put-queue · Rabbitmq MCP: Risk & Policy

WHAT IT DOES

What put-queue does on Rabbitmq

AI agents use put-queue to create or update resources in Rabbitmq — usually the action step of a workflow, after the agent has gathered context. Every call changes real data in your Rabbitmq environment.

WHY IT NEEDS A POLICY

Why put-queue needs a policy

This tool creates or modifies queue resources in RabbitMQ. These operations are reversible through deletion or reconfiguration, making it a Write action rather than Destructive. Severity is medium because misconfiguration could disrupt message flow or create unexpected queues, but the effects are not permanent or irreversible like Destructive actions.

From the tool's definition Tool name 'put-queue' and description 'Create or update a queue' indicate reversible creation or modification of queue configurations.

Verdict

put-queue Rate-limited

put-queue stays usable, but capped — an agent stuck in a loop can't make hundreds of changes a minute. Everything else on the server is denied unless you say otherwise.
