# Building with AI

Integrate Sezzle without leaving your editor. Our MCP server lets an AI agent search these docs, and our skill teaches it how to build an integration. Every page is also available as markdown for any large language model (LLM).

## MCP Server

Sezzle has an <Tooltip tip="An MCP server implements the Model Context Protocol, a standard for connecting AI models to external tools and data.">MCP server</Tooltip> that lets you search this documentation in natural language from your IDE, terminal, or any MCP-compatible tool. It reads Sezzle's documentation only; it never calls the Sezzle API.

### Setup

<Steps>
  <Step title="Install the MCP server">
    Run the following command. It detects the AI tools configured in the current project (Cursor, Claude Code, VS Code, and others) and asks which ones to install to. Add `-g` to install globally instead of into the current project.

    ```bash theme={"system"}
    npx add-mcp https://docs.sezzle.com/mcp --name sezzle-docs
    ```

    To configure a client by hand instead:

    <Tabs>
      <Tab title="Claude Code">
        Add the server:

        ```bash theme={"system"}
        claude mcp add --transport http sezzle-docs https://docs.sezzle.com/mcp
        ```

        Then confirm it connected:

        ```bash theme={"system"}
        claude mcp list
        ```
      </Tab>

      <Tab title="Cursor">
        Press <kbd>Command</kbd> + <kbd>Shift</kbd> + <kbd>P</kbd> (<kbd>Ctrl</kbd> + <kbd>Shift</kbd> + <kbd>P</kbd> on Windows), search for `Open MCP settings`, and click **Add custom MCP** to open `mcp.json`. Add:

        ```json theme={"system"}
        {
          "mcpServers": {
            "sezzle-docs": {
              "url": "https://docs.sezzle.com/mcp"
            }
          }
        }
        ```
      </Tab>

      <Tab title="VS Code">
        Create a `.vscode/mcp.json` file containing:

        ```json theme={"system"}
        {
          "servers": {
            "sezzle-docs": {
              "type": "http",
              "url": "https://docs.sezzle.com/mcp"
            }
          }
        }
        ```
      </Tab>
    </Tabs>
  </Step>

  <Step title="Begin prompting">
    Ask a question, and your agent searches Sezzle's documentation for the answer.

    **Example prompts:**

    * "How do I create a Sezzle checkout session, and what do I do next?"
    * "How do I capture an authorized order?"
    * "What's the difference between Authorize Only and Authorize and Capture?"
    * "How do I integrate the Sezzle iOS SDK?"
    * "Which webhook events does Sezzle send, and how do I subscribe to them?"
    * "How do I add the Sezzle widget to a WooCommerce store?"
  </Step>
</Steps>

## Skills

A skill tells your AI agent how to build a Sezzle integration: which API calls to make and in what order, how to authenticate, which webhooks to handle, and how to test in our sandbox.

<Tip>
  The MCP server lets your agent *search* our docs. The skill tells it *how to build*.
