Discover entities related to a given entity (simplified version of get_entity_relationships). Returns top related entities for quick exploration and discovery.
AI agents call find_related_entities 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 and queries relationship data from an existing knowledge base without side effects. The verb 'discover' indicates a read-only search operation. No data is created, modified, deleted, or executed. The low blast radius reflects minimal risk if misused by an AI agent—it can only expose existing entity relationships within the Commodore 64 documentation index.
From the tool's definition Tool performs 'discover' and 'returns' operations for entity relationships without modification. The description emphasizes 'exploration and discovery' with no mention of data creation, modification, deletion, or external execution.
Attacks that exploit this kind of access
Discover entities related to a given entity (simplified version of get_entity_relationships). Returns top related entities for quick exploration and discovery. 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_related_entities: 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_related_entities 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_related_entities 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_related_entities. 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_related_entities 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.
