Retrieves a specific memo by its ID. Returns detailed memo information including content, metadata, and relationships.
AI agents call memo_get to retrieve information from Ninetn MCP Server 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 fetches and returns memo data based on an identifier. There are no side effects, no data modification, and no irreversible actions.
From the tool's definition Tool name 'memo_get' and description 'Retrieves a specific memo by its ID. Returns detailed memo information' indicate data retrieval with no modification or deletion.

Retrieves a specific memo by its ID. Returns detailed memo information including content, metadata, and relationships. It is categorised as a Read tool in the Ninetn MCP Server MCP Server, which means it retrieves data without modifying state.
Register the Ninetn MCP Server MCP server in PolicyLayer and add a rule for memo_get: 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 Ninetn MCP Server. Nothing to install.
memo_get 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 memo_get 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 memo_get. 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.
memo_get is provided by the Ninetn MCP Server MCP server (diatonic-codes/ninetn-mcp-server). PolicyLayer sits as a proxy in front of this server to enforce policies before tool calls reach the server.
