# Developer tools

> The documentation in your AI assistant (MCP), as Markdown and llms.txt, and the Postman collection with every request ready to use.

Shortcuts to integrate faster: the documentation inside your AI assistant and the requests ready to test.

## MCP

The MCP server lets your AI assistant (Claude, Cursor, VS Code, ChatGPT and others) **search and read this documentation** while you code. Instead of answering from memory, it looks up the right page and uses the real field names, accepted values and error codes.

```
https://doc.rapidchargeback.com/mcp/
```

It only reads the public documentation: it asks for no credentials, does not access your Rapid account and does not call the API. The documentation is available in Portuguese, English and Spanish; ask the assistant to use English (the tools take a `language` parameter).

### Claude Code

```bash
claude mcp add --transport http rapid-docs https://doc.rapidchargeback.com/mcp/
```

### Cursor

In `~/.cursor/mcp.json` (or `.cursor/mcp.json` in the project):

```json
{
  "mcpServers": {
    "rapid-docs": { "url": "https://doc.rapidchargeback.com/mcp/" }
  }
}
```

### VS Code

In `.vscode/mcp.json` in the project:

```json
{
  "servers": {
    "rapid-docs": { "type": "http", "url": "https://doc.rapidchargeback.com/mcp/" }
  }
}
```

### Claude (app and web)

Under **Settings > Connectors > Add custom connector**, enter the name `Rapid` and the URL above.

### Other clients

Any MCP client with HTTP transport works with the same URL.

### What the assistant can do

| Tool | What it does |
|---|---|
| `search_docs` | Searches by topic, field name, error code, header or endpoint path. Corrects typos |
| `get_page` | Reads a whole page in Markdown |
| `list_pages` | Lists every page, in reading order |

Example request: *"Using the Rapid documentation, write the alert webhook handler in Node.js, validating the signature."*

## Copy a page

Every page has the **Copy page** button, next to the title. It copies the page as Markdown, the format you can paste into an AI assistant without losing tables or code blocks. The menu next to the button opens the same page directly in ChatGPT or Claude.

Each page is also available as Markdown at its own address, replacing the trailing slash with `.md`:

```
https://doc.rapidchargeback.com/en/canais/webhook/payload.md
```

## llms.txt

For tools that read the documentation all at once:

| File | Content |
|---|---|
| [`/en/llms.txt`](https://doc.rapidchargeback.com/en/llms.txt) | Index of every page, with a description and a link to the Markdown |
| [`/en/llms-full.txt`](https://doc.rapidchargeback.com/en/llms-full.txt) | The whole documentation in a single file |

## Postman collection

Every example request in this documentation, organized by the menu sections.

1. Download the [collection](https://doc.rapidchargeback.com/en/rapid.postman_collection.json).
2. In Postman, click **Import** and choose the file.
3. In the collection variables, fill in `client_id` and `client_secret` with the credentials from the dashboard (see [Authentication](https://doc.rapidchargeback.com/en/referencia/autenticacao/)). Basic authentication is already set up in the collection.

The IDs in the examples are fictitious (see [Canonical examples](https://doc.rapidchargeback.com/en/referencia/exemplos-canonicos/)): replace them with your account's before sending. The collection is generated from the examples on the pages, so it follows the documentation.
