Everything you have learned so far lives in the OnZero web app. But the whole studio can also come to you - inside a chat in Claude, Codex, Cursor or any other MCP client - through the MCP connection. This is how OnZero stops being a website you visit and becomes a set of tools your assistant can use directly.

What the MCP unlocks

Once connected, 67 tools - character creation, image, video, voice, editing and workflows - become available directly inside whichever client you use. You get the full studio right in your conversation, without opening the web UI. The same account, the same characters, just driven by chat instead of clicks.

1. 1Open onzero → Settings → MCP. For Claude Code / Desktop, Codex, Cursor and any other client: generate an API key (oz_…). For claude.ai web: skip the key.
2. 2Claude Code: run `claude mcp add --transport http onzero https://onzero.ai/mcp --header "Authorization: Bearer oz_…"`. Desktop: mcp-remote in claude_desktop_config.json. claude.ai: Add custom connector → paste https://onzero.ai/mcp, leave Client ID/Secret empty, approve OAuth. Any other client: point it at https://onzero.ai/mcp over streamable HTTP with the same Bearer header.
3. 3Verify with a simple ask — e.g. “list my characters” (list_characters).

The connection is a one-time setup, and once it is in place the way you create changes completely. Instead of navigating menus, you just describe what you want. The next lesson is all about that: creating from a plain conversation.
