Trafikverket MCP Server

A Model Context Protocol (MCP) server providing real-time access to Swedish road weather, traffic cameras, road conditions, and traffic flow data from Trafikverket (Swedish Transport Administration).

• Real-time weather data from 850+ Swedish road weather stations
• Traffic camera access with live images and geographic search
• Traffic situations including accidents, roadwork, and closures
• Traffic flow data with vehicle counts and average speeds
• Road surface conditions including ice, snow, and water depth
• Geographic proximity search for cameras and weather stations
• County-based filtering for regional queries

Get current weather data for a specific station by name.

Returns: Air/road temperatures, humidity, visibility, wind, precipitation, road conditions.

List available weather stations with optional filtering.

Find weather stations near geographic coordinates.

Get historical weather observations for trend analysis.

Get traffic cameras with optional filtering.

Returns: Camera locations, GPS coordinates, bearings, photo URLs.

Find cameras near geographic coordinates.

Fetch the actual image from a traffic camera.

Returns: Base64-encoded camera image.

Get current traffic incidents, accidents, roadwork, and closures.

Supports SQL-style wildcards: E% matches E4, E20, etc.

Get real-time traffic density and speed data.

Get road surface conditions including ice, snow, and water.

• Node.js 18+
• Trafikverket API key (free from api.trafikinfo.trafikverket.se)

Add to your MCP configuration (use absolute paths):

Production (compiled JavaScript):

{
  "mcpServers": {
    "trafikverket": {
      "command": "node",
      "args": ["/path/to/trafikverket-mcp/dist/index.js"],
      "env": {
        "TRAFIKVERKET_API_KEY": "YOUR_API_KEY"
      }
    }
  }
}

Development (TypeScript):

{
  "mcpServers": {
    "trafikverket": {
      "command": "npx",
      "args": ["tsx", "/path/to/trafikverket-mcp/src/index.ts"],
      "env": {
        "TRAFIKVERKET_API_KEY": "YOUR_API_KEY"
      }
    }
  }
}

Restart Claude after updating configuration.
