gdb_enable_breakpoint · GDB MCP Server MCP: Risk & Policy

WHAT IT DOES

What gdb_enable_breakpoint does on GDB MCP Server

AI agents invoke gdb_enable_breakpoint 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_enable_breakpoint needs a policy

Enabling a breakpoint modifies the debugging session state by activating a previously disabled breakpoint, causing execution to pause when that breakpoint is hit. This is an operational change to the debug session rather than a simple read, and it affects program execution flow. It is reversible (can be disabled again), so it does not qualify as Destructive.
