Dev Blog MCP Server

A Model Context Protocol (MCP) server that enables AI assistants to publish blog posts directly to Dev.to. This server provides a seamless way to integrate blog publishing capabilities into your AI workflows.

Features

• 🚀 Direct Dev.to Publishing: Publish blog posts directly to Dev.to via MCP
• 📝 Rich Content Support: Full Markdown support with tags, series, and cover images
• 🔒 Secure API Integration: Uses environment variables for API key management
• 🛠️ Easy Integration: Simple setup with uv package manager
• 📊 Comprehensive Logging: Detailed logging for debugging and monitoring

Prerequisites

Before you begin, ensure you have the following installed:

• Python 3.13+
• uv (Python package manager)
• Git (for version control)
• Dev.to API Key (get it from Dev.to Settings)

Installation

1. Install uv (if not already installed)

# On macOS and Linux
curl -LsSf https://astral.sh/uv/install.sh | sh

# On Windows
powershell -c "irm https://astral.sh/uv/install.ps1 | iex"

# Or using pip
pip install uv

2. Clone the Repository

git clone https://github.com/anuragck2/dev-blog-mcp-server.git
cd dev-blog-mcp-server

3. Install Dependencies

# Install project dependencies using uv
uv sync

4. Environment Setup

Create a .env file in the project root:

# Copy the example environment file
cp .env.example .env

# Edit the .env file and add your Dev.to API key
echo "DEVTO_API_KEY=your_devto_api_key_here" > .env

Get your Dev.to API key:

1. Go to Dev.to Settings
2. Scroll down to the "API Keys" section
3. Generate a new API key
4. Copy the key and add it to your .env file

Usage

Running the MCP Server

# Activate the virtual environment and run the server
uv run python main.py

The server will start and listen for MCP connections via stdio transport.

Using with MCP Inspector

The MCP Inspector is a powerful tool for testing and debugging MCP servers. Here's how to set it up:

1. Install MCP Inspector

# Install MCP Inspector globally
npm install -g @modelcontextprotocol/inspector

2. Configure MCP Inspector

Create a configuration file for the MCP Inspector:

{
  "mcpServers": {
    "dev-blog-mcp-server": {
      "command": "uv",
      "args": ["run", "python", "main.py"],
      "cwd": "/path/to/your/dev-blog-mcp-server"
    }
  }
}

3. Run MCP Inspector

# Start the MCP Inspector
mcp-inspector

This will open a web interface where you can:

• Test the publish_blog_to_devto tool
• View server logs
• Debug MCP communication
• Monitor tool execution

Using with Claude Desktop

To use this MCP server with Claude Desktop:

1. Open Claude Desktop Settings
2. Add MCP Server Configuration

Add the following to your Claude Desktop configuration:

{
  "mcpServers": {
    "dev-blog-mcp-server": {
      "command": "uv",
      "args": ["run", "python", "main.py"],
      "cwd": "/path/to/your/dev-blog-mcp-server"
    }
  }
}

3. Restart Claude Desktop

After adding the configuration, restart Claude Desktop to load the new MCP server.

# Test with MCP Inspector
mcp-inspector

Troubleshooting

Common Issues

1. "DEVTO_API_KEY environment variable not set"

   • Ensure your .env file exists and contains the correct API key
   • Verify the API key is valid and has the necessary permissions

2. "Network or API request error"

   • Check your internet connection
   • Verify the Dev.to API is accessible
   • Ensure your API key has not expired

3. MCP Inspector connection issues

   • Verify the server is running
   • Check the configuration file paths
   • Ensure all dependencies are installed

Debug Mode

Enable debug logging by modifying the logging level in main.py:

logging.basicConfig(level=logging.DEBUG, format='%(asctime)s - %(levelname)s - %(message)s')
