attach · WineDbg MCP Server MCP: Risk & Policy

WHAT IT DOES

What attach does on WineDbg MCP Server

AI agents invoke attach 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 attach needs a policy

Attaching a debugger to a process is an Execute-category action: it does not merely read data but actively intervenes in a running process, suspending it and allowing inspection and manipulation. Misuse could disrupt or crash the target process, giving it high severity.

From the tool's definition "Attach to a process" — attaches the Wine debugger to a running process, triggering external debugger operations and gaining control over process execution

Verdict

attach Rate-limited

attach 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.

What risk level is attach? +

attach is a Execute tool with high risk. Execute tools should be rate-limited and have argument validation enabled.

Can I rate-limit attach? +

Yes. Add a rate_limit block to the attach rule in your PolicyLayer policy. For example, setting max: 10 and window: 60 limits the tool to 10 calls per minute. Rate limits are tracked per agent session and reset automatically.

How do I block attach completely? +

Set action: deny in the PolicyLayer policy for attach. The AI agent will receive a policy violation error and cannot call the tool. You can also include a reason field to explain why the tool is blocked.

What MCP server provides attach? +
