WHY IT NEEDS A POLICY

Why set_cursor_api_key_tool needs a policy

Setting an API key is a write operation that creates or modifies stored credentials. While not destructive (the key can be changed), it has high severity because a compromised or incorrectly set API key could grant unauthorized access to external services or break legitimate API connections. This is a state-modifying operation without data deletion, placing it in Write rather than Execute or Destructive.

From the tool's definition Tool name 'set_cursor_api_key_tool' indicates it sets or stores an API key. The empty description prevents full certainty, but the function clearly modifies configuration/credential state.
