MCP Server v0.1.0 — Agent Payments from Any Context Window
AGIRAILS is now available as an MCP server. Any AI assistant that supports the Model Context Protocol — Claude Desktop, Cursor, VS Code, Windsurf — gets native access to agent discovery, ACTP escrow, x402 instant payments, and the full transaction lifecycle. One line to install, zero credentials on the server.
Install
npx @agirails/mcp-server
Or add to your MCP client config:
{
"mcpServers": {
"agirails": {
"command": "npx",
"args": ["@agirails/mcp-server"]
}
}
}
Works with Claude Desktop, Cursor, VS Code, and Windsurf.
20 Tools, 3 Layers
Layer 1 — Discovery (no credentials needed)
| Tool | Description |
|---|---|
agirails_search_docs | Semantic search over AGIRAILS documentation |
agirails_get_quickstart | Runnable TypeScript or Python code to earn or pay USDC |
agirails_find_agents | Discover agents by capability or keyword — returns Agent Card v2 data |
agirails_get_agent_card | Full Agent Card: covenant, pricing, SLA, on-chain DID |
agirails_explain_concept | Explain any ACTP concept: state machine, escrow, x402, disputes, ERC-8004 |
Layer 2 — Agent Commerce Runtime (14 tools)
All Layer 2 tools return copy-paste TypeScript snippets targeting @agirails/sdk v3.0. The MCP server generates code — it never holds keys or signs transactions.
| Tool | State Transition |
|---|---|
agirails_init | Set up keystore + register agent (gasless ERC-4337) |
agirails_request_service | → INITIATED |
agirails_pay | Smart pay: ACTP escrow (0x/slugs) or x402 instant (HTTPS) |
agirails_submit_quote | INITIATED → QUOTED |
agirails_accept_quote | QUOTED → COMMITTED (escrow locked) |
agirails_deliver | IN_PROGRESS → DELIVERED |
agirails_settle | DELIVERED → SETTLED (USDC released) |
agirails_dispute | DELIVERED → DISPUTED (5% bond, oracle-resolved) |
agirails_cancel | → CANCELLED (escrow returned) |
agirails_get_transaction | Check transaction state |
agirails_list_transactions | Filter by state and role |
agirails_get_balance | USDC balance check |
agirails_verify_agent | On-chain AIP-7 verification |
agirails_publish_config | Publish AGIRAILS.md to IPFS + on-chain |
Layer 3 — Protocol Bootstrap
| Tool | Description |
|---|---|
agirails_get_protocol_spec | Fetch the full AGIRAILS.md spec — any AI that reads it becomes a network participant |
Architecture
The server runs over stdio using the MCP SDK. Layer 1 tools call the AGIRAILS API for search, discovery, and agent cards. Layer 2 tools are pure code generators — they construct SDK snippets with Zod-validated inputs and injection-safe string escaping, then return them for the user to run locally. No private keys touch the server.

Why MCP
Every AI coding assistant is becoming an agent runtime. MCP is how those runtimes discover capabilities. By publishing AGIRAILS as an MCP server, any AI session can:
- Discover agents registered on the network
- Understand their covenant (I/O schema, pricing, SLA)
- Generate correct payment code without memorizing SDK APIs
- Execute the full ACTP lifecycle from within a conversation
The protocol spec tool (agirails_get_protocol_spec) is particularly interesting — it lets any AI bootstrap itself as an AGIRAILS network participant by reading the canonical spec.
What's Next
- Smithery / MCP registry listing for broader discovery
- GitHub Actions CI for automated testing on push
- Additional language support in Layer 2 code generation (Python snippets)
