event signed by npub — not base64, not NIP-98 'Authorization: Nostr <b64>' framing.

optionality_request_npub_proof

Request npub ownership proof from a patron via Nostr DM. This is the npub-OWNERSHIP-PROOF flow — use it when a call returns ``proof_required``. It proves the caller controls an npub; it does NOT deliver any service secret. To hand an operator its API keys or OAuth secrets, use ``request_credential_channel`` instead. Sends a challenge DM that the patron must sign and reply to using their Nostr client. **This is a human-in-the-loop flow.** After calling this tool, STOP and tell the user to check their Nostr client and reply to the challenge. Wait for the user to confirm they have replied before calling ``receive_npub_proof``. Do NOT poll or retry — each ``receive_npub_proof`` call destructively drains the relay mailbox. **Returns** a ``dpop_token`` — the demonstrated-proof-of-possession token that the calling application MUST remember and pass as the ``dpop_token`` parameter on every subsequent paid tool call. The MCP does not retain this value across restarts. **Lifecycle:** The cached proof expires after the patron's chosen duration. When it expires, call ``request_npub_proof`` again for a fresh challenge, then wait for the user, then call ``receive_npub_proof``. Free.

Parameters3

patron_npub	string	optional	Required. The patron's npub to request proof from.
reason	string	optional	Optional. A human-readable purpose for the request ("I'm working on your request XYZ and need the Operator to do ABC for you"). Signed into the provenance attestation and shown in the DM, so the recipient sees why they are being asked — especially useful when the signer is unknown to them.
verify_at	string	optional	Optional. A free-form statement of WHERE you (the initiating agent) already showed this proof's one-time code to the user — a URL, or "your Claude.ai conversation", "the Grok session". The OAuth 2.0 Device Grant ``verification_uri``, generalized: the user approves only if the code in the DM matches the one you displayed there, so an unsolicited request they've never seen is refused. Signed into the attestation.

  "additionalProperties": false
}

optionality_receive_npub_proof

Receive npub ownership confirmation from a patron. Completes the npub-OWNERSHIP-PROOF flow (the credential-delivery counterpart is ``receive_credentials``). **Call this only after the user confirms they have replied.** Deterministic, one-shot retrieval: name the response with ``(patron_npub, dpop_token)`` — the ``dpop_token`` being the value returned by ``request_npub_proof``. The tool drains ONLY the pinned rendezvous relay that challenge was published on, stopping at the DM whose phrase matches. Mismatched DMs are deleted and NACK'd (without revealing the expected phrase). If called before the user replies, their message will never be found. Do NOT poll, loop, or retry. The signed DM itself proves npub ownership (the patron's nsec signed it). On success, returns the ``dpop_token`` — the same token. The calling application MUST remember it and pass it as the ``dpop_token`` parameter on every subsequent paid tool call. The proof (a hash of the token) is stored in the vault keyed by that hash — the MCP never stores the raw token itself. Free.

Parameters2

patron_npub	string	optional	Required. The patron's npub to receive proof from.
dpop_token	string	optional	Required. The dpop_token returned by request_npub_proof.

  },

}

optionality_check_proof_status

Check whether a previously-cached dpop_token is still valid. Mirrors ``check_oauth_status`` for the npub-proof flow: a calling agent can ask "will my next paid call accept this dpop_token?" before burning credits on a guaranteed failure. Free, no side effects — does not evict the cache or touch relays.

Parameters2

patron_npub	string	optional	Required. The patron's npub (npub1...).

  "properties": {},
  "additionalProperties": false
}

optionality_check_authority_balance

Check this operator's tax balance at the Authority. Returns the sats available for certifying patron credit purchases. When this balance reaches zero, patron top-ups cannot be certified and the operator must call purchase_credits on the Authority. This is the operator's own funding — not a patron balance. Free.

Parameters

No parameters.

Raw schema

  "type": "object",
  "properties": {},

optionality_get_pricing_model

Get the active pricing model for this operator. Free. If no model exists, self-initializes a scaffold with all registered tools at 0 sats. No economic data from code.

Parameters

Raw schema

{
  "type": "object",
  "properties": {},

optionality_set_pricing_model

Set the active pricing model. RESTRICTED to operator. Requires a valid proof (Schnorr-signed kind-27235 event) proving the caller holds the operator's nsec.

