CBS Open Data MCP Server

Provides access to CBS Open Data catalogs, datasets, dimensions, and observations via an MCP server.

Installation

Add the following to your MCP client configuration file.

Configuration

{
  "mcpServers": {
    "dstotijn-mcp-cbs-cijfers-open-data": {
      "command": "go",
      "args": [
        "run",
        "github.com/dstotijn/mcp-cbs-cijfers-open-data@latest"
      ]
    }
  }
}

You can use this MCP server to interact with the CBS Open Data API through AI-enabled tools. It exposes a set of operations that let you list catalogs and datasets, inspect metadata and dimensions, and retrieve observations with flexible filtering. This makes it easy to build AI assistants or automation that explore and analyze CBS Open Data.

How to use

You will connect an MCP client to the server to perform actions like listing catalogs, querying datasets, and fetching observations. Use the client’s standard MCP call patterns to invoke the available tools. Start by discovering what catalogs exist, then drill into datasets, their dimensions, and observations. You can shape responses with filters, sorting, and pagination so you only get the data you need.

How to install

Prerequisites: you need Go installed on your system to run the MCP server locally. Ensure your Go toolchain is available on your PATH.

{
  "mcpServers": {
    "cbs_cijfers_open": {
      "command": "go",
      "args": ["run", "github.com/dstotijn/mcp-cbs-cijfers-open-data@latest"]
    }
  }
}

Additional sections

Configuration notes: the MCP server exposes a standard set of tools that you can call through a MCP client. The available tools let you retrieve catalogs, query datasets with advanced filters, inspect dataset dimensions and their values, and fetch observations with optional filters and pagination.
