Zerion API MCP

Model Context Protocol (MCP) server

Connect Claude, Cursor, and other AI coding tools to the Zerion API docs through the Model Context Protocol server for in-editor answers and code generation.

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

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.

Open the command palette (`Cmd+Shift+P`) → "MCP: Edit Config", then add:

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

Create `.vscode/mcp.json` in your project:

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

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

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:

Paste any docs page URL into Claude for API questions and code generation. Use ChatGPT to explore endpoints and generate integration code. 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.
