gdb_finish · GDB MCP Server MCP: Risk & Policy

WHAT IT DOES

What gdb_finish does on GDB MCP Server

AI agents invoke gdb_finish 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_finish needs a policy

This tool resumes execution of a debugged program until the current function returns, then pauses. It triggers execution of code in the target process, making it an Execute-category tool. Misuse could cause the program to advance past important breakpoints or execute unintended code paths, but it pauses at the function return so impact is bounded.

From the tool's definition 继续执行直到当前函数返回。在返回点暂停。 (Continue execution until the current function returns. Pause at the return point.)
