API keys
Drive this account from Claude, ChatGPT, Cursor, Claude Code, a script or the CLI. Hosts connect over OAuth; a key is shown once, when you create it.
Connected apps
Hosts you signed in from - Claude, ChatGPT, Cursor, Claude Code - through the hosted MCP server. Disconnecting ends the host's access at once.
Send the key as Authorization: Bearer <key>. Each key carries only the scopes you give it, and 600 requests an hour.
