Coding agents run multi-leg cross-chain DeFi. Legs re-derived from your sentence before signing.

xyz.getava/ava (MCP) Server

xyz.getava/ava is an MCP server used by coding agents for multi-leg cross-chain DeFi. It re-derives each “leg” from the user’s sentence before signing, then exposes functionality via 15 tools for those agent workflows.

🛠️ Key Features

Multi-leg cross-chain DeFi support
Leg derivation is based on the input sentence before signing
15 available tools

🚀 Use Cases

Preparing multi-step cross-chain DeFi actions for coding agents
Converting a natural-language sentence into signing-ready legs

⚡ Developer Benefits

Tool-based integration (15 tools) for agent-driven DeFi flows
Deterministic step derivation tied to the sentence content (before signing)

⚠️ Limitations

Description provided does not specify supported chains, protocols, authentication methods, or error-handling behaviors.

ava_copilot_turn

Natural-language copilot turn: message → intent → plan → testnet quote. Example: Swap 10 USDC to SUI on sui with 50 bps slip. Returns actions with approve_execute + executionId. Optional agentId/agentCredential for KYA gate (fail closed on reject). Does NOT fill until ava_approve_execute.

Parameters6

message	string	required
portal	string	optional
userId	string	optional
mode	string	optional
agentId	string	optional	Optional agent id; uses a default testnet-scoped KYA credential when full agentCredential is omitted.
agentCredential	object	optional	Optional ava.kya.agent-credential.v1 object for KYA evaluation.

ava_approve_execute

Human-in-the-loop approve: the one call that actually settles a plan from ava_copilot_turn. It is gated by the bound mandate's status and constraints and by server-side policy limits, and it CAN REFUSE (e.g. mandate paused/cancelled, a policy violation, a stale preview hash); a refusal means no funds moved and no success receipt was written, only a refusal record. Testnet mode settles against simulated balances and returns a receipt + before/after balances, never a real chain. Mainnet mode signs with the caller's own Turnkey wallet and submits for real where a venue is live, and fails closed everywhere else, so it never claims a fill it cannot show. Call ava_list_venues for which routes are live rather than assuming; that tool reads the same registry this one enforces, so it cannot drift from what will actually execute. NEVER call without explicit user confirmation of the previewed quote.

Parameters5

executionId	string	required	executionId from actions[].type === approve_execute on the prior copilot turn
userId	string	required	Same userId used on ava_copilot_turn / portfolio
portal	string	required	Portal slug matching the pending plan (e.g. sui)
mode	string	optional	Default testnet. Live is fail-closed without a submit path.
previewHash	string	optional	previewHash from ava_preview_tx. Binds the signature to the artifact the human reviewed; a stale hash fails before signing.

ava_lend_execute

Execute a REAL lend against one of your mandates. Routes Ava has already settled a mainnet transaction on: Morpho Blue on Base, and Aave v3 on Monad, BNB Chain and Avalanche. Aave v3 on Arbitrum One is wired through the identical pipeline and address-verified, but nothing has ever settled there, so do not describe it as proven. Aave v3 on Optimism and Base, and Compound v3 on Base and Arbitrum, are wired and address-verified but operator-disabled until each settles a real transaction, so calls on those routes refuse at the capability gate. This is the only MCP tool that moves live capital. Two-phase by design: call it once WITHOUT previewHash to receive the exact artifact a human must approve plus its hash, show that to the human, then call again WITH that previewHash. Your call is never treated as the human's confirmation, because you are not the person whose money moves. Only a settlement verified against the venue's own on-chain event returns a txHash; anything else has no txHash field at all, so a draft can never be narrated as a fill.

Parameters8

mandateId	string	required	The mandate authorising this capital. Required: Ava will not choose which of the user's authorisations to spend. From ava_create_mandate or ava_list_mandates.
op	string	optional	Supply into the venue or withdraw from it. Defaults to supply.
amount	string	optional	Human decimal amount of the mandate's asset. Defaults to the mandate's full capital when omitted.
venue	string	optional	Venue selector for chains carrying more than one wired lend venue. Absent keeps the chain's default: Base -> Morpho, every Aave v3 chain -> Aave v3. On Base, name aave_v3 or compound to reach those routes; naming a venue the chain does not carry refuses rather than rerouting.
previewHash	string	optional	The hash returned by the first call, after a human approved that exact artifact. Omit on the first call.
idempotencyKey	string	optional	Your own key for this economic action. Supply the SAME key when retrying: a fresh key per attempt makes every retry look new, which is exactly what defeats single-flight protection. Required for the compound route, whose reservation is durable.
userId	string	required
portal	string	optional

ava_portfolio

Simulated testnet portfolio for a userId (same data as GET /v1/portfolio): seeded balances, fills, optional portal. Requires userId. Does not invent live chain balances.

