Test MCP servers and the agents that call them in pytest
SineFrame M3 is an innovative open-source testing tool designed for developers working with MCP servers and agents. Unlike traditional unit tests that only verify code passes, M3 ensures that the agents calling the MCP servers actually make the expected calls during real interactions. It leverages powerful AI models like Claude Code, Codex, OpenCode, or Pi to run real server tests and then asserts on the actual calls made, all within a straightforward pytest environment. The tool provides a transparent view of every trace and tool call through its UI, allowing developers to diagnose and verify interactions with precision. Additionally, M3 offers an integrated CI testing pipeline that can gate pull requests and store test runs on app.m3.sineframe.com, streamlining the development workflow. Its open-source nature under the Apache-2.0 license makes it accessible and customizable for teams focused on AI, developer tools, and open-source projects.
