detach_process · MCP Debug Server MCP: Risk & Policy

WHAT IT DOES

What detach_process does on MCP Debug Server

AI agents invoke detach_process 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 detach_process needs a policy

Detaching the debugger from a process is an external operation that affects the debugging session and the target process's execution state. It is not purely read, does not delete data, and has no financial implications. It triggers an operational change (resuming process execution without debugger control), which fits Execute.

Verdict

detach_process Rate-limited

detach_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.

PolicyLayer is an MCP gateway: every tool call is checked against your rule before it reaches MCP Debug Server, so you can run agents against it safely.

FAQ

Questions about detach_process

What does the detach_process tool do? +

Detach debugger from current process. It is categorised as a Execute tool in the MCP Debug Server 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_process? +

Register the MCP Debug Server MCP server in PolicyLayer and add a rule for detach_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 Debug Server. Nothing to install.

What risk level is detach_process? +

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

Can I rate-limit detach_process? +

Yes. Add a rate_limit block to the detach_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_process completely? +

Set action: deny in the PolicyLayer policy for detach_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_process? +

detach_process is provided by the MCP Debug Server MCP server (nickzer0/mcp-debugserver). PolicyLayer sits as a proxy in front of this server to enforce policies before tool calls reach the server.
