Install Bar-JEPA — Bar Chart Value Extraction in Amp

What you need first

• Amp, installed.
• Nothing else: the server runs on its publisher's machines and Amp connects to it.

Steps

1. Open ~/.codex/config.toml, or create it. The Codex CLI, its IDE extension and the ChatGPT desktop app share this file.
2. Add this table at the end of the file.

{
  "amp.mcpServers": {
    "bar-jepa-chart-extraction": {
      "url": "https://hugging-apps-bar-jepa-chart-extraction.hf.space/gradio_api/mcp/sse"
    }
  }
}

3. Save the file and restart Amp.

Check it worked

Ask Amp: List the tools of bar-jepa-chart-extraction. It should list 1 tool.

If it does not start

401 Unauthorized

The endpoint wants a sign-in or a key. Sign in when Amp asks.

Nothing changes after a restart

The file is not valid JSON any more. Look for a missing comma where the block was added.
