AI agents call get_phone_number to retrieve information from GoHighLevel MCP Server without modifying anything — typically the context-gathering step in research, monitoring, and reporting workflows, before the agent takes action elsewhere.
This tool retrieves an existing phone number record using an identifier. It performs a simple query operation without creating, modifying, deleting, or executing any actions. The 'get' verb and retrieval-only description clearly indicate a Read category classification.

PolicyLayer is an MCP gateway — it sits between your AI agents and GoHighLevel MCP Server, and nothing reaches the server without passing your rules. This is the rule we recommend for get_phone_number:
{
"version": "1",
"default": "deny",
"tools": {
"get_phone_number": {}
}
}get_phone_number is read-only, so it stays allowed — but everything else on the server is denied unless you say otherwise.
