description: Connect AI tools to 0x documentation for an enhanced development experience.
-----------------------------------------------------------------------------------------

The **0x MCP Server** gives AI tools live, searchable access to 0x documentation using the [Model Context Protocol (MCP)](https://modelcontextprotocol.io/).

Instead of copy-pasting documentation into prompts, your AI assistant can retrieve the right guides, API references, and examples automatically.

**The server is hosted at**

`https://docs.0x.org/_mcp/server`

Once connected, you can describe what you're building and your AI tool will pull the relevant documentation into context.

#### What you can do with MCP

After connecting, search the full 0x documentation. Ask questions like:

> "How do I generate a swap quote?"\
> "What parameters are required for a Gasless API request?"\
> "Which chains does 0x support?"

Your AI assistant searches the documentation and returns relevant sections automatically.

#### Generate implementation-ready code

Start with your goal:

> "I'm building a swap feature on Base in TypeScript."

The AI retrieves the appropriate documentation and generates structured implementation code based on official 0x guides.

***

#### Debug integration issues

Ask:

> "Why am I getting a 400 error from the 0x API?"\
> "My quote succeeds but the transaction reverts — what should I check?"

The AI searches troubleshooting sections and surfaces likely causes.

### Best practices for prompting

* Start with what you're building, not the endpoint name.
* Mention your chain and language.
* Ask for examples first.
* Iterate on the returned code.

  <Tab title="Automatic (Recommended)">
    The fastest way to connect MCP to Cursor.

    <Steps>
      <Step title="Connect to Cursor">
        On any CDP documentation page, open the **Copy page** dropdown next to the page header.\
        Select **Connect to Cursor**.\
        Cursor will automatically open with the CDP MCP server configured.
      </Step>

      <Step title="Test the connection">
        In Cursor’s chat, ask: **“What tools do you have available?”**

        Cursor should confirm access to 0x documentation search and configured API endpoints.
      </Step>
    </Steps>
  </Tab>

  <Tab title="Manual configuration">
    Use this option if you prefer explicit setup or need to troubleshoot.

    <Steps>
      <Step title="Open MCP settings">
        Open Cursor and press `Cmd + Shift + P` (`Ctrl + Shift + P` on Windows).\
        Search for **Open MCP settings**.\
        Select **Open MCP settings** to open `mcp.json`.
      </Step>

      <Step title="Configure the CDP server">
        Add the following configuration to `mcp.json`:

        ```json title="mcp.json"
        {
          "mcpServers": {
            "0x": {
              "url": "https://docs.0x.org/_mcp/server"
            }
          }
        }
        ```
      </Step>

      <Step title="Test the connection">
        In Cursor’s chat, ask: **“Do you have access to an MCP server?”**

        Cursor should confirm access to CDP documentation search and any configured API endpoints.
