Resolve entity references like
AI agents call entity_resolve to retrieve information from MCP Memory Server without modifying anything — typically the context-gathering step in research, monitoring, and reporting workflows, before the agent takes action elsewhere.
Entity resolution is a read/lookup operation that maps ambiguous references to known entities in the memory store. No side effects are implied by resolution. Confidence is reduced due to the truncated description, but the operation appears to be a query against stored data rather than a write or destructive action.
From the tool's definition Tool name 'entity_resolve' suggests resolving/looking up entity references; description is truncated and uninformative beyond 'Resolve entity references like'
Attacks that exploit this kind of access
Resolve entity references like. It is categorised as a Read tool in the MCP Memory Server MCP Server, which means it retrieves data without modifying state.
Register the MCP Memory Server MCP server in PolicyLayer and add a rule for entity_resolve: 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 MCP Memory Server. Nothing to install.
entity_resolve 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 entity_resolve 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 entity_resolve. 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.
entity_resolve is provided by the MCP Memory Server MCP server (plumycat/mcp-memory-server). PolicyLayer sits as a proxy in front of this server to enforce policies before tool calls reach the server.
