WHAT IT DOES

What login does on GeoGuessr MCP Server

AI agents use login to create or update resources in GeoGuessr MCP Server — usually the action step of a workflow, after the agent has gathered context. Every call changes real data in your GeoGuessr MCP Server environment.

WHY IT NEEDS A POLICY

Why login needs a policy

A 'login' tool typically submits credentials to authenticate a user, creating a session or token — a Write-level side effect (creates an auth session). However, the empty description lowers confidence. It could also be classified as Execute if it triggers external auth flows.

From the tool's definition Tool name is 'login'; description is empty or uninformative.

Verdict

login stays usable, but capped — an agent stuck in a loop can't make hundreds of changes a minute. Everything else on the server is denied unless you say otherwise.
