Retrieve a specific user by user_id in Notion. Note: This function requires upgrading to the Notion Enterprise plan and using an Organization API key to avoid permission errors.
AI agents call notion_retrieve_user to retrieve information from Notion MCP Server without modifying anything — typically the context-gathering step in research, monitoring, and reporting workflows, before the agent takes action elsewhere.
The tool retrieves user information by ID. It performs a read-only query operation without creating, modifying, deleting, or executing any actions. The requirement for Enterprise plan access and Organization API key indicates it accesses potentially sensitive user data, but retrieval alone constitutes a Read operation.
From the tool's definition Tool description states 'Retrieve a specific user by user_id in Notion' — a retrieval operation with no modification or side effects.

Retrieve a specific user by user_id in Notion. Note: This function requires upgrading to the Notion Enterprise plan and using an Organization API key to avoid permission errors. It is categorised as a Read tool in the Notion MCP Server MCP Server, which means it retrieves data without modifying state.
Register the Notion MCP Server MCP server in PolicyLayer and add a rule for notion_retrieve_user: 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 Notion MCP Server. Nothing to install.
notion_retrieve_user 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 notion_retrieve_user 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 notion_retrieve_user. 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.
notion_retrieve_user is provided by the Notion MCP Server MCP server (tkc/notion-mcp). PolicyLayer sits as a proxy in front of this server to enforce policies before tool calls reach the server.
