db_mongodb_query · Infra Ops MCP: Risk & Policy

WHAT IT DOES

What db_mongodb_query does on Infra Ops

AI agents invoke db_mongodb_query to trigger actions in Infra Ops. 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 db_mongodb_query needs a policy

Although 'find' is typically a read operation, the tool is described as executing a query, which runs code against an external system. MongoDB queries can include operators and JavaScript expressions that may have side effects or expose sensitive data at scale. On an infra-ops server with broad access, misuse could expose sensitive production data.

From the tool's definition 'Execute a MongoDB find query on a collection' — the tool runs a query operation against a live MongoDB database

Verdict

db_mongodb_query Rate-limited

db_mongodb_query 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.
