finish · WineDbg MCP Server MCP: Risk & Policy

WHAT IT DOES

What finish does on WineDbg MCP Server

AI agents invoke finish to trigger actions in WineDbg 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 finish needs a policy

This tool controls execution flow of a debugged process by running it until the current function completes. It is an Execute-category action as it directly drives program execution in the Wine debugger context.

From the tool's definition 'Finish execution of the current function' — triggers a debugger step-out operation that resumes execution of the debugged process until the current function returns

Verdict

finish Rate-limited

finish 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.
