What find_shortest_path does on Enhanced Knowledge Graph Memory Server
AI agents call find_shortest_path to retrieve information from Enhanced Knowledge Graph Memory Server without modifying anything. It is typically the context-gathering step in research, monitoring, and reporting workflows, before the agent takes action elsewhere.
Why find_shortest_path is rated Low
This tool performs graph traversal to discover connections between entities. It is a retrieval operation with no side effects—it does not create, modify, delete, execute code, or perform financial operations. The operation is deterministic and dependent only on the existing graph structure.
From the tool's definition Tool name 'find_shortest_path' and description 'Find the shortest path between two entities in the knowledge graph' indicate a query operation that retrieves information about relationships in the knowledge graph without modifying, deleting, or executing…
Attacks that exploit this kind of access
The rule that runs find_shortest_path safely
PolicyLayer is an MCP gateway: it sits between your AI agents and Enhanced Knowledge Graph Memory Server, and checks every tool call against a rule you set before the call runs. Nothing changes on the server itself. For find_shortest_path, this is the rule to start with:
find_shortest_path is read-only, so it stays allowed. Everything else on the server is denied unless you say otherwise.
The button opens the PolicyLayer dashboard: create your workspace, connect Enhanced Knowledge Graph Memory Server, apply this rule, and every find_shortest_path call is checked against it from then on.
Questions about find_shortest_path
Find the shortest path between two entities in the knowledge graph. It is categorised as a Read tool in the Enhanced Knowledge Graph Memory Server MCP Server, which means it retrieves data without modifying state.
Register the Enhanced Knowledge Graph Memory Server MCP server in PolicyLayer and add a rule for find_shortest_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 Enhanced Knowledge Graph Memory Server. Nothing to install.
find_shortest_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_shortest_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_shortest_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_shortest_path is provided by the Enhanced Knowledge Graph Memory Server MCP server (danielsimonjr/memory-mcp). PolicyLayer sits as a proxy in front of this server to enforce policies before tool calls reach the server.
