## Example call (MCP tools/call, JSON-RPC 2.0)

```json
{
  "jsonrpc": "2.0",
  "id": 1,
  "method": "tools/call",
  "params": {
    "name": "config_unset",
    "arguments": {}
  }
}
```

## Why config_unset is rated Critical

This tool removes (clears) a configuration value, which is a destructive operation that cannot be undone without knowing the original value. Misuse could break API authentication or connectivity by wiping critical config values like API keys or credentials. Severity is medium since it affects configuration rather than data, but could disrupt all Kaggle API operations.

From the tool's own definition: "'Clear a Kaggle API configuration value' — clearing/unsetting configuration is an irreversible removal of a stored value"

## Use case

AI agents call config_unset 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.

## Recommended policy (PolicyLayer)

Verdict: **Hidden**. Enforced by the PolicyLayer MCP gateway (https://policylayer.com/mcp-gateway) before a call reaches Kaggle-MCP:

```json
{
  "version": "1",
  "default": "deny",
  "hide": [
    "config_unset"
  ]
}
```
