# Build with LLMs

The BILL API documentation Model Context Protocol (MCP) server enables AI-powered code editors like Cursor and Windsurf, plus general-purpose tools like Claude Desktop, to interact directly with the BILL API documentation.

The BILL API documentation MCP server is available at `https://developer.bill.com/mcp`.

The BILL API documentation LLMs.txt file is available at `https://developer.bill.com/llms.txt`.

## What is MCP?

Model Context Protocol (MCP) is an open standard that allows AI applications to securely access external data sources and tools. The BILL API documentation MCP server provides a set of features for AI agents.

| Feature                  | Description                                                                                               |
| :----------------------- | :-------------------------------------------------------------------------------------------------------- |
| **Context**              | Pull documentation in your AI agent's context                                                             |
| **Documentation search** | Enable your AI agent to search through the documentation website and to provide results and page content. |

## BILL API documentation MCP server setup

Configure your AI development tools to connect to the `https://developer.bill.com/mcp` server.

  <Tab title="Cursor">
    **`~/.cursor/mcp.json`configuration**

    ```json
    {
      "mcpServers": {
        "billcom": {
          "url": "https://developer.bill.com/mcp"
        }
      }
    }
    ```
  </Tab>

  <Tab title="Windsurf">

        }
      }
    }
    ```
  </Tab>

  <Tab title="Claude Desktop">
    **`claude_desktop_config.json`configuration**

    ```json
    {
      "mcpServers": {
        "billcom": {
          "url": "https://developer.bill.com/mcp"

## Test your API documentation MCP setup

Once configured, you can test your MCP server connection:

1. Open your AI editor, and start a new chat with the AI assistant.
2. Ask about BILL API documentation. Try a set of questions.
   * "How do I \[common use case]?"
   * "Show me an example of \[API functionality]"
   * "Create a \[integration type] using BILL API documentation"

The AI should now have access to your BILL API documentation account data and documentation through the MCP server.
