A side-by-side look at the Whalesync and Apiverket MCP MCP servers: transport, auth, tools, quality signals, and the config to install either one in Claude, Cursor, Windsurf or VS Code.
Verdict: choose Whalesync for data platforms work; choose Apiverket MCP for data platforms as a local process. You can also run both side by side in one mcpServers block.

govdata_discoverSearch and browse available Swedish government data endpoints in the Apiverket API.
Use this tool to find the right endpoint before calling govdata_query. The API covers 139 endpoints across 16 categories including weather, transport, economy, health, environment, parliament, police, education, and more.
Args:
- query (string, optional): Keyword to search across endpoint names, descriptions, and paths
- category (string, optional): Filter by category name
When called with no arguments, returns all available categories with endpoint counts.
Examples:
- Find weather endpoints: query="weather"
- Browse transport category: category="Transport"
- Find pension info: query="pension"
- List all categories: (no arguments)
Returns:
Matching endpoints with their paths, parameters, and descriptions.govdata_queryCall any Apiverket API endpoint to retrieve Swedish government data.
Use govdata_discover first to find the right endpoint path and required parameters. Then call this tool with the endpoint path and any path/query parameters.
Args:
- endpoint (string, required): The API path (e.g. "/v1/weather/{city}")
- path_params (object, optional): Values for path parameters like {city}, {code}, {id}
- query_params (object, optional): Query string parameters (q, limit, offset, lat, lon, etc.)
Examples:
- Current weather in Stockholm:
endpoint="/v1/weather/{city}", path_params={"city": "stockholm"}
- Search jobs:
endpoint="/v1/jobs/search", query_params={"q": "developer", "limit": 5}
- Train departures from Stockholm Central:
endpoint="/v1/transport/trains/{station}", path_params={"station": "Cst"}
- Exchange rates:
endpoint="/v1/rates"
- Population by municipality:
endpoint="/v1/population/{municipalityCode}", path_params={"municipalityCode": "0180"}
- Police events in Stockholm:
endpoint="/v1/police/events", query_params={"location": "Stockholm", "limit": 10}
- Find EV chargers near a location:
endpoint="/v1/infrastructure/ev-chargers", query_params={"lat": 59.33, "lon": 18.07}
Returns:
The API response as JSON, containing a "meta" envelope with request info and a "data" object with the actual data.
Error handling:
- Returns clear error messages if the API is unreachable, the endpoint doesn't exist, or parameters are invalid
- Large responses are automatically truncated with pagination guidancePaste either block (or both) into your client config, e.g. claude_desktop_config.json or ~/.cursor/mcp.json. We only show a config when the install command is confirmed.
