WHAT IT DOES

What strava_create_activity does on Strava MCP Server

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

WHY IT NEEDS A POLICY

Why strava_create_activity needs a policy

This tool creates new activity records in Strava, which is a reversible data modification operation. It does not delete, execute external commands, or move money. The severity is medium because an AI agent could create many spurious activity entries, cluttering a user's fitness log, but such entries can be deleted and the primary harm is data pollution rather than irreversible loss or financial impact.

From the tool's definition Tool name 'strava_create_activity' and description 'Create a manual activity entry' indicate creation of new data. The mention of 'activity:write scope' confirms write-level permissions are required.
