AI connections

Connect Claude apps

claude.ai, Claude Desktop and the Claude mobile apps, through a custom connector. These steps connect it to the Main Team MCP server at https://mcp.main-team.org/mcp.

Connect

  1. In Claude, open Customize, then Connectors. Select + and then Add custom connector.

  2. Name it Main Team, paste the server URL and add it:

    Server URL
    https://mcp.main-team.org/mcp
  3. If Claude asks how it should identify itself, choose Use Claude’s published identity. Then select Connect: Main Team’s sign-in page opens.

  • On a Team or Enterprise plan, an owner adds the connector once, under Organization settings, Connectors. Members then open Customize, Connectors and select Connect.
  • A connector you add on claude.ai is also there in Claude Desktop and the mobile apps. The Free plan allows one custom connector.

Main Team’s sign-in page opens at auth.main-team.org. Sign in the way you always do, tick the olympiads the connection should cover, and decide whether the app may change anything — reading only is the default. How a connection works.

Add the skills

The Main Team skills teach your agent how the server works: to say whose account it is on, to read before it changes anything, to preview and confirm, and never to help with an exam in progress. Agent skills lists them and how to add them to Claude apps.

Verify

Ask your agent:

Which Main Team account am I connected to, and may you change anything?

It answers with your own name and role, the olympiads the connection covers and whether it may change anything. If any of that is not what you expected, disconnect and connect again.

Troubleshooting

Claude cannot reach the server
Claude connects from Anthropic’s cloud, not from your computer, so a connector works the same on every device. Check the URL has no spaces and ends in /mcp.
Sign-in says this app is not allowed
A student account may connect only the verified apps: Claude apps, Claude Code, ChatGPT, Codex and VS Code. Teachers and partners may connect the others too.
The app asks you to sign in again
A connection ends after a time without use, at the end of its lifetime, when you disconnect it and whenever your password changes. Sign in again from the app.
A tool is refused and names your panel
Something that cannot be undone needs your app to ask you directly. When it cannot, the answer carries a link into your panel; do it there.
