Bulk extract entities from multiple documents in the knowledge base. Processes documents in batch, skips documents that already have entities (unless force_regenerate). Returns statistics about processed documents and extracted entities.
AI agents call extract_entities_bulk 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.
This tool performs entity extraction and analysis on existing documents, which is a read-only operation. It processes documents in batch and returns results (statistics and extracted entities) without creating new documents, deleting documents, or executing arbitrary code. Even with force_regenerate, it re-analyzes rather than modifies document content.
From the tool's definition Tool description indicates it 'extract[s] entities from multiple documents' and 'returns statistics about processed documents'.
Attacks that exploit this kind of access
Bulk extract entities from multiple documents in the knowledge base. Processes documents in batch, skips documents that already have entities (unless force_regenerate). Returns statistics about processed documents and extracted entities. 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 extract_entities_bulk: 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.
extract_entities_bulk 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 extract_entities_bulk 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 extract_entities_bulk. 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.
extract_entities_bulk 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.
