Get statistics about extracted entities in the knowledge base. Shows breakdown by type, top entities, and documents with most entities. Useful for understanding the knowledge base content.
AI agents call entity_stats to retrieve information from TDZ C64 Knowledge without modifying anything — typically the context-gathering step in research, monitoring, and reporting workflows, before the agent takes action elsewhere.
entity_stats retrieves and aggregates statistics from already-indexed entity data. It has no side effects, cannot modify the knowledge base, trigger external operations, or delete information. The blast radius of misuse is minimal; an attacker could only learn about the knowledge base structure and content distribution, which presents no data exfiltration risk beyond what read access already allows.
From the tool's definition Tool provides statistical queries about extracted entities: 'breakdown by type, top entities, and documents with most entities.' No modification, deletion, execution of external operations, or financial action is performed—purely retrieval and analysis of…

Get statistics about extracted entities in the knowledge base. Shows breakdown by type, top entities, and documents with most entities. Useful for understanding the knowledge base content. It is categorised as a Read tool in the TDZ C64 Knowledge MCP Server, which means it retrieves data without modifying state.
Register the TDZ C64 Knowledge MCP server in PolicyLayer and add a rule for entity_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 TDZ C64 Knowledge. Nothing to install.
entity_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 entity_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 entity_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.
entity_stats is provided by the TDZ C64 Knowledge MCP server (michaeltroelsen/tdz-c64-knowledge). PolicyLayer sits as a proxy in front of this server to enforce policies before tool calls reach the server.
Every MCP server has a record like this.
