# Quickstart: Connect Your AI Tool

You need a nativeMsg account (free to create, no credit card) and an AI tool that supports remote MCP servers. The connection is the same everywhere: add the server URL, sign in with your nativeMsg login, approve access.

**Server URL:** `https://mcp.nativemsg.com/mcp`

## Claude (claude.ai / desktop)

1. Settings → **Connectors** → **Add custom connector**
2. Name it **nativeMsg** and paste the server URL
3. Click Connect and sign in with your nativeMsg account
4. In a chat, enable nativeMsg from the tools menu and ask: *"Using nativeMsg, list my experiences."*

On Team/Enterprise plans an admin may need to allow custom connectors first.

## Claude Code

```bash
claude mcp add --transport http nativemsg https://mcp.nativemsg.com/mcp
```

Sign in when prompted. Verify with `/mcp` — nativeMsg should list its tools.

## ChatGPT

1. Settings → **Plugins** (on some builds: Connectors or Apps) → **Advanced settings** → turn on **Developer mode**
2. Choose **Create**: name it **nativeMsg**, paste the server URL, select **OAuth** as the authentication type
3. Sign in with your nativeMsg account when the OAuth window opens
4. In a new chat, open the **+** menu, enable Developer mode, and toggle **nativeMsg** on for that conversation

Requires a paid ChatGPT plan; on Business/Enterprise workspaces, an admin may need to enable connectors and Developer mode. Use the web app (chatgpt.com) to add the connector — the mobile and desktop apps pick it up afterward.

## Cursor

Add to your MCP configuration (Settings → MCP, or `.cursor/mcp.json`):

```json
{
  "mcpServers": {
    "nativemsg": { "url": "https://mcp.nativemsg.com/mcp" }
  }
}
```

Sign in via the browser window Cursor opens.

## Any other MCP client

Add `https://mcp.nativemsg.com/mcp` as a remote MCP server (Streamable HTTP transport) and complete the OAuth sign-in. The server advertises standard OAuth discovery metadata, so clients that implement the MCP authorization spec connect with no extra configuration.

## First things to try

* "List my experiences and tell me which channels each one runs on."
* "Add my phone as a tester device on our RCS channel and send me a test rich card."
* "Build a booking experience: when someone texts BOOK, show our three services, capture a preferred time, and confirm with an add-to-calendar button."

Your AI tool asks for confirmation before anything is sent to a real contact.

# Agent Instructions
This documentation is published with GitBook. GitBook is the documentation platform designed so that both humans and AI agents can read, navigate, and reason over technical content effectively. Learn more at gitbook.com.

## Querying This Documentation
If you need additional information that is not directly available in this page, you can query the documentation by asking a question.

Perform an HTTP GET request on the following URL with the `ask` and `goal` query parameters:

```
GET https://playbook.nativemsg.com/mcp/quickstart.md?ask=<question>&goal=<user_goal>
```

`ask` is the immediate question: it should be specific, self-contained, and written in natural language.
`goal` is what the user is ultimately trying to achieve, the reason they need the answer. Sharing it helps GitBook give you a better, more relevant answer. A goal is most helpful when it describes the outcome the user wants rather than restating the question. For example, with `ask=how do I create an API token`, a goal like `automate deployments from our CI pipeline` lets GitBook tailor the answer to that use case.

The response will contain a direct answer to the question and relevant excerpts and sources from the documentation.

Use this mechanism when the answer is not explicitly present in the current page, you need clarification or additional context, or you want to retrieve related documentation sections.
