Get statistics about Celery workers.
AI agents call get_worker_stats to retrieve information from Celery MCP without modifying anything — typically the context-gathering step in research, monitoring, and reporting workflows, before the agent takes action elsewhere.
This tool retrieves monitoring data about worker status and performance metrics. It has no side effects, does not modify system state, does not execute tasks, and does not delete or create resources. It is a pure read operation, making it the lowest severity category.
From the tool's definition Tool name 'get_worker_stats' and description 'Get statistics about Celery workers' indicate a query/retrieval operation with no modification or execution capability.
Attacks that exploit this kind of access
Get statistics about Celery workers. It is categorised as a Read tool in the Celery MCP MCP Server, which means it retrieves data without modifying state.
Register the Celery MCP server in PolicyLayer and add a rule for get_worker_stats: 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 Celery MCP. Nothing to install.
get_worker_stats 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_worker_stats 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_worker_stats. 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.
get_worker_stats is provided by the Celery MCP server (joeyrubas/celery-mcp). PolicyLayer sits as a proxy in front of this server to enforce policies before tool calls reach the server.
