Opennan

OpenNan AI pluginEvery AI tool inside Claude Code and Codex

Add one plugin, then ask your AI for a video, a song, a voice-over or a 3D model. It picks the model, shows the price and brings back the result.

Free · Claude Code and Codex · Other AI apps through MCP

Two commands in your terminal. Set OPENNAN_KEY to your API key first.

What your AI can make

One plugin, every OpenNan tool. Ask in plain words.

  • VideosFrom a prompt or a start image.
  • ImagesMake new pictures or edit your own.
  • VoiceSpeech in stock voices or your own cloned voice.
  • Music and sound effectsSongs, instrumentals and sound effects for any scene.
  • 3DProps and rigged characters, ready for games.
  • Captions and transcriptsSubtitles for any video, translated if you want.
  • Other AI modelsAsk another text model for a second opinion.
  • And moreNew OpenNan tools appear in your AI on their own.

It teaches your AI to work well

The plugin comes with a skill, so your AI uses OpenNan the way a careful person would.

  • Picks the right modelThe cheapest one that can do the job, unless you ask for top quality.
  • Shows the price firstTells you what a run costs and waits for your yes before it pays.
  • Never pays twiceIf a call times out, it retries the same run instead of starting a new one.
  • Waits for resultsLong jobs like video finish in the background; your AI checks back and tells you.
  • Brings back the filesEvery link to your video, image, audio or model, plus what it cost.
  • Keeps your key privateIt never asks you to paste your key into the chat.

Install in a few minutes

Pick your AI app. Claude Code and Codex get the plugin; every other app adds the same server.

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.

Free plugin, pay per run

No plan and no subscription.

  • PluginFreeInstalling it and listing the tools costs nothing.
  • Each runPrice shown firstPaid from your OpenNan balance, at the price your AI showed you.
  • Failed runsRefundedIf a run fails, the money goes back to your balance automatically.

Questions

Is the plugin free?

Yes. You pay only for the tools you run, from your OpenNan balance, and your AI shows the price before each paid run.

Which apps does it work in?

The plugin installs in Claude Code and in Codex.

I use Cursor, VS Code or another app.

Add the OpenNan MCP server instead. The install guide on this page has the steps for Cursor, VS Code, Windsurf, Gemini CLI, Claude Desktop, OpenCode and any other app that supports MCP.

Is my API key safe?

Your key stays in your own computer's settings, in the OPENNAN_KEY variable. The plugin never asks you to paste it into the chat. Anyone who has your key can spend your balance, so keep it private.

Can I try it without a key?

Yes. Your AI can list every tool and model with its price without a key. Making anything needs a key from the console.

Can I read the plugin's code?

Yes. It is public on GitHub under the MIT license.
