Why monica_manage_relationship needs a policy

The tool explicitly supports delete operations on contact relationships, which is irreversible data loss. Since the most severe applicable category must be chosen, and deletion of relationship records cannot be undone, this qualifies as Destructive. Misuse by an AI agent could silently remove relationship links between contacts across a CRM instance.

POLICY

How to control monica_manage_relationship

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_relationship:

policy.json

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

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