What competition_leaderboard does on Kaggle-MCP
AI agents call competition_leaderboard to retrieve information from Kaggle-MCP without modifying anything. It is typically the context-gathering step in research, monitoring, and reporting workflows, before the agent takes action elsewhere.
Why competition_leaderboard is rated Low
This tool performs a read-only operation—fetching and displaying competition leaderboard information. It has no side effects, does not create, modify, or delete data, and does not execute code or trigger financial transactions. The blast radius of misuse is minimal; an agent retrieving leaderboard data cannot cause harm beyond potentially accessing information it should not see (a lower-severity read concern).
From the tool's definition Tool name 'competition_leaderboard' and description 'Get the competition leaderboard' indicate a retrieval operation that queries and returns existing leaderboard data without modification.
Attacks that exploit this kind of access
The rule that runs competition_leaderboard safely
PolicyLayer is an MCP gateway: it sits between your AI agents and Kaggle-MCP, and checks every tool call against a rule you set before the call runs. Nothing changes on the server itself. For competition_leaderboard, this is the rule to start with:
competition_leaderboard is read-only, so it stays allowed. Everything else on the server is denied unless you say otherwise.
The button opens the PolicyLayer dashboard: create your workspace, connect Kaggle-MCP, apply this rule, and every competition_leaderboard call is checked against it from then on.