Parameters2

  ],
  "additionalProperties": false
}

optionality_reset_pricing_model

Erase all pricing models and restore a viable default. Deletes every stored model, then self-initializes a fresh one from the tool registry — all tools at 0 sats with proper UUIDs. Returns the new model. RESTRICTED to operator — requires proof (nsec-signed).

Parameters1

dpop_token

string

optional

Raw schema

{
  "type": "object",
  "properties": {

  "additionalProperties": false
}

optionality_request_adoption

Ask a chosen Authority to adopt this operator (deferred courtship). RESTRICTED to the operator — requires proof the caller controls this operator's npub. Resolves the Authority's MCP endpoint from the community registry, mints an inline ownership proof with this operator's nsec, and delivers the request MCP-to-MCP. The Authority records it as pending; its owner approves on their own time. Poll ``adoption_status`` for progress; the operator flips to ``ready`` once the Authority provisions it.

Parameters4

authority_npub	string	required	npub of the Authority to request adoption from.
dpop_token	string	optional	operator-npub ownership proof (inline kind-27235 or cached token).
service_url	string	optional	this operator's MCP endpoint (advertised to the Authority).
note	string	optional	optional message for the Authority owner.

optionality_adoption_status

Check this operator's adoption-request status at a chosen Authority. Free. Polls the Authority MCP-to-MCP for the status of this operator's request (pending / approved / rejected / provisioned).

dpop_token	string	optional

    }
  },
  "required": [
    "authority_npub"
  ],
  "additionalProperties": false
}

optionality_restore_neon_schema

Re-run ``ensure_schema()`` on every NeonVault this operator uses. Diagnostic / recovery tool for the case where the Neon HTTP SQL API is returning persistent 4xx errors and the operator suspects the schema isn't there or grants are wrong. Idempotent — uses ``CREATE TABLE IF NOT EXISTS`` so a successful re-run is harmless. Returns the per-step result. If any step raises, surfaces the Neon error message inline (0.31.0 reads the SQL error body that earlier wheels swallowed behind ``raise_for_status``). RESTRICTED to operator — requires proof (nsec-signed).

Parameters1

dpop_token

string

optional

Raw schema

{
  "type": "object",
  "properties": {
    "dpop_token": {
      "default": "",
      "type": "string"
    }
  },
  "additionalProperties": false
}

optionality_list_canonical_identities

Return canonical (tool_id, mcp_name, …) for every tool the wheel exposes. The authoritative source for any client (Studio, agents, FE) that needs to know how this MCP identifies its tools. Reconcile uses this output to UUID-join against the stored pricing model — no name-based UUID derivation, no guessing. Includes both ToolIdentity-seeded tools and any UUID recorded by ``@paid_tool`` that is missing from the registry. The latter appear with ``registered: false`` (and in the top-level ``unregistered`` array) so Reconcile can flag deploy drift instead of silently reporting clean when a live tool was never seeded (#174). If the operator renames a function or rebrands a slug, the mcp_name in this output changes but tool_id stays. That's the whole point of the canonical-UUID design. Also diffs the live FastMCP wire surface against the registry. Tools exposed on the wire but absent from the registry appear in ``unregistered`` so Reconcile can flag deploy drift instead of silently under-reporting (issue #175). Free, no side effects.

Parameters

No parameters.

Raw schema

  "type": "object",
  "properties": {},
  "additionalProperties": false

optionality_get_nostr_profile

Read an npub's public Nostr profile (NIP-01 kind-0 metadata). Free, no proof — the data is already public on relays. Returns the latest metadata fields (name, display_name, about, picture, banner, nip05, website, lud16) or an empty profile if none is published.

Parameters1

npub

string

optional

Raw schema

{
  "type": "object",
  "properties": {
    "npub": {
      "default": "",
      "type": "string"
    }
  },
  "additionalProperties": false
}

optionality_publish_nostr_profile

Publish a CLIENT-SIGNED kind-0 profile to relays for an npub. The wheel never holds a patron nsec. The frontend signs the kind-0 metadata event with the patron's session key or a NIP-07 extension and passes the signed event (JSON) here; the wheel verifies the signature matches the npub, then relays it to public relays. The signature is the authorization — no proof token, no key custody. Free.

