Add Opennan to your AI app

One install gives your AI every Opennan tool: video, images, chat, voice, music, sound effects, 3D, captions and dubbing. Pick your app and follow the steps.

MCP serverhttps://api.opennan.com/v1/mcp

Works in the Codex CLI, the Codex app and the Codex IDE extension: they share ~/.codex/config.toml. If the app or IDE does not see OPENNAN_KEY, use the config.toml option with your key in it. Codex asks before each tool call: approve it to go on.

  1. Get an API key

    Create a key in the console. It starts with sk- and uses the same balance as the website.

    Create a key

  2. Save your key as OPENNAN_KEY

    # macOS / Linux (zsh shown; bash: ~/.bashrc)
echo 'export OPENNAN_KEY="sk-..."' >> ~/.zshrc
source ~/.zshrc

# Windows (PowerShell), then open a new terminal
setx OPENNAN_KEY "sk-..."

  3. Install the Opennan plugin: the server plus a skill that teaches your AI to pick models, confirm prices and wait for results

    codex plugin marketplace add Opennan/opennan-ai-plugin
codex plugin add opennan@opennan

  4. Or add only the server

    codex mcp add opennan --url https://api.opennan.com/v1/mcp --bearer-token-env-var OPENNAN_KEY

  5. Or add this to ~/.codex/config.toml

    [mcp_servers.opennan]
url = "https://api.opennan.com/v1/mcp"
http_headers = { Authorization = "Bearer sk-..." }

  6. Check that opennan is listed

    codex mcp list

  7. Restart Codex, then ask for anything

    “Make a 5 second video of rain on a neon street, a song to go with it and a poster image.”

Replace sk-... with your own key and keep it private: anyone who has it can spend your balance. Your app can list the tools before you add a key; making anything needs one.
