SineFrame M3
SineFrame
Pytest-based CI gate for MCP servers that tests them against real agents like Claude Code and Codex.
Key features
- Real Agent Harnesses: Runs Claude Code, Codex, OpenCode or Pi binaries so tool choice reflects real discovery and permission flows.
- Tool Call Assertions: Records every MCP tool call and lets tests assert expected calls and arguments.
- Direct Server Tests: Checks schemas, results and errors without a model in ordinary pytest files.
- Cross-Harness Comparison: Runs the same tests across harnesses and versions to catch regressions after agent updates.
- CI Gate: `m3 ci test` fails on broken assertions or when no tests executed at all.
- Bring Your Own Agent: Any agent speaking the Agent Client Protocol can be added via a manifest.
- Local Reports: Stores run history in SQLite and feedback reports, with an optional `m3 test --ui` viewer.
Best for
- MCP Regression Testing: Verify agents still call the right tool after changing tool descriptions.
- Agent Compatibility: Check whether a server that works in Claude Code also works in Codex or OpenCode.
- Release Gating: Block pull requests that break MCP behavior in CI.
- Upgrade Monitoring: Compare behavior across versions of Codex or other harnesses.
- Debugging Misrouted Calls: Inspect recorded tool calls to see why an agent asked for the wrong argument.
- Test Authoring: Hand setup to a coding agent via the copyable skill prompt.
