cipher-x402-mcp

An MCP server exposing 8 Solana, crypto, and macro tools to any MCP client (Claude Desktop, Cursor, Cline, Continue). Seven tools are gated behind the x402 payment protocol — agents auto-pay in USDC on Base, 0.005 to 0.25 USDC per call. The server is a forward-only relay: when an agent calls a paid tool without an X-PAYMENT header, we surface the upstream HTTP 402 plus the accept-list verbatim so the agent's own wallet signs the payment. We never custody caller funds. Tools include Solana wallet scan, password breach check, Jito tip calculator, GitHub repo health, FRED macro series, Drift exposure, and a free Solana wallet security audit ruleset.
