log_workout · MCP Logger MCP: Risk & Policy

WHAT IT DOES

What log_workout does on MCP Logger

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

WHY IT NEEDS A POLICY

Why log_workout needs a policy

The name 'log_workout' strongly implies writing a new workout record to the local SQLite database, consistent with the server's purpose of logging fitness data. Sibling tools like 'add_exercise' and 'add_set' confirm this server has write-oriented logging tools. However, the empty description lowers confidence — it could also involve broader operations.

From the tool's definition Tool name 'log_workout' suggests creating/recording a workout entry; description is empty and uninformative.
