MCP Server (AI)

Use the NinePay documentation with AI assistants

The NinePay MCP Server lets AI assistants such as Claude, ChatGPT, Cursor and VS Code query this documentation directly, always up to date: endpoints, parameters, examples and guides.

With it, your assistant answers integration questions and writes code based on the official documentation, without you copying and pasting pages.

Documentation only

The MCP Server is public and read-only. It doesn't access your account, doesn't use your API key and doesn't call the NinePay API.

Connect your assistant to the MCP Server

The MCP Server address is:

URL

https://docs.ninepay.com.br/mcp

What the assistant can query

Tool	What it does
`list-specs`	Lists the available OpenAPI specs
`list-endpoints`	Lists every API endpoint
`search-endpoints`	Searches endpoints by path, name, parameter or field
`get-endpoint`	Returns an endpoint's details: parameters, body, responses and examples
`search`	Searches the guides and the reference
`fetch`	Reads a documentation page as Markdown

Configure the MCP Server

On any documentation page, the menu next to Copiar página has shortcuts to install in Cursor and VS Code and to copy the configuration.

Cursor

Add to ~/.cursor/mcp.json:

mcp.json

{
  "mcpServers": {
    "ninepay-docs-mcp": {
      "url": "https://docs.ninepay.com.br/mcp"
    }
  }
}

VS Code

Add to the project's .vscode/mcp.json:

.vscode/mcp.json

{
  "servers": {
    "ninepay-docs-mcp": {
      "type": "http",
      "url": "https://docs.ninepay.com.br/mcp"
    }
  }
}

Claude Code

Terminal

claude mcp add --transport http ninepay-docs-mcp https://docs.ninepay.com.br/mcp

Claude Desktop, ChatGPT and others

Add a remote MCP connector with the URL https://docs.ninepay.com.br/mcp. The menu path depends on the app: check its documentation.

Test the configuration

Once connected, ask your assistant something like:

"How do I create a recurring subscription on NinePay?"
"Which fields are required to create a payment?"
"Show a Node.js example to charge with PIX in the sandbox."

If the answer cites NinePay endpoints and guides, the MCP Server is working.

Use the LLMs.txt file

For assistants that don't use MCP, the documentation is also available as text files made for AI:

/llms.txt: an index of every page.
/llms-full.txt: the whole documentation in a single file.

Every page also has a Markdown version: replace the end of its address with .md.
