Get task queue statistics (pending, running, completed, failed counts).
AI agents call get_queue_stats to retrieve information from Code Graph Knowledge System without modifying anything — typically the context-gathering step in research, monitoring, and reporting workflows, before the agent takes action elsewhere.
The tool only queries and returns statistics about the current state of task queues. It does not modify, delete, execute, or trigger any operations. It is a read-only diagnostic query with minimal blast radius if misused by an AI agent—worst case being misleading information about queue status used for decision-making, but no actual system changes result from calling this tool.
From the tool's definition Tool name is 'get_queue_stats' and description states it retrieves 'task queue statistics (pending, running, completed, failed counts)'. This is a pure information retrieval operation with no side effects.
Documented attack patterns abuse exactly the kind of access get_queue_stats gives an agent:
PolicyLayer is an MCP gateway — it sits between your AI agents and Code Graph Knowledge System, and nothing reaches the server without passing your rules. This is the rule we recommend for get_queue_stats:
{
"version": "1",
"default": "deny",
"tools": {
"get_queue_stats": {}
}
}get_queue_stats is read-only, so it stays allowed — but everything else on the server is denied unless you say otherwise.

Get task queue statistics (pending, running, completed, failed counts). It is categorised as a Read tool in the Code Graph Knowledge System MCP Server, which means it retrieves data without modifying state.
Register the Code Graph Knowledge System MCP server in PolicyLayer and add a rule for get_queue_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 Code Graph Knowledge System. Nothing to install.
get_queue_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_queue_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_queue_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_queue_stats is provided by the Code Graph Knowledge System MCP server (royisme/codebase-rag). PolicyLayer sits as a proxy in front of this server to enforce policies before tool calls reach the server.
Start from Code Graph Knowledge System, add the rest of your stack, and see everything your agents can call. Then put policy on all of it.
Free to start. No card required.
