gdb_disconnect · GDB MCP Server MCP: Risk & Policy

WHAT IT DOES

What gdb_disconnect does on GDB MCP Server

AI agents invoke gdb_disconnect to trigger actions in GDB MCP Server. What it does depends on the arguments the agent supplies, and its effects often reach beyond the immediate call — builds kicked off, notifications sent, workflows started.

WHY IT NEEDS A POLICY

Why gdb_disconnect needs a policy

This tool terminates the GDB process and disconnects from the target board by sending a detach command. It executes an external operation (killing a process, detaching from a remote target) that has real side effects on the debugging session. While not destructive to data, it terminates an active process and remote connection, placing it in the Execute category.

Verdict

gdb_disconnect Rate-limited

gdb_disconnect stays usable, but rate-capped — a runaway agent can't fire it dozens of times a minute. Everything else on the server is denied unless you say otherwise.
