# MCP Server Overview

## What you can do with it

Drawing from our patented identity graph, the MCP Server empowers your AI agents to:

- **Resolve a person from a single identifier.** Pass an email, phone number, social profile, or name + postal address and receive a unified person profile.
- **Enrich CRM and marketing workflows.** Let an agent watch new signups, leads, or support tickets and append demographic, employment, and social data on the fly.
- **Power conversational research.** Ask your IDE assistant or chatbot, "Who is this person, and where do they work?" and get a structured answer grounded in FullContact data.
- **Stay inside your existing controls.** All calls are authenticated with your FullContact API key and counted against your normal rate limits and billing plan.

## How it works

1. The AI client discovers the server's tool catalog and JSON Schema for `enrich_person`.
2. When the agent decides to enrich a person, it sends an MCP request through the configured client.
3. The MCP Server validates your API key, applies your account's rate limits, and forwards the request to `person.enrich`.
4. The response is normalized into a compact, agent-friendly JSON payload and returned to the client.
