Assistants

Assistants connect with the URL alone. Searching works signed out; when a tool needs your account (for example to use a subscription), the assistant opens a quarry sign-in.

Claude (claude.ai, Desktop)

1. Open Customize → Connectors, click +, then Add custom connector.
2. Name it quarry and paste https://quarry.market/api/mcp. Click Add.
3. In a chat, enable the connector and ask a question that needs sources.

On Team and Enterprise plans, an owner adds it first under Organization settings → Connectors → Add → Custom → Web.

Custom connectors on Claude don't accept custom headers, so API keys don't apply here: sign in with OAuth when asked.

ChatGPT

Requires a plan with Developer mode (Plus, Pro, Business, Enterprise or Edu, on the web).

1. Turn on Settings → Security and login → Developer mode.
2. Open Plugins, click + and create an app.
3. Enter the name quarry, a description, and the URL https://quarry.market/api/mcp. For authentication, choose Mixed (or OAuth) so you can connect your quarry account for subscriptions.

Meta Muse

Ask Muse to create a custom connector with the URL https://quarry.market/api/mcp. Muse saves it as a skill you can reuse in later chats.