Parameters2

npub	string	optional	The patron's Nostr public key the event must be signed by.
signed_event	string	optional	A JSON-encoded, client-signed kind-0 event.

  },
  "additionalProperties": false
}

optionality_check_price

Preview the effective cost of a tool call. Shows the base cost and any constraint effects (discounts, free trials, surge pricing). Free — no credits required.

Parameters4

tool_id	string	required	Either the tool's UUID (from the pricing model) or a bare capability string (e.g. ``"deal_scenario"``). FE callers usually have the capability name; this resolves both so the FE doesn't need to derive UUIDs locally.
npub	string	optional
dpop_token	string	optional
tool_kwargs	string	optional	Optional JSON object with tool call parameters for ad valorem / categorical-multiplier pricing preview (e.g. '{"amount_sats": 5000}' or '{"difficulty": "sovereign", "mode": "live"}').

optionality_list_coupons

List every coupon this operator has minted (newest first). Each row carries the current ``times_redeemed`` counter — the Studio renders a progress bar from this against ``total_uses``. RESTRICTED to operator — requires proof.

  "additionalProperties": false
}

optionality_update_coupon

Patch a coupon's editable fields. Pass only the fields you want to change. To set a cap to unlimited (NULL in the schema), pass ``clear_uses_per_patron=true`` or ``clear_total_uses=true``. Renaming the code is allowed — existing patron redemption rows survive (they key on coupon id). RESTRICTED to operator — requires proof.

optionality_delete_coupon

Delete a coupon. Cascades to all patron redemptions. Any chain step referencing the deleted coupon_id becomes a no-op (the constraint returns neutral on unknown ids) — the Studio surfaces orphan references as warnings. RESTRICTED to operator — requires proof.

Parameters2

coupon_id	string	required
dpop_token	string	optional

Raw schema

{
  "type": "object",
  "properties": {
    "coupon_id": {
      "type": "string"
    },
    "dpop_token": {
      "default": "",
      "type": "string"
    }
  },
  "required": [
    "coupon_id"
  ],
  "additionalProperties": false
}

optionality_redeem_coupon

Claim a coupon by its name (the code the operator shared). Looks up the operator's coupon by ``code``, validates the window and total cap, and records a per-patron redemption row. Subsequent paid tool calls on this MCP auto-apply the discount until ``uses_per_patron`` is exhausted. Free — no credits required. Requires proof of ``npub``. Idempotent: redeeming the same code twice returns the existing redemption.

Parameters3

npub	string	required
code	string	required
dpop_token	string	optional

Raw schema

{
  "type": "object",
  "properties": {
    "npub": {
      "type": "string"

    "dpop_token": {

      "type": "string"
    }
  },
  "required": [
    "npub",
    "code"
  ],
  "additionalProperties": false
}

optionality_list_my_coupons

List the coupons this patron has redeemed on this operator. Returns both active and exhausted redemptions with a per-row ``status`` (``active`` / ``window_closed`` / ``patron_limit`` / ``total_limit``). Free — requires proof of ``npub``.

Parameters2

npub	string	required
dpop_token	string	optional

Raw schema

{
  "type": "object",
  "properties": {
    "npub": {
      "type": "string"

      "type": "string"
    }
  },
  "required": [
    "npub"
  ],
  "additionalProperties": false
}

optionality_forget_coupon

Remove a coupon from this patron's redemption list. Cosmetic only — the coupon itself still exists at the operator, and the patron can re-redeem the same code later while the window allows. Free — requires proof of ``npub``.

Parameters3

npub	string	required
coupon_id	string	required
dpop_token	string	optional

Raw schema

{
  "type": "object",
  "properties": {

optionality_notarize_ledger

Build a Merkle tree of all patron balances and submit the root to Bitcoin via OpenTimestamps. Operator-only background task. Bitcoin confirmation takes 1-6 hours. Free — no credits required.

Parameters

No parameters.

Raw schema

optionality_get_notarization_proof

Generate a Merkle inclusion proof that a patron's balance was included in a Bitcoin-notarized snapshot.

Parameters2

notarization_id	string	required	The notarization record ID.
npub	string	required	The patron's Nostr public key (npub1...).

