x402 pay-per-call

Check an MCP server or package for registry risk

Assess an MCP server URL for supply-chain and registry risk before your agent connects to it or grants it tool-calling access: flags unverified publishers, known-malicious servers, and other trust signals. Call before an autonomous agent adds a new MCP server to its toolset.

Billing. $0.35 in USDC per call over x402, on Base or Solana. No API key, no signup and no subscription. Send the request with no payment header, take the 402 challenge that comes back, pay it, and repeat the request. Only successful calls are charged.
