Install VitaminD Explorer

The server’s own address, for the clients that take one directly. Or connect Ahel once and every client you use reads it from one address, with the account kept on Ahel rather than in each client’s config.

Claude Code
claude mcp add --transport http --scope user vitamind-explorer 'https://getvitamind.app/api/mcp/mcp'
Run it once in your project, then open /mcp to approve any sign-in the server asks for.
Claude Desktop
https://getvitamind.app/api/mcp/mcp
Add a custom connector in Settings, paste this address, and approve the sign-in.
Cursor
cursor://anysphere.cursor-deeplink/mcp/install?name=vitamind-explorer&config=eyJ1cmwiOiJodHRwczovL2dldHZpdGFtaW5kLmFwcC9hcGkvbWNwL21jcCJ9
Open the link and Cursor adds the server at that address.
ChatGPT
https://getvitamind.app/api/mcp/mcp
In Settings, enable Developer mode, create an MCP app, and paste this address. Your plan and workspace must allow custom apps.
Codex
