[RefImpl] Python Guardian sample with FastMCP client instrumentation #135

Target runtime or language

Python, as a sample Guardian plus FastMCP client instrumentation under samples/

What this proves

That a Python Guardian can govern an MCP client through FastMCP instrumentation, and that the sample carries its own conformance test in CI rather than a README claim. It is the smallest runnable path for a Python implementer who wants to see ACS work before reading the specification.

Do you intend to implement this yourself

No, I am proposing it for someone else

Filed by a maintainer so PR #78 has an issue to reference. @angelnicolasc wrote it and is assigned.
