AI agents call reset_api_key to permanently remove resources in Mowen Notes MCP Server — typically in cleanup and lifecycle workflows. It does its job in a single call, and there is no undo.
Resetting an API key irreversibly invalidates the existing key, breaking all integrations and sessions that depend on it. This action cannot be undone — the old key is permanently destroyed and replaced. This qualifies as Destructive due to the irreversible nature of invalidating the existing credential.

PolicyLayer is an MCP gateway — it sits between your AI agents and Mowen Notes MCP Server, and nothing reaches the server without passing your rules. This is the rule we recommend for reset_api_key:
{
"version": "1",
"default": "deny",
"hide": [
"reset_api_key"
]
}reset_api_key disappears from the agent's tool list entirely, and any attempt to call it is denied. The rest of the server keeps working.
