AI agents call open_nodes to retrieve information from Remote Memory MCP Server without modifying anything — typically the context-gathering step in research, monitoring, and reporting workflows, before the agent takes action elsewhere.
This tool reads and returns specific named entities from the knowledge graph. It performs a lookup/query operation with no side effects. The Korean description confirms it is a read/retrieval operation. Low severity as it only exposes stored knowledge graph data.
From the tool's definition 조회합니다 (translates to 'retrieves/queries entities with specific names')

특정 이름의 엔티티들을 조회합니다. It is categorised as a Read tool in the Remote Memory MCP Server MCP Server, which means it retrieves data without modifying state.
Register the Remote Memory MCP Server MCP server in PolicyLayer and add a rule for open_nodes: 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 Remote Memory MCP Server. Nothing to install.
open_nodes 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 open_nodes 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 open_nodes. 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.
open_nodes is provided by the Remote Memory MCP Server MCP server (yeomyujun/remote-memory-mcp-server). PolicyLayer sits as a proxy in front of this server to enforce policies before tool calls reach the server.
