Why monica_manage_note needs a policy

While the tool includes a delete operation (which would suggest Destructive category), delete is described as one of several note management functions alongside create and update, indicating it is a reversible data management operation rather than the tool's primary purpose. Notes are user-created journal entries that can typically be restored from backups or recreated.

From the tool's definition Tool description states it can 'create, update, or delete notes' — the delete operation is a destructive capability, but the tool's primary documented use is managing (listing, inspecting, creating, updating) notes as reversible operations.

How to control monica_manage_note

PolicyLayer is an MCP gateway — it sits between your AI agents and Monica CRM MCP Server, and nothing reaches the server without passing your rules. This is the rule we recommend for monica_manage_note:

policy.json

{
  "version": "1",
  "default": "deny",
  "tools": {
    "monica_manage_note": {
      "limits": [
        {
          "counter": "monica_manage_note_rate",
          "window": "minute",
          "max": 30,
          "scope": "grant"
        }
      ]
    }
  }
}

monica_manage_note stays usable, but capped — an agent stuck in a loop can't make hundreds of changes a minute. Everything else on the server is denied unless you say otherwise.
