POLICY

How to control CiviCRM MCP Server

PolicyLayer is an MCP gateway — it sits between your AI agents and CiviCRM MCP Server, and nothing reaches the server without passing your rules. These are the rules we recommend:

Deny destructive operations
{
  "delete_address": {
    "deny_if": [
      {
        "conditions": [],
        "on_deny": "Blocked by default. Requires approval."
      }
    ]
  }
}

Destructive tools should never be available to autonomous agents without human approval.

Rate limit write operations
{
  "add_contact_to_group": {
    "limits": [
      {
        "counter": "add_contact_to_group_per_hour",
        "window": "hour",
        "max": 30,
        "scope": "grant"
      }
    ]
  }
}

Prevents bulk unintended modifications from agents caught in loops.

Cap read operations
{
  "get_activities": {
    "limits": [
      {
        "counter": "get_activities_per_minute",
        "window": "minute",
        "max": 60,
        "scope": "grant"
      }
    ]
  }
}

Controls API costs and prevents retry loops from exhausting upstream rate limits.

  1. Create a free account and register CiviCRM MCP Server — nothing to install.
  2. Add these rules — paste them, or build them visually. Tune the limits to your setup.
  3. Point your MCP client (Claude, Cursor, anything) at your gateway URL.

FAQ

Questions about CiviCRM MCP Server

Can an AI agent delete data through the CiviCRM MCP Server MCP server? +

Yes. The CiviCRM MCP Server server exposes 6 destructive tools including delete_address, delete_email, delete_phone. These permanently remove resources with no undo. PolicyLayer blocks destructive tools by default so they never reach the upstream server.

How do I prevent bulk modifications through CiviCRM MCP Server? +

The CiviCRM MCP Server server has 14 write tools including add_contact_to_group, add_entity_tag, create_activity. Set a rate limit in your policy -- for example, 10 calls per hour prevents an agent from making more than 10 modifications per hour. PolicyLayer enforces this at the gateway, before calls reach CiviCRM MCP Server.

How many tools does the CiviCRM MCP Server MCP server expose? +

48 tools across 3 categories: Destructive, Read, Write. 28 are read-only. 20 can modify, create, or delete data.

How do I enforce a policy on CiviCRM MCP Server? +

Register the CiviCRM MCP Server MCP server in PolicyLayer, apply the suggested rules above (adjust the limits to your use case), and point your AI client at the PolicyLayer proxy URL instead of the server directly. Your agents keep the same tools; PolicyLayer evaluates every call against policy before it executes. Nothing to install, live in minutes.
