@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:
