AI agents call delete_note_tag to permanently remove resources in GetNote MCP Server — typically in cleanup and lifecycle workflows. It does its job in a single call, and there is no undo.
This tool deletes a specific tag from a note. Deletion is irreversible (the tag association is removed), placing it in the Destructive category. Severity is medium since only a tag is removed, not the note itself, limiting the blast radius.

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