Connect your assistant

1. Install the GitHub App

Install the major-vault App on your personal account or an organisation, and choose the repositories Major Vault may reach. You can change that choice on GitHub at any time.

Install on GitHub

The App asks for little: read and write the contents of the chosen repositories, and read their metadata.

2. Wait until we switch it on

We review every new installation and switch it on by hand, usually within 24 hours. After installing, GitHub sends you to a status page. Keep it: once the installation is on, it shows your address and the buttons that add it.

3. Add the address to your assistant

The address has the name we gave your installation, for example https://vlt.majortom.ai/acme. Add it as a custom connector or MCP server:

  • claude.ai and Claude Desktop: Settings → Connectors → Add custom connector.
  • ChatGPT: Settings → Connectors, with developer mode on.
  • Claude Code: claude mcp add --transport http acme https://vlt.majortom.ai/acme
  • Other clients that speak MCP over HTTP, such as Codex or opencode: the same address, as a remote server.

Opened in a browser, the address shows the same steps for that name.

4. Sign in

The first time, you confirm on a page from this address which client is asking, then sign in on GitHub. The client keeps the sign-in and renews it by itself. The assistant can then read and write only where you yourself can.

Major Vault is made by majortom.ai. The tool pages are generated from the code of this build. For agents: llms.txt, llms-full.txt.