Raw schema

{
  "type": "object",
  "properties": {
    "notarization_id": {

}

optionality_list_notarizations

List recent Bitcoin notarization records.

Parameters2

limit	integer	optional	Maximum records to return (default 20).
status	string	optional	Optional filter (e.g., 'submitted', 'confirmed').

  "type": "object",

      "description": "Optional filter (e.g., 'submitted', 'confirmed')."
    }
  },
  "additionalProperties": false
}

optionality_deal_scenario

Generate a fresh options trading scenario and open a journal entry.

Parameters7

mode	string	required	``historical`` \| ``fiction`` \| ``live`` — controls how the Firm grounds the scenario. ``live`` uses the provider's web_search tool and costs more tokens.
difficulty	string	required	``apprentice`` \| ``journeyman`` \| ``adept`` \| ``sovereign`` for a fresh opportunity; ``mulligan`` only paired with replay_entry_id.
npub	string	optional	Required. Your Nostr public key (npub1...) for credit billing.
dpop_token	string	optional
max_loss_usd	any	optional	Optional per-trade risk envelope in USD. When set, the Firm sizes the constraints (account size, sizing limits) so a thoughtful structure can fit the budget. Useful for trainees who reason better about $250 than $10,000 versions of the same trade.
replay_entry_id	any	optional	Optional id of an evaluated journal entry. When set, the wheel reissues that entry's scenario as a new play, forcing mode="historical" and difficulty="mulligan". Skips the LLM call — no new generation cost, just the operator's toll per the pricing model. The new play is journaled as its own entry; the original is untouched.
sector	string	optional	Optional market-sector hint (e.g., ``"biotech"``, ``"semis"``, ``"banks"``). When set, the Firm picks the underlying ticker from that sector and tailors catalysts / relevant_facts / red_herrings to its dynamics. Empty string = no constraint, Firm picks freely. Ignored on replays (the original scenario's ticker is reused).

optionality_fetch_scenario

Redeem a deal_scenario claim check. Free. While ``status`` is ``running``, wait ``poll_after_seconds`` and call again. When ``done``, ``result`` holds the deal_scenario response (``entry_id`` + ``scenario``). ``expired`` means the claim is unknown or its result aged out — start a new deal_scenario request.

Parameters3

claim_check	string	required
npub	string	optional	Required. Your Nostr public key (npub1...) for credit billing.
dpop_token	string	optional

  },
  "required": [
    "claim_check"

  "additionalProperties": false
}

optionality_ask_tip

Get a non-spoiler Socratic hint for an open journal entry. history is an optional JSON-encoded array of prior {question, answer} turns from this clue conversation, so follow-on questions have context. The wheel caps it hard, so oversupplying gains nothing. Returns a **claim check**, not the hint. Redeem the ``claim_check`` with ``optionality_fetch_tip``, polling until ``status`` is ``done``. A degenerate question (empty or oversized) needs no LLM, so it returns a settled ``{status: "done"}`` nudge directly instead of a claim to poll.

Parameters5

optionality_fetch_tip

Redeem an ask_tip claim check. Free. While ``status`` is ``running``, wait ``poll_after_seconds`` and call again. When ``done``, ``result`` holds the ask_tip response (``tip``). ``expired`` means the claim is unknown or its result aged out — ask again.

optionality_judge_trade

Evaluate the trainee's trade. Persists evaluation, parses legs, recomputes leaderboard. Returns a **claim check**, not the evaluation. Redeem the ``claim_check`` with ``optionality_fetch_judgement``, polling until ``status`` is ``done``.

optionality_list_journal

Server-side sorted, grouped, paginated list of the caller's journal. Sorting and grouping are done in SQL, so each page is a slice of the fully-ordered dataset. Returns ``{total, page, page_size, groups, entries}``; ``groups`` carries per-group counts over the whole set.

optionality_get_shared_entries

List a target patron's shared evaluated entries — newest first. Public, free read: anyone (including guests) can browse the trades a leaderboard peer has chosen to share. Eager-loads the evaluation and trade proposal so the FE can render the full assessment with no follow-up call. No npub/proof envelope — this is a bootstrap-style tool the FE invokes without identity injection.

optionality_escrow_nsec

Deposit a freshly-generated nsec for operator-managed Nostr signing. Trade-off: sovereignty for UX. Optionality holds the nsec encrypted in Neon (AES-256-GCM, key derived from operator nsec). Until you withdraw it, the operator can sign Nostr DMs on your behalf. Use this only for fresh game-persona keypairs — never for an existing Nostr identity that lives elsewhere. The nsec MUST derive to the same npub that authenticated this call, or the deposit is rejected.

