Find documents that contain both entities. Useful for finding documentation about specific combinations (e.g.,
AI agents call search_entity_pair 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 retrieves or queries existing documentation to find records matching specified entity pairs. It has no side effects, does not create, modify, or delete data, and does not execute code or external operations. It is a straightforward search/query function typical of knowledge base systems. Severity is low because misuse by an AI agent would only return unwanted search results, with no harmful consequences.
From the tool's definition Tool name 'search_entity_pair' and description 'Find documents that contain both entities' indicate a query/search operation with no modification or execution of code.

Find documents that contain both entities. Useful for finding documentation about specific combinations (e.g.,. 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 search_entity_pair: 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.
search_entity_pair 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 search_entity_pair 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 search_entity_pair. 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.
search_entity_pair 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.
