AI agents call get_note to retrieve information from NestJS MCP Server without modifying anything — typically the context-gathering step in research, monitoring, and reporting workflows, before the agent takes action elsewhere.
This tool retrieves or queries stored note data without side effects, making it a Read operation. The low severity reflects that unauthorized access to user notes poses minimal blast radius compared to destructive or financial operations, though context-dependent sensitivity of note content could marginally increase risk in specific deployments.
From the tool's definition Tool name 'get_note' and description indicating retrieval of saved notes ('保存されたメモを取得します' = 'Get saved notes'). No modification, deletion, or execution occurs.

Register the NestJS MCP Server MCP server in PolicyLayer and add a rule for get_note: 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 NestJS MCP Server. Nothing to install.
get_note 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_note 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_note. 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_note is provided by the NestJS MCP Server MCP server (kaz29/mcp-server-example). PolicyLayer sits as a proxy in front of this server to enforce policies before tool calls reach the server.
