detach_from_process · Mcp Debugger MCP: Risk & Policy

WHAT IT DOES

What detach_from_process does on Mcp Debugger

AI agents invoke detach_from_process to trigger actions in Mcp Debugger. 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 detach_from_process needs a policy

This tool performs an external operation on a running process (detaching a debugger), which is an active action that affects the state of the debug session and the target process. It is not purely a read operation, and since it explicitly does not terminate the process (ruling out Destructive), Execute is the most appropriate category.

Verdict

detach_from_process Rate-limited

detach_from_process 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.

FAQ

Questions about detach_from_process

What does the detach_from_process tool do? +

Detach from the debugged process without terminating it. It is categorised as a Execute tool in the Mcp Debugger MCP Server, which means it can trigger actions or run processes. Use rate limits and argument validation.

How do I enforce a policy on detach_from_process? +

Register the Mcp Debugger MCP server in PolicyLayer and add a rule for detach_from_process: allow, deny, rate-limit, or require approval. Point your MCP client at the PolicyLayer proxy URL and the rule is enforced on every call, before it reaches Mcp Debugger. Nothing to install.

What risk level is detach_from_process? +

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

Can I rate-limit detach_from_process? +

Yes. Add a rate_limit block to the detach_from_process 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 detach_from_process completely? +

Set action: deny in the PolicyLayer policy for detach_from_process. 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 detach_from_process? +

detach_from_process is provided by the Mcp Debugger MCP server (@debugmcp/mcp-debugger). PolicyLayer sits as a proxy in front of this server to enforce policies before tool calls reach the server.