Parameters2

portal	string	optional	Portal slug (default base)
userId	string	required	Required user id (from POST /v1/users/session or x-ava-user-id)

Raw schema

{
  "type": "object",
  "properties": {
    "portal": {
      "type": "string",
      "description": "Portal slug (default base)"
    },
    "userId": {
      "type": "string",
      "description": "Required user id (from POST /v1/users/session or x-ava-user-id)"
    }
  },
  "required": [
    "userId"
  ]
}

ava_session

Create or resume a human/org identity (userId), the first call in the loop. One human can own many agent instances (Claude + Cursor + OpenClaw + Ava-hosted). Moves no money and provisions no wallet by itself; call once and reuse the returned userId on every other tool.

Parameters2

userId	string	optional	Reuse existing userId if known
displayName	string	optional

Raw schema

{
  "type": "object",
  "properties": {
    "userId": {
      "type": "string",
      "description": "Reuse existing userId if known"
    },
    "displayName": {
      "type": "string"
    }
  },
  "required": []
}

ava_create_agent

Register an agent instance under userId, before it has a wallet or a mandate. Mode A (multi-agent): agentId=byo-external + label (e.g. claude-workspace, cursor-arb) for a coding agent that already exists elsewhere. Mode B (hosted): agentId=defi-lend|defi-swap|defi-perp|portfolio hires an Ava-run agent. One userId may own many agent instances; this call alone never touches funds.

Parameters4

userId	string	required
portal	string	required
agentId	string	required	Catalog id e.g. byo-external, defi-lend, defi-swap, defi-perp, portfolio
label	string	optional	Optional label to distinguish agents under one human (e.g. claude-workspace, cursor-home, openclaw-night).

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

    },
    "agentId": {
      "type": "string",

    }
  },
  "required": [
    "userId",
    "portal",
    "agentId"
  ]
}

ava_provision_wallet

Provision a Turnkey-custodied wallet address for this userId, scoped to one chain family (evm | solana | sui). Requires ava_session first. Returns the address for funding and later signing; it does not fund the wallet and does not move any money. If Turnkey is not configured server-side, the wallet comes back with status pending_provision rather than a fabricated active address, and cannot sign or hold funds until it is active.

Parameters2

userId	string	required
family	string	required

Raw schema

{
  "type": "object",
  "properties": {
    "userId": {
      "type": "string"
    },
    "family": {
      "type": "string",
      "enum": [
        "evm",
        "solana",
        "sui"
      ]
    }
  },
  "required": [
    "userId",
    "family"
  ]
}

ava_preview_tx

Pre-sign preview: build the exact venue artifact (CoW EIP-712 order or unsigned Solana transaction) for a pending plan against the provisioned Turnkey wallet, simulate it where supported, and return it UNSIGNED. Nothing is signed or submitted. Show the artifact to the human, then pass the returned previewHash to ava_approve_execute so the signature covers exactly what was reviewed.

Parameters3

executionId	string	required	executionId from the prior ava_copilot_turn approve_execute action
userId	string	required
portal	string	required	Portal slug matching the pending plan

Raw schema

{
  "type": "object",
  "properties": {
    "executionId": {
      "type": "string",
      "description": "executionId from the prior ava_copilot_turn approve_execute action"
    },
    "userId": {
      "type": "string"
    },
    "portal": {
      "type": "string",
      "description": "Portal slug matching the pending plan"
    }
  },
  "required": [
    "executionId",
    "userId",
    "portal"
  ]
}

ava_plan_workflow

Turn ONE natural-language DeFi request into the dependent actions it actually contains, across one chain or several. Example: "Supply 300 USDC to Morpho on Base, bridge no more than 200 to Avalanche, then supply what arrives to Aave" returns three legs with the third depending on the second and taking its amount from what the bridge actually delivered, not a plan-time guess. Same-chain works identically: "swap 100 USDC to WETH on Base then supply the WETH to Aave" records the swap OUTPUT token so the second leg is denominated in WETH. Plans nothing it cannot execute: a clause naming an unsupported operation, an unnamed venue, a zero or negative amount, or one amount split across venues comes back in `unsupported` with a reason rather than being guessed at. Signs nothing and moves nothing. Every leg reports `executable` so you can see what Ava could actually run today.

