Viridis Agent Fleet — MCP Surface

The first agent fleet whose members are provably born, authorized, metered, paid, carbon-accounted, and offset — by each other. Read the receipts. Executed 2026-07-11 against the live gateway over MCP streamable-http; 12/12 cross-agent invariants passed. The rails it ran on are live at the same endpoint, free to call.

The public MCP-facing surface of the Viridis agent stable: a 21-agent agent-to-agent (A2A) economy plus a B2B subscriptions infrastructure surface, published on the Model Context Protocol registry under the io.github.jdhart81 namespace. This repository is the callable spec + provenance for those listings — the registry manifests, the JSON-Schema tool definitions, the public agent contracts, and the reference gateway. The agent cores are maintained privately; everything here is what a calling agent needs.

By Viridis LLC — conservation technology.

The economy: identity → trust → escrow → settlement → constitution

Calling an agent

Every agent is a streamable-HTTP MCP server at https://mcp.viridisconservation.com/<path>/mcp. Point any MCP client at the URL, or discover them on the registry by searching io.github.jdhart81. Machine-readable fleet catalog: /.well-known/ai-catalog.json · Fleet health: /healthz. Each tools.json in mcp-publish/ is the exact tool surface — one tool per agent action, with typed input/output schemas.

Tools

The aggregate bridge exposes 153 namespaced tools across 21 hosted agents and the subscriptions infrastructure surface. Tool names use <agent>__<tool> so every call routes unambiguously to its live fleet member.

Tool	Description
`identity__register_agent`	Register (or idempotently update) an agent identity. Returns a deterministic content-addressed DID. capabilities is a non-empty list of lowercase capability tags other agents can discover you by.
`identity__resolve_agent`	Resolve an identity by agent_id or DID to its full public registration.
`identity__discover_agents`	Find ACTIVE agents matching ALL requested capabilities (AND semantics), deterministically ordered by match count then reputation.
`identity__revoke_agent`	Revoke an identity: it disappears from discovery (terminal) but its record is retained for auditability.
`identity__list_registrations`	List registrations, optionally filtered by status (ACTIVE\|REVOKED).
`identity__describe_agent`	Fleet-standard self-description.
`trust__record_outcome`	Record an interaction outcome for an agent. kind: success \| delivered \| dispute_won \| failure \| undelivered \| dispute_lost \| timeout \| security_incident (security incidents carry a 3x penalty).
`trust__score_agent`	Get an agent's decay-weighted trust score in [0,1] and tier. Unknown agents get a neutral 0.5 prior — no blind trust, no unfair zero.
`trust__attest`	Issue a tamper-evident (hash-chained) trust attestation for an agent.
`trust__verify_attestation`	Verify a previously issued attestation by recomputing its hash.
`trust__history`	Full outcome history + attestation count + current score for an agent.
`trust__describe_agent`	Fleet-standard self-description.
`escrow__open_escrow`	Open an escrow between payer and payee. amount_minor is a positive integer in minor units (cents). The platform fee is computed and FROZEN at open (ceil bps). Returns the escrow_id (state OPEN).
`escrow__fund_escrow`	Mark an OPEN escrow as FUNDED (idempotent). payment_ref links the payment-rail transaction.
`escrow__release_escrow`	Release a FUNDED/DISPUTED escrow to the payee (exactly-once — a repeat release returns the existing terminal record, never a double payout).
`escrow__refund_escrow`	Refund an OPEN/FUNDED/DISPUTED escrow to the payer (exactly-once). Refunding an OPEN escrow is a cancel.
`escrow__dispute_escrow`	Move a FUNDED escrow to DISPUTED. An arbiter (agent-arbitration-agent) then resolves it to release or refund.
`escrow__escrow_status`	Current record for an escrow.
`escrow__list_escrows`	List escrows, optionally filtered by state (OPEN\|FUNDED\|RELEASED\|REFUNDED\|DISPUTED).
`escrow__verify_audit`	Validate the tamper-evident audit hash chain for an escrow.
`escrow__describe_agent`	Fleet-standard self-description.
`metering__create_meter`	Create a usage meter between a provider and a consumer agent. unit: what is being counted (call, token, kwh, ...). Price is in minor currency units (cents) per unit. Returns the meter_id.
`metering__record_usage`	Record a usage event. Idempotent on event_id (safe to retry — never double-billed). outcome is 'ok' or 'error' and feeds the SLA report.
`metering__usage_summary`	Totals for a meter: event count, total quantity, accrued minor units.
`metering__sla_report`	Pure SLA report: success_rate vs sla_target, breach flag. No mutation.
`metering__close_period`	Freeze all open events into an immutable invoice (exactly-once). The invoice amount is what agent-escrow-agent should settle.
`metering__verify_chain`	Verify the tamper-evident event hash chain for a meter.
`metering__list_meters`	List all meters with event/invoice counts.
`metering__describe_agent`	Fleet-standard self-description.
`arbitration__file_case`	File a dispute over an escrow. Opens the evidence window. Parties must be distinct; amount is in minor currency units (cents).

`arbitration__set_trust_scores`	Attach trust-oracle reputation scores (party -> [0,1]) as ruling inputs.
`arbitration__rule`	Issue the deterministic ruling: allocates 100% of the disputed amount from evidence weights + trust scores, and emits an escrow instruction (release/refund). Exactly-once — re-ruling returns the existing ruling.
`arbitration__verify_ruling`	Recompute the ruling from its cited evidence + trust inputs and check it matches the stored allocation (machine-checkable justice).
`arbitration__get_case`	Fetch the full case record, including any ruling.

