    Runs shell commands, and the manifest or description says so.

    src/shapr3d_mcp/server.py, line 256 proc = subprocess.run(

Grades are a hygiene check of the source at the commit shown, on the date checked, not a security audit or a guarantee. The free directory grades are automated. Before release, a PlugVet engineer reviews every paid report and any grade we hold back, including all F grades, against the source code and the evidence we quote.
