attach_to_process · Mcp Debugger MCP: Risk & Policy

WHAT IT DOES

What attach_to_process does on Mcp Debugger

AI agents invoke attach_to_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 attach_to_process needs a policy

Attaching to a running process is an active operation that connects the debugger to an external process, enabling control over its execution (pause, step, evaluate, modify memory). This is not a passive read — it can affect the target process's behavior, performance, and security posture. Misuse could allow an AI agent to attach to sensitive system processes, exposing private data or disrupting operations.

Verdict

attach_to_process Rate-limited

attach_to_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 attach_to_process

What does the attach_to_process tool do? +

Attach to a running process for debugging. 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 attach_to_process? +

Register the Mcp Debugger MCP server in PolicyLayer and add a rule for attach_to_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 attach_to_process? +

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

Can I rate-limit attach_to_process? +

Yes. Add a rate_limit block to the attach_to_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 attach_to_process completely? +

Set action: deny in the PolicyLayer policy for attach_to_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 attach_to_process? +

attach_to_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.
