THE RISK

Critical Risk

Why monica_manage_activity needs a policy

Because the tool supports delete operations, which are irreversible, it must be classified under Destructive. The most severe applicable category wins over Write (create/update) and Read (list/inspect). Misuse by an AI agent could permanently delete activity/meeting/event records in the CRM, making severity high given the breadth of records potentially affected.

From the tool's definition 'List, inspect, create, update, or delete activities' — the tool explicitly supports delete operations on activity records

POLICY

How to control monica_manage_activity

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_activity:

policy.json

{
  "version": "1",
  "default": "deny",
  "hide": [
    "monica_manage_activity"
  ]
}

monica_manage_activity disappears from the agent's tool list entirely, and any attempt to call it is denied. The rest of the server keeps working.
