# MCP

> Connect your AI tools to the Zerion API docs via Model Context Protocol.

The Zerion API docs are available as a Model Context Protocol (MCP) server. Once connected, your AI tool can search our full documentation and OpenAPI spec while generating code — no copy-pasting needed.

## Connect via MCP

<Tabs>
  <Tab title="Claude Code">
    Run this in your terminal:

    ```bash theme={null}
    claude mcp add --transport http zerion-api https://developers.zerion.io/mcp
    ```

    The Zerion docs will be available as a tool in all Claude Code sessions.
  </Tab>

  <Tab title="Cursor">
    Open the command palette (`Cmd+Shift+P`) → "MCP: Edit Config", then add:

    ```json theme={null}
    {
      "mcpServers": {
        "zerion-api": {
          "url": "https://developers.zerion.io/mcp"
        }
      }
    }
    ```
  </Tab>

  <Tab title="VS Code">
    Create `.vscode/mcp.json` in your project:

    ```json theme={null}
    {
      "servers": {
        "zerion-api": {
          "type": "http",
          "url": "https://developers.zerion.io/mcp"
        }
      }
    }
    ```
  </Tab>

  <Tab title="Claude Web">
    1. Go to Claude settings → **Connectors**
    2. Select **Add custom connector**
    3. Name: `Zerion API`, URL: `https://developers.zerion.io/mcp`
    4. Use the attachments button (+) in any chat to access it
  </Tab>
</Tabs>

## What you can ask

Once connected, you can ask your AI assistant things like:

* *"How do I get a wallet's token positions on Ethereum?"*
* *"Write a Python script that fetches transaction history and filters for trades"*
* *"What filters are available on the positions endpoint?"*

The AI will search the Zerion docs in real-time to give you accurate, up-to-date answers.

## Open in AI assistants

You can also open any documentation page directly in an AI chat for quick questions:

<CardGroup cols={2}>
  <Card title="Claude" icon="message" href="https://claude.ai">
    Paste any docs page URL into Claude for API questions and code generation.
  </Card>

  <Card title="ChatGPT" icon="message" href="https://chat.openai.com">
    Use ChatGPT to explore endpoints and generate integration code.
  </Card>
</CardGroup>

<Tip>
  For the best experience, use the MCP integration instead of copy-pasting. It gives the AI access to the full docs and API spec, not just one page at a time.
