WHAT IT DOES

What competition_submit does on Kaggle-MCP

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

WHY IT NEEDS A POLICY

Why competition_submit needs a policy

Submitting to a competition creates a new record (a submission) on Kaggle's platform. This is a Write operation as it posts data to an external service. It is reversible in the sense that submissions can be made multiple times, though each submission counts against any submission limits.

From the tool's definition 'Submit to a competition' — creates a new submission entry in a Kaggle competition

Verdict

competition_submit Rate-limited

competition_submit 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.
