Why get_new_contacts needs a policy

This tool retrieves or queries contact data without modifying, deleting, or executing any operations. It is a simple data retrieval endpoint analogous to filtering a database for uncontacted leads. The verb 'Retrieve' and the absence of any modification, deletion, or execution language confirm this is a Read category tool with low severity.

From the tool's definition Tool name 'get_new_contacts' and description 'Retrieve contacts that have NOT received any messages yet' indicate a read-only query operation with no side effects.

POLICY

How to control get_new_contacts

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

policy.json

{
  "version": "1",
  "default": "deny",
  "tools": {
    "get_new_contacts": {}
  }
}

get_new_contacts is read-only, so it stays allowed — but everything else on the server is denied unless you say otherwise.

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