Parameters3

nsec	string	required
npub	string	optional	Required. Your Nostr public key (npub1...) for credit billing.
dpop_token	string	optional

Raw schema

{
  "type": "object",
  "properties": {
    "nsec": {
      "type": "string"
    },
    "npub": {
      "default": "",
      "description": "Required. Your Nostr public key (npub1...) for credit billing.",
      "type": "string"
    },
    "dpop_token": {
      "default": "",
      "type": "string"
    }
  },
  "required": [
    "nsec"
  ],
  "additionalProperties": false
}

optionality_withdraw_nsec

Return the plaintext nsec once and remove it from operator storage. Required acknowledgment string (exact match): "I understand I am now solely responsible for this nsec." After this call you regain full self-custody; the operator forgets the key. You're now responsible for stashing it in a Nostr client (0xchat, Damus, Amber) and signing DMs locally via NIP-07.

Parameters3

acknowledgment	string	required
npub	string	optional	Required. Your Nostr public key (npub1...) for credit billing.
dpop_token	string	optional

Raw schema

{
  "type": "object",
  "properties": {
    "acknowledgment": {
      "type": "string"

      "description": "Required. Your Nostr public key (npub1...) for credit billing.",
      "type": "string"
    },
    "dpop_token": {
      "default": "",
      "type": "string"
    }
  },
  "required": [
    "acknowledgment"
  ],
  "additionalProperties": false
}

optionality_send_patron_dm

Sign and publish a Nostr DM as the patron, using the escrowed nsec. The patron's escrowed nsec is loaded, decrypted in-process, used to sign a kind-4 NIP-04 DM + a kind-1059 NIP-17 gift wrap, broadcast via the operator's relay pool, then the plaintext drops out of scope. The DM's `pubkey` is the patron's own — recipients see it as authored by the patron, not relayed. Returns {"success": True, "sender_npub", "target_npub"} on the happy path; {"success": False, "error"} on validation or send failure.

Parameters4

target_npub	string	required
message	string	required
npub	string	optional	Required. Your Nostr public key (npub1...) for credit billing.
dpop_token	string	optional

Raw schema

{
  "type": "object",
  "properties": {
    "target_npub": {
      "type": "string"
    },
    "message": {
      "type": "string"
    },
    "npub": {
      "default": "",
      "description": "Required. Your Nostr public key (npub1...) for credit billing.",
      "type": "string"
    },
    "dpop_token": {
      "default": "",
      "type": "string"
    }
  },
  "required": [
    "target_npub",
    "message"
  ],
  "additionalProperties": false
}

optionality_get_escrow_status

Return ``{"escrowed": bool}`` — whether Optionality holds the patron's nsec. Free; the FE polls this to render Withdraw vs Deposit affordances on the Profile page.

Parameters2

npub	string	optional	Required. Your Nostr public key (npub1...) for credit billing.
dpop_token	string	optional

Raw schema

{
  "type": "object",
  "properties": {
    "npub": {

      "type": "string"
    },
    "dpop_token": {
      "default": "",
      "type": "string"
    }
  },
  "additionalProperties": false
}

optionality_get_api_usage_stats

Aggregated LLM usage and cost for this patron's calls. Returns ``{"models": [{"model", "runs", "total_calls", "total_input_tokens", "total_output_tokens", "total_cost_usd", "priced_runs"}, ...], "totals": {...}}``. One row per distinct model the patron's tool calls have invoked. ``total_cost_usd`` is what the PROVIDER reported for those calls, not a figure reconstructed from a price table — tokens from two models are not comparable money, so a local table goes wrong the moment the route changes model. ``priced_runs`` says how many of ``runs`` carried a reported cost, so a caller can render "$0.42 across 3 of 5 runs" rather than implying the rest were free. ``totals.avg_cost_usd`` is what one call actually costs to serve — the number that says whether a tool's sats price covers its own compute.

