About x402-trust-mcp
x402-trust-mcp is an MCP server published by the GitHub account JonasFuchss. Discover x402 endpoints and check their trust score before your agent pays them.
It runs on your own machine: your AI client starts it from the npm package x402-trust-mcp at version 1.16.0.
It asks for one secret: X402_PRIVATE_KEY. Give it a key with the least access that still works.
Version 1.16.0 was published on 15 October 2026, and the source code is public, so you can read it before installing.
Written from the registry entry. 9 automated checks on the registry entry and the package code: 7 pass, 0 warn, 0 fail, 2 info. How we check.
