gdb_continue · GDB MCP Server MCP: Risk & Policy

WHAT IT DOES

What gdb_continue does on GDB MCP Server

AI agents invoke gdb_continue 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_continue needs a policy

This tool resumes execution of a debugged program, triggering arbitrary code execution on the target system (embedded hardware, QEMU, or remote gdbserver). Misuse could cause the target system to enter unintended states, execute destructive code paths, or crash hardware. It is an Execute-category action with high severity due to the embedded/hardware context.

From the tool's definition 继续执行程序。程序将运行直到遇到断点或异常 (Continue executing the program from the current position. The program will run until it hits a breakpoint or exception)

Verdict

gdb_continue Rate-limited

gdb_continue 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.
