Connect your AI

Add our connector to your AI app once, for your whole account. Then ask it to change your servers in plain words. You choose what it may do on its own, and you can undo anything it did.

Connector address

https://mcp.test.quarrymc.net/mcp

Paste this into your AI app. You also find it in the panel under AI.

Connect Claude

You add the connector once, on the Claude website. After that it works in the Claude desktop app and the Claude phone apps too, because they use the same account. Free Claude accounts can add one custom connector, and you only ever need one for all your servers.

Menu names in Claude change from time to time. If a step looks different, look for Connectors in Claude's settings.

On the web or the desktop app

Open Claude and go to Settings, then Connectors.
Choose Add custom connector.
For the name, type Server Host (dev). For the address, paste this:
```
https://mcp.test.quarrymc.net/mcp
```
Choose Add, then Connect. Claude sends you to Server Host to sign in.
Sign in, then check the consent screen: which servers Claude may reach, and what it may do on each one (Allow, Ask or Block). Change anything you like, then choose Approve.
Back in Claude, start a new chat and make sure the connector is switched on for it (in the chat's tools menu).

Now ask something like "list my servers" to check it works.

On a Team or Enterprise plan, an owner of your Claude organization may need to add the connector for the organization first. Then you connect it for yourself in Settings, Connectors.

On your phone

Add the connector on the web first, as above. Then open the Claude app on your phone, start a new chat and switch the connector on in the chat's tools menu. You do not need to add it again.

Good to know

Your AI never gets your password. It gets a key that only works through our connector, and you can cut it off at any time in Account, Connected AIs.
While our own name is still a placeholder, the connector is called Server Host (dev) inside Claude. It changes later; nothing for you to do.
What happens next, and how Allow, Ask and Block work: see Connecting your AI.

Connect ChatGPT

ChatGPT can use the connector on the plans that allow custom connectors, which today means a paid plan with developer mode. The free ChatGPT plan cannot add custom connectors. You add it on the ChatGPT website.

Menu names in ChatGPT change from time to time. If a step looks different, look for Apps, Connectors or Developer mode in ChatGPT's settings.

Add the connector

Open ChatGPT on the web and go to Settings, then Apps and connectors (or Connectors).
Open Advanced settings and turn on Developer mode. ChatGPT shows a warning about custom connectors; read it, then turn it on.
Choose Create (or Add connector).
For the name, type Server Host (dev). For the server address (MCP server URL), paste this:
```
https://mcp.test.quarrymc.net/mcp
```
For authentication, pick OAuth. Tick that you trust this connector, then choose Create.
ChatGPT sends you to Server Host to sign in. Sign in, check the consent screen (which servers it may reach, and Allow, Ask or Block for each action), then choose Approve.

Use it in a chat

Start a new chat, open the tools menu (the + button), choose Developer mode or More, and pick the Server Host (dev) connector. Then ask something like "list my servers".

Good to know

ChatGPT asks you to confirm actions that change things. That is ChatGPT's own check; our Allow, Ask and Block settings still apply on top of it.
You can cut the connection at any time in Account, Connected AIs on Server Host, or by removing the connector in ChatGPT.
How permissions, approvals and undo work: see Connecting your AI.

Connect Claude Code, Cursor and other MCP apps

Any app that supports remote MCP servers can use the connector. It speaks the MCP standard over HTTP and signs in with OAuth, so you never paste a password or a key: the app opens a Server Host sign-in page the first time.

The connector address is:

https://mcp.test.quarrymc.net/mcp

Claude Code

Run this in a terminal:

claude mcp add --transport http server-host-dev https://mcp.test.quarrymc.net/mcp

Then start Claude Code, type /mcp, pick the server-host-dev server and choose to sign in. Your browser opens the Server Host sign-in and consent screen.

Cursor

Open Cursor's settings, find MCP (or Tools and integrations) and add a new MCP server. Or put this in the mcp.json file Cursor uses for MCP servers:

{
  "mcpServers": {
    "server-host-dev": {
      "url": "https://mcp.test.quarrymc.net/mcp"
    }
  }
}

Cursor then asks you to sign in to Server Host in your browser.

VS Code

Add this to the .vscode/mcp.json file in your project, or run the MCP: Add Server command and choose HTTP:

{
  "servers": {
    "server-host-dev": {
      "type": "http",
      "url": "https://mcp.test.quarrymc.net/mcp"
    }
  }
}

Any other app

Look for "add MCP server", "remote MCP" or "custom connector" in the app's settings, and give it the address above. The app must support:

remote MCP over streamable HTTP, and
OAuth sign-in with dynamic client registration.

Apps that only run local MCP servers (started as a program on your computer) cannot use it yet. Gemini and other apps will be listed here when they support remote MCP servers.

Good to know

The first time, you see the consent screen: which servers this app may reach, and Allow, Ask or Block for each action. See Connecting your AI.
Every app you connect shows up in Account, Connected AIs, where you can cut it off at once.
