AI agents call get-health-virtual-hosts 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 performs a health check query on virtual hosts, retrieving diagnostic status data. It has no side effects, does not modify data, and does not execute arbitrary code or trigger external operations. It is purely informational and falls clearly into the Read category with low severity due to minimal blast radius if misused.
From the tool's definition Tool name 'get-health-virtual-hosts' and description 'Get health check status for all virtual hosts' indicate a read-only query operation that retrieves status information without modification.

Get health check status for all virtual hosts. 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 get-health-virtual-hosts: 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.
get-health-virtual-hosts 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 get-health-virtual-hosts 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 get-health-virtual-hosts. 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.
