About Echoproof

Echoproof is an MCP server published by the GitHub account est57. Replay real HTTP traffic against base and changed builds; flag behavior changes the intent omits.

It runs on your own machine: your AI client starts it from the cargo package echoproof at version 0.4.0.

It asks for one secret: ANTHROPIC_API_KEY. Give it a key with the least access that still works.

Version 0.4.0 was published on 15 October 2026, and the source code is public, so you can read it before installing.

Written from the registry entry. 7 automated checks on registry metadata: 3 pass, 1 warn, 0 fail, 3 info. How we check.
