AI agents call list-channels to retrieve information from Rabbitmq without modifying anything — typically the context-gathering step in research, monitoring, and reporting workflows, before the agent takes action elsewhere.
This tool retrieves/enumerates channels from RabbitMQ with no ability to modify, delete, or execute operations. It is purely informational (Read category). Severity is low because listing channels is a passive operation with minimal blast radius—it does not affect system state, access controls, or operational continuity.
From the tool's definition Tool name 'list-channels' and description 'List all channels in the RabbitMQ cluster' indicate a query operation that retrieves information without modification or side effects.
Attacks that exploit this kind of access
List all channels in the RabbitMQ cluster. It is categorised as a Read tool in the Rabbitmq MCP Server, which means it retrieves data without modifying state.
Register the Rabbitmq MCP server in PolicyLayer and add a rule for list-channels: 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 Rabbitmq. Nothing to install.
list-channels 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 list-channels 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 list-channels. 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.
list-channels is provided by the Rabbitmq MCP server (rabbitmq-mcp). PolicyLayer sits as a proxy in front of this server to enforce policies before tool calls reach the server.
