List all users in the Notion workspace. Note: This function requires upgrading to the Notion Enterprise plan and using an Organization API key to avoid permission errors.
AI agents call notion_list_all_users 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.
This is a read-only operation that queries and returns user data from a Notion workspace. While it retrieves potentially sensitive information (workspace user identities and membership), it does not create, modify, delete, or execute operations.
From the tool's definition Tool name and description indicate it "List[s] all users in the Notion workspace" — a query operation that retrieves user data without modifying, deleting, or executing code. The description explicitly states it retrieves user information.

List all users in the Notion workspace. 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_list_all_users: 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_list_all_users 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_list_all_users 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_list_all_users. 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_list_all_users is provided by the Notion MCP Server MCP server (kimjungyeol/mcp-notion-server). PolicyLayer sits as a proxy in front of this server to enforce policies before tool calls reach the server.
