datagouv

This MCP server provides access to the Data Gouv API via an MCP-compatible interface using an HTTP + SSE transport. The server exposes a dedicated tool called search-company, which lets you look up up-to-date information about French companies (name, address, directors, sector, etc.) by providing a search query such as a company name, a CEO name, or an address. Clients connect through the MCP server's SSE endpoint and issue a search-company operation to retrieve structured company data. If you’re testing locally, start the server and point your MCP client to the server's SSE URL (for example, http://localhost:3001/sse) and then invoke the search-company tool with your query.

Prerequisites:

• Node.js 22 (LTS) installed on your machine
• pnpm (version 10 or compatible)

Installation steps:

1. Clone or download the MCP server repository.
2. Install dependencies:

pnpm install

3. Start the server in development mode:

pnpm run dev

4. Configure your MCP client to connect to the server's SSE endpoint. For example:

{
  "mcpServers": {
    "data-gouv": {
      "url": "http://localhost:3001/sse"
    }
  }
}

5. Optional: run the MCP Inspector for debugging if needed:

pnpm run inspector

Access the inspector at http://localhost:5173.

Notes:

• This server is deprecated in favor of the official Datagouv MCP server. If you encounter issues, prefer the official repository at datagouv/datagouv-mcp-server.
• The server communicates using HTTP SSE as defined by the MCP specification, so ensure your client supports Server-Sent Events.
• Environment variables shown above (PORT and SSE_ENDPOINT) are examples; adjust as needed for your deployment environment.
• If you modify the server or run in a different environment, you may need to update the MCP client configuration to point to the correct SSE URL.