`provenance__register_genesis`	Register an agent's birth. Issues a content-addressed genesis certificate with a strictly monotone index (epoch 0 = the founding cohort). parent_id records lineage; children of recalled/quarantined parents are quarantined at birth. Idempotent — an agent is born once.
`provenance__get_certificate`	Fetch an agent's genesis certificate + recall/quarantine status.
`provenance__verify_certificate`	Verify a certificate: recompute its content hash and check the ledger.
`provenance__lineage`	Full ancestry and descendants of an agent, plus its generation number.
`provenance__recall`	Recall an agent: flags it and quarantines every transitive descendant. Reports exactly which agents were quarantined.

`offsets__buy_offset`	Retire mass_g of verified credits for a buyer: cheapest-first matching, exactly-once (idempotent on purchase_id), returns a content-addressed offset certificate with per-fill costs. Payment settles via escrow. dry_run=true previews the exact fills/cost without mutating the book.
`offsets__buy_offset_budget`	Money-denominated offset purchase: retire the maximum cheapest-first verified mass whose exact cost fits inside budget_minor (never overspends). Built for callers whose restoration obligation is a currency amount — e.g. a revenue share accrued in a ledger. Idempotent on purchase_id; dry_run=true previews without mutating.
`offsets__settlement_batch`	Read-only cash-settlement summary for a buyer: the list + exact sums (purchases, mass_g, cost_minor) of their retirements, optionally since an ISO-8601 timestamp — the statement a human settles in one transfer.
`offsets__net_position`	Buyer's carbon position: emitted (from agent-compute-ledger) minus retired. carbon_accountable == true when fully offset.

`surety__activate_bond`	Mark a POSTED bond ACTIVE (idempotent). funding_ref links the payment rail transaction that funded the stake.
`surety__file_claim`	File a claim against an ACTIVE bond. Claims pay out ONLY when an arbitration ruling upholds them (see slash_bond).
`surety__slash_bond`	Execute an arbitration ruling against a claim. Requires the ruling's case id + content hash from agent-arbitration — no ruling, no slash; a given ruling pays at most once. Payout caps at the bond's available balance (over-claims exhaust the bond).
`surety__release_bond`	Release the remaining stake to the principal after the coverage window elapses — refused while any claim is still open.
`surety__bond_status`	Current record for a bond (state, balances, claims, audit head).

`wavefunction__describe_agent`	Return capabilities and input contract.
`taxcredit-engine__calculate_tax_credit`	Calculate an auditable tax-credit scenario. credit is 45Q, 45V, 45Y, 48E, or 45X. facts must contain the explicit credit-specific eligibility facts; missing facts return indeterminate. This is not tax or filing advice.

`ghg-ledger__calculate_inventory`	Calculate an auditable GHG inventory from explicit activity records. Returns per-line gas/CO2e results, Scope 1/2/3 and category rollups, dual Scope 2 reporting, indeterminate lines, factor lineage, notary payload, and an offset-clearinghouse dry-run weave. This is calculation, not advice.
`ghg-ledger__classify_activity`	Suggest scope and Scope 3 category from the bundled deterministic map. No inference is used; unknown activity types return no suggestion.
`ghg-ledger__list_factor_packs`	List the bundled pack version/digest, supported regions and years, activity types, GWP set, and explicit MVP coverage.
`ghg-ledger__get_factor_pack`	Return factors, GWP values, conversions, sources, and pack SHA for one exact bundled region/year. No nearest-region or nearest-year substitution.

Status

LIVE. The gateway hosts 21 agents plus /subscriptions/mcp at https://mcp.viridisconservation.com (21/21 agents healthy; subscriptions v0.1.0 healthy), with Registry manifests under io.github.jdhart81/*. Since 2026-07-11 the gateway is durable: every state change (escrows, identities, certificates, meters, ledgers) is persisted before the caller sees the result and survives restarts — verified in production. Genesis receipts for the fleet's first self-transaction are in docs/GENESIS_RECEIPTS.md.

Pricing — built for network growth

The rails are free, forever. Identity, trust, escrow, metering, arbitration, compute-ledger, covenant, provenance, offsets, ERC-8004 bridge, surety, notary, and discovery cost nothing to call — the rails ARE the network, and we don't tax adoption of the thing whose value is adoption.

The paid services are penetration-priced for agent budgets: smartscale $0.50/call, protogen $1.00/call, taxcredit-engine $2.00/call, ghg-ledger $1.00/inventory, quantity-takeoff $0.50/takeoff, disclosure-compiler $2.00/draft, narrative-engine $0.50/call, and regulatory-radar $0.25/call — after 10 free calls per day. Pay once by Stripe Checkout (create_payment on /payments/mcp), then convert the payment into call credits with redeem_payment(session_id, agent) — credits = amount ÷ price, idempotent, never expire. A2A callers settle per-call via the x402/escrow idiom. Price raises only ever happen via pre-committed public triggers, and purchased credits are always honored.

The separate B2B catalog currently exposes five draft monthly-seat plans at $99–$249/month with 1,000 included calls and exact per-call overage. All five are coverage-ready, including the Energy, Climate, and Compliance bundles now unlocked by disclosure-compiler. Checkout remains fail-closed until Viridis approves final prices and quota and adds the corresponding recurring Stripe Price IDs. No plan is active merely because it appears in the catalog.

Escrow, offsets, and metering remain coordination state machines — custody stays on the payment rail. See docs/A2A_ECONOMY.md.
