Dev.to MCP Server

A remote Model Context Protocol (MCP) server for interacting with the dev.to public API without requiring authentication.

Features

This MCP server provides access to the following dev.to public API endpoints:

• get_articles - Get articles from dev.to with optional filters (username, tag, state, pagination)
• get_article - Get a specific article by ID or path
• get_user - Get user information by ID or username
• get_tags - Get popular tags from dev.to
• get_comments - Get comments for a specific article
• search_articles - Search articles using query parameters

Installation

Using npm

Usage

The server runs as a remote HTTP server on port 3000 (or the PORT environment variable) and can be used with any MCP-compatible client.

npm start

The server will be available at http://localhost:3000 for MCP connections.

Docker

Using Pre-built Image

Pull and run the pre-built Docker image:

# Pull the image
docker pull docker.io/nickytonline/dev-to-mcp:latest

# Run it
docker run -d \
  --name dev-to-mcp \
  -e NODE_ENV=production \
  -e PORT=3000 \
  -p 3000:3000 \
  --restart unless-stopped \
  docker.io/nickytonline/dev-to-mcp:latest

Once it's up, check health status via:

curl -fsS http://127.0.0.1:3000/mcp

The server will be available at http://localhost:3000/mcp for MCP connections.

Building from Source

Build and run the MCP server using Docker:

# Build the Docker image
docker build -t dev-to-mcp .

# Run the container
docker run -p 3000:3000 dev-to-mcp

Docker Compose

Using the pre-built image with Docker Compose:

services:
  dev-to-mcp:
    image: docker.io/nickytonline/dev-to-mcp:latest
    container_name: dev-to-mcp
    restart: unless-stopped
    environment:
      NODE_ENV: production
      PORT: 3000
    networks:
      - main
    healthcheck:
      # Uses $PORT at runtime; defaults to 3000 if not set
      test:
        [
          "CMD-SHELL",
          "curl -fsS http://127.0.0.1:${PORT:-3000}/mcp >/dev/null || exit 1",
        ]
      interval: 15s
      timeout: 5s
      retries: 5
      start_period: 30s

networks:
  main: {}

For development with a local build, you can also use Docker Compose:

# docker-compose.yml
version: "3.8"
services:
  dev-to-mcp:
    build: .
    ports:
      - "3000:3000"
    environment:
      - PORT=3000

docker-compose up --build
