Why employees_of_company needs a policy

This is a read operation that queries Apollo.io's enrichment API to fetch employee information. No data is created, modified, deleted, or executed. The blast radius is minimal since it only exposes publicly available employee data, with no ability to manipulate systems or commit financial obligations.

From the tool's definition Tool description states 'Find employees of a company' — a retrieval operation. The method verb is passive (find/retrieve), with no modification, deletion, or execution of code mentioned. Returns company personnel data without side effects.

POLICY

How to control employees_of_company

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

policy.json

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

employees_of_company 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 Apollo Io 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.
