Why remove_contacts_from_list needs a policy

The tool removes contacts from a list, which is a destructive operation. While it may not permanently delete the contacts themselves, removing them from a list is typically not automatically reversible and could disrupt workflows, communications, or segmentation that depends on list membership. Given the context of a customer communication platform, bulk removal could have significant operational impact.

From the tool's definition 'Remove contacts from a contact list' - removing contacts from a list is a deletion/removal action that may not be easily reversible

POLICY

How to control remove_contacts_from_list

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

policy.json

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

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

Create a free account and register Frontapp MCP Server — nothing to install.
Add this policy — paste it, or build it visually.
Point your MCP client (Claude, Cursor, anything) at your gateway URL.
