Get all entities related to a specific entity. Shows which other entities frequently co-occur with the target entity, sorted by relationship strength. Great for discovering related concepts, hardware, and techniques.
AI agents call get_entity_relationships 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 a read-only query operation that returns relationship data from the knowledge base. It has no side effects—it does not create, modify, delete, or execute anything. The blast radius of misuse is minimal; an agent cannot harm data or systems by querying entity relationships. It belongs in the Read category with low severity.
From the tool's definition The tool "get_entity_relationships" retrieves relationships between entities and shows co-occurrence data "sorted by relationship strength." The verb "Get" and "Shows" indicate data retrieval with no modification.

Get all entities related to a specific entity. Shows which other entities frequently co-occur with the target entity, sorted by relationship strength. Great for discovering related concepts, hardware, and techniques. 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 get_entity_relationships: 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.
get_entity_relationships 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 get_entity_relationships 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 get_entity_relationships. 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.
get_entity_relationships 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.
