概要

What is cipher-x402-mcp?

cipher-x402-mcp is an MCP server that provides eight Solana, crypto, and macroeconomic tools to any MCP‑aware client. Seven tools are gated behind the x402 payment protocol (USDC on Base, $0.005–$0.25 per call), and one educational tool is free. The server acts as a forward‑only relay, never holding caller funds, and is MIT‑licensed.

How to use cipher-x402-mcp?

Install via npx -y cipher-x402-mcp and add the configuration to Claude Desktop, Cursor, Cline, Continue, or any MCP‑over‑stdio client. For remote HTTP transport, deploy to Vercel (the /mcp route serves JSON‑RPC messages). The free tool and self‑hosted setup require no API keys.

FAQ from cipher-x402-mcp

What is the free tool?

The free tool is solana_wallet_security_audit_rules(), which returns a local ruleset for auditing Solana wallet security. It does not require a payment.

How does x402 payment work?

The agent calls a paid tool without payment, receives an HTTP 402 response with an accept‑list, signs an EIP‑3009 authorization for the required USDC amount, and re‑invokes the tool with the signed header. The server forwards the payment to the upstream facilitator for settlement on Base.

What MCP clients are supported?

Claude Desktop, Cursor, Cline, Continue, and any client that supports MCP over stdio. The server also provides a streamable HTTP transport at https://cipher-x402-mcp.vercel.app/mcp.

Can I self‑host the server?

Yes. Clone the repository, run npm install && npm run build, then use npm start for stdio or npm run start:http for HTTP. Requires Node.js 20+ and no API keys.
