Why get_person_email needs a policy

This tool retrieves contact information (email address) indexed by Apollo ID. It performs no mutation, deletion, execution, or financial transaction. The email address itself is typically non-sensitive business contact data in a B2B sales/enrichment context. Blast radius is minimal: exposure of this data affects targeted contact lists but does not authorize spending, code execution, or destructive actions.

From the tool's definition Tool description states 'Get email address for a person' — a retrieval operation with no modification or side effects. The verb 'Get' and the context (enrichment/search operations on a data platform) indicate query-only functionality.

POLICY

How to control get_person_email

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 get_person_email:

policy.json

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

get_person_email 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.
