Retrieve the current user.
AI agents call retrieve_self 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 tool performs a read-only operation to retrieve the authenticated user's identity. It has no side effects, does not modify data, and does not execute code or trigger external operations. The blast radius is minimal—at worst, an agent learns who the authenticated user is. This is a standard informational query.
From the tool's definition Tool name 'retrieve_self' and description 'Retrieve the current user' indicate a query operation that fetches user identity information without modifying, deleting, or executing operations.
Attacks that exploit this kind of access
Retrieve the current user. 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 retrieve_self: 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.
retrieve_self 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 retrieve_self 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 retrieve_self. 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.
retrieve_self is provided by the Notion MCP Server MCP server (lrgex/notion-mcp). PolicyLayer sits as a proxy in front of this server to enforce policies before tool calls reach the server.
