WHAT IT DOES

What toggle_hardware_breakpoint does on MCP Debug Server

AI agents invoke toggle_hardware_breakpoint to trigger actions in MCP Debug 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 toggle_hardware_breakpoint needs a policy

Toggling a hardware breakpoint directly controls debugger execution flow at the CPU/hardware level. Enabling a hardware breakpoint causes the CPU to interrupt execution when a specific memory address is accessed or executed, which can affect process behavior, cause crashes, or be used to manipulate program flow. This is an active execution-control operation on a live process, placing it in the Execute category.
