A Model Context Protocol (MCP) server that enables AI assistants to create Datawrapper charts. Built on the datawrapper Python library with Pydantic validation.

Example Usage

Here's a complete example showing how to create, publish, update, and display a chart by chatting with the assistant:

"Create a datawrapper line chart showing temperature trends with this data:
2020, 15.5
2021, 16.0
2022, 16.5
2023, 17.0"
# The assistant creates the chart and returns the chart ID, e.g., "abc123"

"Publish it."
# The assistant publishes it and returns the public URL

"Update chart with new data for 2024: 17.2°C"
# The assistant updates the chart with the new data point

"Make the line color dodger blue."
# The assistant updates the chart configuration to set the line color

"Show me the editor URL."
# The assistant returns the Datawrapper editor URL where you can view/edit the chart

"Show me the PNG."
# The assistant embeds the PNG image of the chart in its contained response.

"Suggest five ways to improve the chart."
# See what happens!

Getting Started

Requirements

A Datawrapper account (sign up at https://datawrapper.de/signup/)
An MCP client such as Claude or OpenAI Codex
Python 3.10 or higher
A Python package installer such as pip or uvx

Get Your API Token

Go to https://app.datawrapper.de/account/api-tokens
Create a new API token
Add it to your MCP configuration as shown below

Installation

Claude Code

Using uvx (recommended)

Configure your MCP client in claude_desktop_config.json:

{
  "mcpServers": {
    "datawrapper": {
      "command": "uvx",
      "args": ["datawrapper-mcp"],
      "env": {
        "DATAWRAPPER_ACCESS_TOKEN": "your-token-here"
      }
    }
  }
}

Using pip

First install the package:

pip install datawrapper-mcp

Then configure your MCP client in claude_desktop_config.json:

{
  "mcpServers": {
    "datawrapper": {
      "command": "datawrapper-mcp",
      "env": {
        "DATAWRAPPER_ACCESS_TOKEN": "your-token-here"
      }
    }
  }
}

OpenAI Codex

CLI with uvx

Add this to ~/.codex/config.toml:

[mcp_servers.datawrapper]
args = ["datawrapper-mcp"]
command = "uvx"
startup_timeout_sec = 30

[mcp_servers.datawrapper.env]
DATAWRAPPER_ACCESS_TOKEN = "your-token-here"

CLI with pip

First install the package:

pip install datawrapper-mcp

Then add this to ~/.codex/config.toml:

[mcp_servers.datawrapper]
command = "datawrapper-mcp"
startup_timeout_sec = 30

[mcp_servers.datawrapper.env]
DATAWRAPPER_ACCESS_TOKEN = "your-token-here"

Secure secrets

For enhanced security, you can configure a pass-through environment variable by ensuring that DATAWRAPPER_ACCESS_TOKEN is set in your environment, and replacing this in your config.toml:

[mcp_servers.datawrapper.env]
DATAWRAPPER_ACCESS_TOKEN = "your-token-here"

With this:

env_vars = ["DATAWRAPPER_ACCESS_TOKEN"]

This ensures that the value set for DATAWRAPPER_ACCESS_TOKEN in your environment is passed through to Codex without having to store the secret as text in a config file.

Desktop application

If you're using the Codex Desktop Application, you can set up the MCP in your settings under MCP servers:

Under Custom servers, click Add server
Under Name, enter datawrapper-mcp
Select STDIO
Under Command to launch, type uvx (you must have uv installed)
Under Arguments, add datawrapper-mcp
Under Environment variables, add DATAWRAPPER_ACCESS_TOKEN as the key and your token as the value
Click Save

Kubernetes Deployment

For enterprise deployments, this server can be deployed to Kubernetes using HTTP transport:

Building the Docker Image

docker build -t datawrapper-mcp:latest .

Running with Docker

docker run -p 8501:8501 \
  -e DATAWRAPPER_ACCESS_TOKEN=your-token-here \
  -e MCP_SERVER_HOST=0.0.0.0 \
  -e MCP_SERVER_PORT=8501 \
  datawrapper-mcp:latest

Environment Variables

DATAWRAPPER_ACCESS_TOKEN: Your Datawrapper API token (required)
MCP_SERVER_HOST: Server host (default: 0.0.0.0)
MCP_SERVER_PORT: Server port (default: 8501)
MCP_SERVER_NAME: Server name (default: datawrapper-mcp)

Health Check Endpoint

The HTTP server includes a /healthz endpoint for Kubernetes liveness and readiness probes:

curl http://localhost:8501/healthz
# Returns: {"status": "healthy", "service": "datawrapper-mcp"}