Parameters2

message	string	required	The user's request, verbatim. Do not pre-parse it.
userId	string	required

Raw schema

{
  "type": "object",
  "properties": {
    "message": {
      "type": "string",
      "description": "The user's request, verbatim. Do not pre-parse it."
    },
    "userId": {
      "type": "string"
    }
  },
  "required": [
    "message",
    "userId"
  ]
}

ava_plan_standing

Turn a request for REPEATED autonomous action into an envelope of bounds the user signs once. Use this instead of ava_plan_workflow when the request describes a cadence: "every hour, rotate my USDC into the best yield on Base using Aave and Morpho, never move more than 200 per rotation, never exceed 1000 total, stop after 30 days". Asking a human to approve each rotation would defeat the point, so the user authorizes LIMITS rather than a plan: allowed operations, venues, chains, per-move and cumulative caps, a minimum gain that stops the agent churning capital for fees, an expiry, and revocation. Every bound must come from the user: anything missing is returned in `missing` and the envelope is NOT signable until supplied. minGainBps is required from you because users say "the best yield" rather than a basis-point floor, and Ava must not choose how much of their money goes to gas. Returns the envelope unsigned; nothing is authorized until the user signs it.

Parameters3

message	string	required	The user's request, verbatim.
minGainBps	number	optional	Minimum improvement, in basis points, a rotation must beat to be worth its fees. Ask the user; do not invent it.
userId	string	required

Raw schema

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

    "minGainBps": {
      "type": "number",
      "description": "Minimum improvement, in basis points, a rotation must beat to be worth its fees. Ask the user; do not invent it."
    },
    "userId": {
      "type": "string"
    }
  },
  "required": [
    "message",
    "userId"
  ]
}

ava_create_mandate

Create a capital mandate: the objective, capital and constraints an agent is allowed to act under, optionally scoped to an agentInstanceId. Example: "Earn on 500 USDC on Base, max 5% drawdown". Or pass structured capital {asset,amount,chain}. Creating a mandate moves no money by itself and is not yet signed by an external wallet: it is Ava's own record of what was asked for, not a user-authorised instruction a stranger can rely on. Every later ava_approve_execute run under this mandate is gated on its status (active/paused/cancelled) and constraints, and can refuse.

Parameters9

portal	string	required
message	string	optional
capital	object	optional
objective	string	optional
constraints	object	optional
conditions	array	optional
userId	string	optional
name	string	optional
agentInstanceId	string	optional	Optional: bind mandate to one agent under the user (BYO or hosted)

ava_list_mandates

List capital mandates for a userId (optional filter by agentInstanceId).

portal	string	optional
userId	string	required
status	string	optional
agentInstanceId	string	optional

  "type": "object",

    },
    "agentInstanceId": {
      "type": "string"
    }
  },
  "required": [
    "userId"
  ]
}

ava_eval_mandate

Read-only: check a mandate's exit conditions against a market snapshot and record the result. Omit snapshot to pull a live CoinGecko price for the condition asset. Never executes and never moves money; ava_approve_execute is the only tool that does.

Parameters2

mandateId	string	required
snapshot	object	optional

Raw schema

{
  "type": "object",
  "properties": {
    "mandateId": {
      "type": "string"
    },
    "snapshot": {
      "type": "object"
    }
  },
  "required": [
    "mandateId"
  ]
}

ava_agent_record

Read an agent's track record before delegating capital to it. Returns mandates held, executions attempted, refusals by typed code, and receipts with their proof standing. Distinguishes CLAIMED from PROVEN: receiptsProven counts only chain-confirmed receipts; unconfirmed receipts prove nothing. AP2-aligned (each receipt's ap2.reference is the hash of the closed mandate) so an AP2-aware verifier can check it. Owner-readable always; a stranger reads only if the owner opted the record public. Zero is zero, never a placeholder.

Parameters2

agentInstanceId	string	required	The agent to look up.
userId	string	optional	Caller identity (ava_session first). Owner sees the full record; others only a public one.

Raw schema

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

    "userId": {
      "type": "string",
      "description": "Caller identity (ava_session first). Owner sees the full record; others only a public one."
    }
  },
  "required": [
    "agentInstanceId"
  ]
}

ava_get_receipt

Retrieve the receipt for a prior ava_approve_execute by executionId, the loop's final step. Returns the stored receipt plus its honest proof.standing: none (nothing submitted), unconfirmed (an identifier exists but nothing independent confirmed it), chain-confirmed (the declared chain returned the transaction and it matches what the receipt claims), or chain-contradicted (the chain disagrees with the receipt). A verified receiptHash does not by itself mean chain-confirmed; read proof.standing, not just verified. Owner-scoped: only the userId the receipt was produced for can read it by executionId; also returns a receiptHash-addressed verify URL a stranger can check with no credential.

Parameters2

executionId	string	required	executionId returned by ava_copilot_turn / ava_approve_execute.
userId	string	optional	Same userId that produced the execution. Required for headerless callers.

  "type": "object",
