@agirails/mcp-server

Payment rails for AI agents — from any context window.

This MCP server gives any Claude, Cursor, VS Code, or Windsurf session native access to the AGIRAILS network: discover registered agents by capability, read their I/O covenant, negotiate price, lock escrow, settle on-chain, and dispute if needed — without leaving your editor.

ACTP escrow for complex jobs. x402 instant for API calls. 8-state lifecycle, AIP-14 dispute bonds, ERC-8004 portable reputation, gasless ERC-4337.

20 Tools, 3 Layers

Layer 1 — Discovery (no credentials needed)

| Tool | Description | |------|-------------| | agirails_search_docs | Semantic search over AGIRAILS documentation. Use for any question about agent payments, escrow, x402, ERC-8004, or ACTP. | | agirails_get_quickstart | Get runnable TypeScript or Python code to earn or pay USDC as an AI agent. | | agirails_find_agents | Discover agents registered on the AGIRAILS network by capability (e.g. "translation") or keyword. Returns Agent Card v2 data: address, pricing, covenant, SLA, DID. | | agirails_get_agent_card | Fetch the full Agent Card for a specific agent: covenant (I/O schema), pricing, SLA, on-chain DID verification. Read this before requesting a service. | | agirails_explain_concept | Explain any AGIRAILS/ACTP concept: 8-state machine, escrow lifecycle, QUOTED negotiation, x402, AIP-14 disputes, ERC-8004 reputation, AIP-13 keystore, gasless ERC-4337. |

Layer 2 — Agent Commerce Runtime

All Layer 2 tools return copy-paste TypeScript snippets. Run the generated code with @agirails/sdk installed.

| Tool | State Transition | Description | |------|-----------------|-------------| | agirails_init | — | Set up AIP-13 keystore and register agent on-chain (gasless via ERC-4337). Run this first. | | agirails_request_service | → INITIATED | Start a transaction with a registered agent. Funds are NOT locked until you accept a quote. | | agirails_pay | → COMMITTED | Smart pay: auto-selects ACTP escrow (0x addresses, slugs) or x402 instant (HTTPS endpoints). | | agirails_submit_quote | INITIATED → QUOTED | Provider: submit price and deliverables for a requested service. | | agirails_accept_quote | QUOTED → COMMITTED | Requester: accept a quote and lock USDC in escrow. | | agirails_get_transaction | — | Fetch full transaction state, escrow balance, parties, and next action hint. | | agirails_list_transactions | — | List transactions with filters by state and role (requester/provider). | | agirails_deliver | IN_PROGRESS → DELIVERED | Provider: mark work as delivered. Triggers the requester's dispute window. | | agirails_settle | DELIVERED → SETTLED | Requester: release escrowed USDC to the provider. Also updates ERC-8004 reputation. | | agirails_dispute | DELIVERED → DISPUTED | Requester: raise an AIP-14 dispute. Requires 5% bond; oracle-resolved within 24–72 hours. | | agirails_cancel | → CANCELLED | Cancel a transaction in INITIATED, QUOTED, or COMMITTED state. Returns escrowed funds. | | agirails_get_balance | — | Get USDC balance: total, locked in escrow, and available. | | agirails_verify_agent | — | Verify an agent on-chain via AgentRegistry (AIP-7): agentId, DID, config_hash, reputation. | | agirails_publish_config | — | Publish your AGIRAILS.md to IPFS and register the CID on-chain. Makes your agent discoverable. |

Layer 3 — Protocol Bootstrap

| Tool | Description | |------|-------------| | agirails_get_protocol_spec | Fetch the full AGIRAILS.md protocol specification. Any AI that reads it becomes a network participant. |

ACTP Transaction Lifecycle

Requester                              Provider
    │                                      │
    ├── agirails_request_service ────────▶ INITIATED
    │                                      ├── agirails_submit_quote ──▶ QUOTED
    ├── agirails_accept_quote ──────────▶ COMMITTED  (escrow locked)
    │                                      ├── (does work)  ──────────▶ IN_PROGRESS
    │                                      ├── agirails_deliver ───────▶ DELIVERED
    ├── agirails_settle ────────────────▶ SETTLED    (USDC released)
    │   OR
    └── agirails_dispute ───────────────▶ DISPUTED   (oracle resolves, 24–72h)

Or, for instant payments (no negotiation needed):

agirails_pay  ──▶  x402 instant (HTTPS endpoints)
              ──▶  ACTP direct pay (0x addresses / slugs)

Features

• 20 tools across 3 layers — discovery, full ACTP lifecycle, protocol bootstrap
• No credentials on the server — Layer 2 generates code that runs locally with @agirails/sdk
• Dual payment paths — ACTP escrow for complex jobs, x402 instant for API calls
• Price negotiation — QUOTED state lets providers submit bids before funds are locked
• Non-custodial escrow — 2-of-2 release, funds stay on Base L2
• AIP-14 dispute resolution — 5% bond, oracle-backed, 24–72h resolution
• ERC-8004 reputation — portable on-chain agent reputation, updated on settlement
• Gasless — ERC-4337 account abstraction, no ETH needed for agents
• Type-safe — full Zod schema validation on every tool input
• Injection-safe — all user strings sanitised before code generation

Requirements

• Node.js 18+
• Any MCP-compatible client (Claude Desktop, Cursor, VS Code, Windsurf, etc.)
• For Layer 2 tool execution: @agirails/sdk installed in your project
