Data Loireatlantique

What Data Loireatlantique does

Data Loireatlantique exposes Loire-Atlantique Open Data through MCP. The source is the OpenDataSoft-based portal at data.loire-atlantique.fr, with datasets covering areas such as departmental services, roads, education, and the environment.

The integration is intended for agents that need to discover relevant datasets and work with their structured records. It is an independent, unofficial connection and is not affiliated with, endorsed by, or published by the upstream data provider.

How it works

The hosted connection is available at https://gateway.pipeworx.io/data-loireatlantique/mcp. An MCP client can connect to that URL directly. The same gateway also exposes a full endpoint at https://gateway.pipeworx.io/mcp, where all Pipeworx packs are available through the gateway’s broader tool set.

A scoped hosted connection lists the Loire-Atlantique tools alongside shared Pipeworx meta-tools. Those shared tools can route questions to other catalog sources through ask_pipeworx. The pack endpoint and the full gateway reach the same underlying collection of live data sources; they differ in which pack tools are listed directly.

The service can also be called without an MCP client through the gateway’s HTTP tool API. An npm package provides a local stdio bridge that forwards requests to the hosted endpoint, so the local process still needs network access and has no offline mode.

Setup and configuration

For a hosted MCP connection, add the following server URL to an MCP client:

{
  "mcpServers": {
    "data-loireatlantique": {
      "url": "https://gateway.pipeworx.io/data-loireatlantique/mcp"
    }
  }
}

The npm option starts the bridge with npx:

{
  "mcpServers": {
    "data-loireatlantique": {
      "command": "npx",
      "args": ["-y", "@pipeworx/mcp-data-loireatlantique"]
    }
  }
}

Anonymous use is available with a limit of 50 calls per day. A free Pipeworx account raises the limit to 200 calls per day. Add PIPEWORX_API_KEY to the npm server environment to authenticate with a key. Set PIPEWORX_META_TOOLS=1 if the local bridge should also list the shared gateway tools. The package is distributed under the MIT license.

Tools and capabilities

• search_datasets finds Loire-Atlantique datasets by keyword and returns IDs, titles, themes, and record counts.
• dataset_info returns a dataset’s metadata, including its fields, schema, themes, and record count. Use it first to identify valid column names.
• query retrieves or summarizes records with ODSQL. It supports where filters, group_by and select aggregation, order_by sorting, and limit/offset pagination.
• ask_pipeworx and other shared gateway tools may appear on hosted or optionally configured connections, enabling broader Pipeworx routing beyond this data pack.

Limitations and notes

Requests require network access. Anonymous and authenticated usage have different daily call limits, and authenticated calls are metered through Pipeworx. The hosted endpoint lists additional shared tools alongside the pack tools, while the npm bridge lists only the pack tools unless meta-tools are enabled. When using an HTTPS proxy with the npm bridge, Node’s proxy support may require NODE_USE_ENV_PROXY=1 on supported Node versions.
