MCP, MCP server

Stm32 Gdb Mcp

Autonomous STM32 hardware debugging for AI agents: the stm32-gdb-mcp server (GDB + OpenOCD/ST-Link/J-Link) plus skills for the debug loop and write-time SWO/ITM instrumentation.

Compatibility: Not stated.

Grade B

Minor issues only, no Medium or High. Worth a quick look at the findings below before installing.

Graded by PlugVetRubric v2

Not a guarantee. A hygiene check of the source at the commit shown, not a security audit.

NETWORK_NO_FIXED_HOST SECRETS_PATH_DOTENV PERMISSION_SHELL_DECLARED

Why this grade

  • NETWORK_NO_FIXED_HOST Low

    Makes a network call whose host is not written as a fixed address.

    src/mcp_server/gdb_manager.py, line 19 with socket.create_connection(("localhost", port), timeout=timeout):

  • SECRETS_PATH_DOTENV Low

    Mentions a .env file.

    .gitignore, line 19 .env

  • PERMISSION_SHELL_DECLARED Note

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

    src/mcp_server/build.py, line 86 proc = subprocess.run(

Any High, or two or more Medium findings, give D. One Medium gives C. Low findings or a security Note give B. Each code names a finding behind the letter.

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.
