rmq_health_check
AI agents call rmq_health_check 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.
Health checks are non-destructive diagnostic reads that query system state without modifying data or executing arbitrary code. The naming pattern and context suggest this retrieves health status information. Severity is low because health checks have minimal blast radius—they cannot modify state, execute code, or cause financial impact.
From the tool's definition Tool name 'rmq_health_check' indicates a health check operation, which is a monitoring/query activity. The '_health_check' suffix appears on sibling tools (argocd_health_check, aws_health_check) that are clearly Read operations.
Attacks that exploit this kind of access
rmq_health_check. 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_health_check: 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_health_check 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_health_check 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_health_check. 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_health_check 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.
