create_minidump · MCP Debug Server MCP: Risk & Policy

WHAT IT DOES

What create_minidump does on MCP Debug Server

AI agents invoke create_minidump 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 create_minidump needs a policy

Creating a minidump involves executing a privileged OS-level operation that captures process memory state and writes it to disk. While not purely destructive (the process continues), it can expose sensitive memory contents (credentials, keys, PII) and constitutes an active execution of a system-level operation.

From the tool's definition 'Generate minidump on demand' — actively triggers a dump of process memory to disk

Verdict

create_minidump Rate-limited

create_minidump 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 create_minidump? +

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

Can I rate-limit create_minidump? +

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

Set action: deny in the PolicyLayer policy for create_minidump. 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.
