What model_instance_delete does on Kaggle-MCP
AI agents call model_instance_delete to permanently remove resources in Kaggle-MCP, typically in cleanup and lifecycle workflows. It does its job in a single call, and there is no undo.
Why model_instance_delete is rated Critical
Deletion operations that cannot be undone fall under the Destructive category. Deleting a model instance permanently removes it from the Kaggle platform, which is a non-recoverable action. The high severity reflects that an AI agent misusing this tool could irretrievably destroy a user's trained models or work products. Confidence is high because the intent is unambiguous.
From the tool's definition Tool name includes 'delete' and description states 'Delete a model instance' — this is an irreversible removal operation.
Attacks that exploit this kind of access
The rule that runs model_instance_delete 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 model_instance_delete, this is the rule to start with:
model_instance_delete is removed from the agent's tool list entirely, so the agent never calls it. The rest of the server keeps working.
The button opens the PolicyLayer dashboard: create your workspace, connect Kaggle-MCP, apply this rule, and every model_instance_delete call is checked against it from then on.
Questions about model_instance_delete
Delete a model instance. It is categorised as a Destructive tool in the Kaggle-MCP MCP Server, which means it can permanently delete or destroy data. Block by default and require explicit approval.
Register the Kaggle MCP server in PolicyLayer and add a rule for model_instance_delete: allow, deny, rate-limit, or require approval. Point your MCP client at the PolicyLayer proxy URL and the rule is enforced on every call, before it reaches Kaggle-MCP. Nothing to install.
model_instance_delete is a Destructive tool with critical risk. Critical-risk tools should be blocked by default and only enabled with explicit human approval.
Yes. Add a rate_limit block to the model_instance_delete rule in your PolicyLayer policy. For example, setting max: 10 and window: 60 limits the tool to 10 calls per minute. Rate limits are tracked per agent session and reset automatically.
Set action: deny in the PolicyLayer policy for model_instance_delete. The AI agent will receive a policy violation error and cannot call the tool. You can also include a reason field to explain why the tool is blocked.
model_instance_delete is provided by the Kaggle MCP server (54yyyu/kaggle-mcp). PolicyLayer sits as a proxy in front of this server to enforce policies before tool calls reach the server.
