# Claude Code plugin

> Connect Crustdata to Claude Code with one command: MCP data tools covering 800M+ people profiles and 200M+ companies, ready-to-run skills, and one sign-in.

The Crustdata plugin for Claude Code bundles the [MCP server](/for-agents/mcp) and ready-to-run skills into a single install. One command adds the data tools (800M+ people profiles and 200M+ companies) and the skills; sign in once and you're set.

<Note>
  This installs Crustdata in **Claude Code**. For **Claude.ai** or **Claude Desktop**, add the [MCP connector](/for-agents/mcp) instead.
</Note>

* **One command to install.** The data tools and the skills come together, no config to hand-write.
* **Skills, ready to run.** They install with the plugin and appear under the `/crustdata` namespace.
* **Sign in once.** No API key to copy or paste; the tools and the skills share a single sign-in.

## Quick start

<Steps>
  <Step title="Install the plugin">
    Add the Crustdata marketplace and install the plugin:

    ```bash theme={"theme":"vitesse-black"}
    claude plugin marketplace add crustdata/skills
    claude plugin install crustdata@crustdata-plugin
    ```

    This adds the Crustdata MCP server and the skills.
  </Step>

  <Step title="Sign in">
    Run **`/crustdata:login`** and your browser opens for a one-time sign-in, no key to paste. Until you sign in, Crustdata tool calls simply point you at the command; nothing nags you at session start.

    Prefer a key? Set `CRUSTDATA_API_KEY` in your environment instead and skip the sign-in.

## Sign-in

Run **`/crustdata:login`** to sign in with your Crustdata account. It's a one-time browser sign-in, no API key to copy or paste. The data tools and the skills share that single sign-in, tokens refresh silently, and if it ever expires a Crustdata tool call points you back at the command. `CRUSTDATA_API_KEY` works as an override if you'd rather pass a key directly.
