Connect AI to live energy prices

What is MCP and why does it matter?

The Model Context Protocol (MCP) lets AI assistants call external tools in real time. Instead of stale training data, your AI fetches live energy prices from Energy API — just by being asked a question.

Example: ask Claude "What's the latest German day-ahead power price?" and it calls the latest tool automatically.

Available MCP tools

Sixteen tools mapped to the real energy-api.com REST endpoints, grouped by category.

Getting started

Same URL for every client. Authenticate by putting your key in the URL as ?apikey=, or send it as an Authorization: Bearer or X-API-Key header if your client supports custom headers. There is no OAuth step — the key you already have from the dashboard works everywhere.

Connect to Claude

Works the same on claude.ai and in the Claude Desktop app — the connector is saved on your Claude account, not in a local file.

Connect with Claude Code

From any terminal (outside a claude session):

claude mcp add --transport http energy-api "https://mcp.energy-api.com/mcp" \
  --header "Authorization: Bearer YOUR_KEY"

No OAuth callback needed — the header carries your key directly. Verify with:

claude mcp list

Remove it with:

claude mcp remove energy-api

After setup, try: "What's the latest TTF gas and German power price?"

Connect to Cursor

You need an Energy API key from https://energy-api.com/api-keys.

Optional: a settings file instead

Paste into ~/.cursor/mcp.json (Mac) or %USERPROFILE%\.cursor\mcp.json (Windows), or .cursor/mcp.json in a project folder for a project-only setup. Save and restart Cursor.

      }
    }
  }
}

After setup, try: "Look up the OMIE Spain day-ahead electricity price"

Connect to ChatGPT

ChatGPT connectors call the URL you give them directly — put your key in the URL, never in chat.

Python: fetch a price example

A complete Python example that fetches the latest German day-ahead power price using the MCP protocol.
