List all queues with message counts, consumer counts, and rates.
AI agents call rmq_queue_list to retrieve information from RedisNexus without modifying anything — typically the context-gathering step in research, monitoring, and reporting workflows, before the agent takes action elsewhere.
This tool performs a read-only operation that retrieves information about message queues. It returns observational data (counts, rates) with no side effects, mutations, or destructive actions. The blast radius of misuse is minimal—an AI could retrieve queue statistics but cannot alter, delete, or execute operations on the queues themselves.
From the tool's definition Tool name 'rmq_queue_list' and description 'List all queues with message counts, consumer counts, and rates' indicate a retrieval operation that queries queue metadata without modifying or deleting data.
Attacks that exploit this kind of access
List all queues with message counts, consumer counts, and rates. It is categorised as a Read tool in the RedisNexus MCP Server, which means it retrieves data without modifying state.
Register the RedisNexus MCP server in PolicyLayer and add a rule for rmq_queue_list: 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 RedisNexus. Nothing to install.
rmq_queue_list is a Read tool with low risk. Read-only tools are generally safe to allow by default.
Yes. Add a rate_limit block to the rmq_queue_list 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.
Set action: deny in the PolicyLayer policy for rmq_queue_list. 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.
rmq_queue_list is provided by the RedisNexus MCP server (rajkumar-madhu/mcp). PolicyLayer sits as a proxy in front of this server to enforce policies before tool calls reach the server.
rmq_queue_list is one line of RedisNexus's registry record.
The record carries the whole server: verified identity, auth posture, risk grade, every tool classified, recommended policy — re-checked continuously.
