pwndbg_attach · Pwndbg Lldb MCP: Risk & Policy

WHAT IT DOES

What pwndbg_attach does on Pwndbg Lldb

AI agents invoke pwndbg_attach to trigger actions in Pwndbg Lldb. 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 pwndbg_attach needs a policy

Attaching to a running process is an active external operation that connects the debugger to a live process, allowing inspection and control of that process. This is not a simple read — it changes the state of the target process (pausing it, injecting the debugger). It triggers a significant external operation (debugger attachment) whose effects depend on the PID argument.
