AI agents call list-stream-publishers 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 information about stream publishers in RabbitMQ without creating, modifying, deleting, or executing any operations. It is a read-only query that poses minimal security risk as it only exposes existing cluster metadata.
From the tool's definition Tool name 'list-stream-publishers' and description 'List all stream publishers in the RabbitMQ cluster' indicate a query/retrieval operation with no data modification or side effects.
Attacks that exploit this kind of access
List all stream publishers 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-stream-publishers: 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-stream-publishers 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-stream-publishers 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-stream-publishers. 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-stream-publishers 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.
