rmq_queue_create · RedisNexus MCP: Risk & Policy

WHAT IT DOES

What rmq_queue_create does on RedisNexus

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

WHY IT NEEDS A POLICY

Why rmq_queue_create needs a policy

This tool creates new RabbitMQ infrastructure resources, which is a reversible write operation. While it modifies system state by adding queues, it does not execute arbitrary code, delete data irreversibly, or move funds.

From the tool's definition Tool name 'rmq_queue_create' and description 'Create a new RabbitMQ queue' explicitly indicates data creation with configurable parameters (durability, TTL, max-length).

rmq_queue_create Rate-limited

rmq_queue_create 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.
