# MCP Server

> Connect Crustdata's B2B data platform to Claude and other AI assistants via MCP (Model Context Protocol).

The Crustdata MCP server gives AI assistants direct access to 800M+ professional profiles and 200M+ companies. Connect it to Claude.ai, Claude Code, Cursor, or any MCP-compatible client and search, enrich, and analyze B2B data through natural language.

<Note>
  **New** — this is our latest MCP server, and we'd love for you to try it.
</Note>

* **Ask in plain English.** No query language, no endpoints to learn — just describe what you want.
* **Complex asks, one step.** A request like *"find AI startups hiring engineers, then get me the founders' emails"* runs start to finish in a single step.
* **Know the cost, instantly.** Every request reports the exact credits it spent, in real time — no surprises.
* **Connect in seconds.** Sign in with your Crustdata account — there's no API key to copy or paste.

## Cost transparency

Every request reports the **exact credits it spent, in real time** — measured from what the request actually did, never estimated. Enrichment always takes the cheapest correct path, so you never over-spend by accident.

## Sign-in

Sign in with your Crustdata account when you connect — there's **no API key to copy or paste**. Your key is never stored, and you can disconnect any time from your MCP client.

## Common workflows

**Research a company** — identify the company, enrich it with the fields you care about, and check its recent social activity.

**Find decision-makers** — search people by company, seniority, and title, then enrich for contact info.

**Hiring analysis** — search jobs by company, title, and location, and break the results down by category or location.

**Competitive intelligence** — compare openings across competitors and track their social activity.
