Carbon Intensity MCP Server

An MCP (Model Context Protocol) server that provides access to the UK Carbon Intensity API from National Energy System Operator (NESO).

Features

• Get current carbon intensity data for Great Britain
• Retrieve historical and forecast carbon intensity data
• Access regional carbon intensity data by postcode or region ID
• Get generation mix data (renewable vs non-renewable sources)
• Statistical analysis of carbon intensity trends
• Carbon intensity factors for different fuel types

Installation

From PyPI (Recommended)

# No installation needed - uvx will handle it automatically
uvx carbon-intensity-mcp --help

From Source

git clone https://github.com/benomahony/carbon-intensity-mcp.git
cd carbon-intensity-mcp
uv sync

Usage

If using from PyPI

Add to your MCP client configuration:

{
  "mcpServers": {
    "carbon-intensity": {
      "command": "uvx",
      "args": ["carbon-intensity-mcp"]
    }
  }
}

If installed from source

Add to your MCP client configuration:

{
  "mcpServers": {
    "carbon-intensity": {
      "command": "uv",
      "args": ["--directory", "/path/to/carbon-intensity-mcp", "run", "carbon-intensity-mcp"]
    }
  }
}

Important: Replace /path/to/carbon-intensity-mcp with the actual absolute path to your cloned repository.

For the example configuration provided:

cp example-config.json ~/.config/claude/mcp_servers.json
# Edit the path in the file to match your setup

Testing

Test the server works:

# If using from PyPI
echo '{"jsonrpc": "2.0", "id": 1, "method": "initialize", "params": {"protocolVersion": "2024-11-05", "capabilities": {"tools": {}}, "clientInfo": {"name": "test", "version": "1.0.0"}}}' | uvx carbon-intensity-mcp

# If installed from source
echo '{"jsonrpc": "2.0", "id": 1, "method": "initialize", "params": {"protocolVersion": "2024-11-05", "capabilities": {"tools": {}}, "clientInfo": {"name": "test", "version": "1.0.0"}}}' | uv run carbon-intensity-mcp
