AgentFi MCP Server

Crypto transaction tools for AI agents. 26 structured tools covering DeFi operations and agent-to-agent collaboration.

AgentFi gives AI agents their own crypto wallets, policy-bounded on-chain execution, and direct access to DeFi — without handling private keys or managing gas. Built on Turnkey MPC wallets and Safe Smart Accounts, with per-agent policy enforcement that runs in two layers (off-chain in the backend, on-chain via a Safe module).

Tools (26)

DeFi (15)

• Swaps — Uniswap V3, Curve StableSwap
• Yield — Aave V3, Compound V3, any ERC-4626 vault (Yearn, Morpho, Beefy, Gearbox, etc.)
• Transfers — ETH and ERC-20
• Balances — native + known ERC-20 tokens per chain

Agent-to-Agent (11)

• Job queue — publish paid tasks, accept, complete, cancel
• Atomic payments — rewards auto-settle on job completion with full policy + simulation + fee pipeline
• Escrow — funds reserved at job creation, released on terminal state
• Reputation — score 0–10 000 from real on-chain metrics with time-decay
• Discovery — search peer agents by service manifest
• P&L — earnings vs costs (protocol fees, A2A payments, gas) per agent
• Trust reports — reputation + tx history

Supported Networks

Ethereum Mainnet (1), Base (8453), Arbitrum One (42161), Polygon (137).

Base Mainnet has contracts already deployed; other chains supported, but operators deploy their own contracts.

Configuration

{
  "mcpServers": {
    "agentfi": {
      "command": "npx",
      "args": ["-y", "@agent_fi/mcp-server@0.2.0"],
      "env": {
        "AGENTFI_API_URL": "https://api.your-instance.com",
        "AGENTFI_API_KEY": "agfi_live_..."
      }
    }
  }
}

Setup

1. Run an AgentFi backend — open-source, self-hosted. Guide: production-deploy.md. Reference deployment uses Railway; Fly.io / Render / Docker documented as alternatives.
2. Register an agent — POST /v1/agents returns an API key (shown once).
3. Point this MCP server at it — set AGENTFI_API_URL and AGENTFI_API_KEY in the config above.

Security

• Turnkey MPC — private keys are split across shards and never reconstructed.
• Safe Smart Wallets — every transaction is validated on-chain against the agent's policy (max value, contract allowlist, cooldowns, kill switch).
• Pre-broadcast simulation — every tx is simulated via Tenderly before submission; reverts are caught without spending gas.
• Two-layer enforcement — even if the backend is compromised, the Safe refuses transactions that violate policy.