Parameters2

npub	string	optional	Required. Your Nostr public key (npub1...) for credit billing.
dpop_token	string	optional

Raw schema

{
  "type": "object",
  "properties": {
    "npub": {

optionality-mcp

MCP server and React drill UI for an AI-judged options trading practice game. Built on FastMCP.

Optionality is an instance of a Tollbooth-DPYC™ service: engagement is monetized with convenient Don't Pester Your Customer™ (DPYC™) Bitcoin commerce. Patrons pre-fund a balance over Lightning and play without per-request payment ceremonies. All prices are dynamic and set by the operator — the Welcome page shows live quotes. Patrons can also enter Tollbooth-DPYC coupons to take advantage of discounts when they are offered.

How a Round Works

The Dealer deals. A dealer LLM composes a complete options scenario: ticker, spot, IV regime and skew, macro backdrop, catalyst, key levels, and constraints — optionally including a max-loss budget the structure must fit.
You pitch. Free text, the way you'd pitch a senior PM. Multi-leg structures, single legs, or a deliberate stand-aside — declining to trade is a legitimate, gradeable answer.
The Judge grades. A judge LLM parses your pitch into structured legs, scores it across six dimensions, and proposes an alternative structure you can overlay on the risk chart.

Six judging dimensions: Strategy Selection, Strikes & Tenor, Risk/Reward, Macro Integration, Tail Risk, and Communication — each 0–20, rolled into a 0–100 score with letter grades A+ through F.

Core Pedagogy — Red Herrings

Each scenario embeds 1–2 facts that are factually TRUE but immaterial, woven inline into the narrative and never flagged. Citing them as trade drivers penalizes the trainee; recognizing them as noise and setting them aside earns points. The drill is signal-from-noise on a tape where everything you read is true.

A Facts Ledger accompanies every evaluation: which scenario facts you integrated, which you missed, which red herrings you caught, and which you followed.

Scenario Modes & Difficulty

Three historicity modes:

Historical Fiction — real, identifiable market moments (SVB week, the gilt crisis), grounded in the actual macro and IV regime of the day
Fiction — invented regimes: counterfactual shocks, de-peg cascades, gamma squeezes
Live Events — web-search-grounded scenarios anchored to this week's actual tape, with cited sources

Four difficulty personas: Apprentice, Journeyman, Adept, Sovereign. Leaderboard points are difficulty-weighted, so rankings can't be padded on easy mode. A Mulligan mode replays an already-judged scenario fresh.

Options Math — One Source of Truth

The server builds the full option chain from the dealer's scaffold — three expirations, a strike ladder around spot, a three-anchor IV smile honoring put-bid skew — and prices it with Black–Scholes. The same math runs client-side, so the trainee, the charts, and the judge all see identical numbers.

Option chain modal in broker convention: calls left, strikes and smile center, puts right; tap a mid to buy or sell; running net-premium readout
Risk profile chart with expiration P/L, breakeven markers, and a DTE slider that replays theta bleed across the holding period
Judge-alternative overlay to compare your payoff curve against the structure the judge would have run

Socratic Clue Desk

Mid-scenario, ask anything. Educational questions get direct, formula-backed answers; tactical questions get redirected to the dimension worth more thought — the responsibility stays with the trainee. The desk never reveals the scenario's hidden facts or red herrings. Clues carry a scoring penalty.

Journal, Leaderboard & Peer Learning

Journal — every round persisted: open drafts, submitted pitches, full evaluations with leg tables and charts
Leaderboard — six sort orders (weighted average, weighted best, raw average, raw best, streak, played), filterable by mode and difficulty
Streaks — consecutive scores of 70+, current and all-time
Shared entries — opt in to share an evaluated round so others can study the pitch, the grade, and the ledger
Profile — display name, avatar, bio
Usage — transparency tab showing per-model token consumption, per-tool spend, and the patron's account statement

Repo Layout

code

optionality-mcp/

Heavy LLM tools (deal, judge, clue desk) use a claim-check async pattern: the call returns a claim immediately and the client polls a free fetch tool, so slow generations survive client timeouts.
