Datagouv

You set up a dedicated MCP server to interact with Datagouv APIs, enabling you to query company data and other public records through a standardized MCP interface. This server uses HTTP+SSE transport to stream updates, making it straightforward to integrate Datagouv data into your MCP client workflows.

How to use

You can use this server in two ways. First, run it locally and connect your MCP client to the provided HTTP endpoint. Second, run it as a local stdio process and connect via a client that communicates through a local command.

How to install

Prerequisites you need on your host before installation are Node.js 22 (lts/jod) and pnpm 10. Install them if you haven’t already.

Install dependencies for the MCP server with the following command.

pnpm install

Start the MCP server in development mode with this command.

pnpm run dev

Configure your MCP client to use the server via HTTP by adding this configuration snippet.

{
  "mcpServers": {
    "data_gouv": {
      "url": "http://localhost:3001/sse"
    }
  }
}

Additional notes

Debugging the server is supported through an Inspector tool. Start the inspector with this command and open it in your browser to step through requests and responses.

pnpm run inspector

Access the inspector at http://localhost:5173
