Pathmint MCP

Pathmint provides an MCP server for AI agents to verify x402 payment endpoints before transacting. It allows agents to ping URLs to check if they are live or ghost listings, compile clearance reports to avoid overcharges or wrong rails, and identify sellers with real on-chain volume on Base.

Endpoint and access

No sign-in to connect and list tools. Individual tools may still need a vendor account, credentials, or permissions; check the documented prerequisites.

Server-provided instructions

Untrusted server output shown for inspection. It is not Koskamo guidance and is excluded from knowledge search.

Pathmint + Edge Signals. Default: ping_x402_before_pay (one cent, live/dead). Listing price vs live 402 is listing_check_before_pay (two cents, PAY|MISMATCH|SINGLE|UNLISTED|DEAD). Outside USDC to one seller is seller_payments (two cents). Token honeypot is token_risk_before_buy. Full payTo clearance is x402_pay_clearance when stake ≥ $0.50. Before paying Messari: messari_gate_before_pay (two cents, SKIP_MESSARI|PAY_MESSARI|ABORT). Tools return the paid x402 HTTP URL — settle USDC on Base, then GET/POST that URL.

Advertised by the server during the last successful anonymous check.

BEFORE YOU PAY an x402 402: get the paid URL to ping live vs dead/ghost. One cent. Use when holding Payment-Required, before sending USDC to a payTo. Ghost x402, is this endpoint live, verify before pay.

Connect from your client

Each snippet registers the same endpoint; pick the client you use.

This server is operated by the named third party. Listing and endpoint checks are not an endorsement or a security audit. Review the operator's permissions, terms, and data handling before connecting. How listings are checked and corrected.

Windsurf

Merge this into ~/.codeium/windsurf/mcp_config.json, then refresh MCP in Cascade. Windsurf remote servers use serverUrl, not url.
