Get the logged-in user
AI agents call GET_CURRENT_USER to retrieve information from Travel Agent 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 information about the currently authenticated user. It performs a query operation with no destructive, financial, or code execution components. The data retrieved is already known to the authenticated user (their own account), making the impact scope minimal even if exposed to misuse.
From the tool's definition Tool name 'GET_CURRENT_USER' and description 'Get the logged-in user' indicate retrieval of user identity/profile data without modification or side effects.
Attacks that exploit this kind of access
Get the logged-in user. It is categorised as a Read tool in the Travel Agent MCP Server MCP Server, which means it retrieves data without modifying state.
Register the Travel Agent MCP Server MCP server in PolicyLayer and add a rule for GET_CURRENT_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 Travel Agent MCP Server. Nothing to install.
GET_CURRENT_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 GET_CURRENT_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 GET_CURRENT_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.
GET_CURRENT_USER is provided by the Travel Agent MCP Server MCP server (nxgnosis/travelagentmcp). PolicyLayer sits as a proxy in front of this server to enforce policies before tool calls reach the server.
