Get the authenticated user\
AI agents call get_user_checkins to retrieve information from Untappd 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 checkin data for the authenticated user from the Untappd API. It performs a query operation with no side effects—it does not create, modify, delete, or execute any operations. It simply fetches existing data. The low severity reflects minimal blast radius if misused; an agent could retrieve user checkin history but cannot modify or delete data, execute commands, or commit financial transactions.
From the tool's definition Tool name 'get_user_checkins' and description 'Get the authenticated user' indicate data retrieval. The Untappd MCP Server is described as allowing Claude to 'query' and 'retrieve' information from the beer database API, which are read-only operations.

Get the authenticated user\. It is categorised as a Read tool in the Untappd MCP Server MCP Server, which means it retrieves data without modifying state.
Register the Untappd MCP Server MCP server in PolicyLayer and add a rule for get_user_checkins: 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 Untappd MCP Server. Nothing to install.
get_user_checkins 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_user_checkins 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_user_checkins. 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_user_checkins is provided by the Untappd MCP Server MCP server (jtucker/mcp-untappd-server). PolicyLayer sits as a proxy in front of this server to enforce policies before tool calls reach the server.
