Data Bs

MCP server for any Huwise/Opendatasoft data portal.

Installation

uv sync

Usage

uv run main.py

Debug

npx @modelcontextprotocol/inspector uv run main.py

Install with uvx

uvx --from git+https://github.com/DCC-BS/mcp-data-bs data-bs-mcp

Selecting a catalog

The catalog is chosen by whoever deploys the server via the .env file next to main.py. All Huwise/Opendatasoft portals share the same API path, so you only set the domain:

# .env
DATA_PORTAL_DOMAIN=data.bl.ch

The full API base URL is built as https://<domain>/api/explore/v2.1.

The .env file is committed, so a fork carries its catalog choice through uvx installs as well.

{
  "mcpServers": {

      ]
    }

Tools

get_datasets

Search and list available datasets.

Two search modes:

• semantic (default): ranks the catalog by meaning using the vector_similarity explore endpoint from Huwise. Best for natural-language / conceptual queries. Matches synonyms and other languages.
• lexical: classic full-text match on the exact terms.

# semantic (default) — natural language, ranked by relevance
get_datasets(search="air quality measurements")

# lexical — exact full-text match
get_datasets(search="luft", search_mode="lexical")

# combine with facet filters
get_datasets(search="bevölkerung", refine="publisher:Statistisches Amt")
