Find the shortest path between two entities in the knowledge graph. Returns the complete path, path length, and relationship details for each connection. Useful for discovering how concepts are related and understanding knowledge connections.
AI agents call find_entity_path 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 is a graph traversal and query tool that retrieves pre-existing relationship data from the knowledge graph. It performs no writes, deletions, or external executions—only navigation and read access to documented entity relationships. The blast radius of misuse is minimal (information disclosure only).
From the tool's definition Tool finds and returns 'the shortest path between two entities', 'path length', and 'relationship details' — purely retrieval operations with no modification or side effects.

Find the shortest path between two entities in the knowledge graph. Returns the complete path, path length, and relationship details for each connection. Useful for discovering how concepts are related and understanding knowledge connections. 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 find_entity_path: 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.
find_entity_path 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 find_entity_path 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 find_entity_path. 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.
find_entity_path 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.
