StackOverflow MCP Server

A Model Context Protocol (MCP) server that provides seamless access to StackOverflow's programming Q&A database using the FastMCP framework. This package serves as an NPX-compatible wrapper for the Python-based StackOverflow MCP server.

Quick Start

Using NPX (Recommended)

# Run directly with npx (no installation required)
npx @notalk/stackoverflow-mcp

# Skip installation prompts (useful for automation)
npx -y @notalk/stackoverflow-mcp

# Or install globally
npm install -g @notalk/stackoverflow-mcp
stackoverflow-mcp

Using Python Module Directly

# If you have the Python package installed
python -m stackoverflow_mcp

# Using uv (recommended for Python development)
uv run python -m stackoverflow_mcp

📋 Prerequisites

• Node.js 14.0.0 or higher
• Python 3.12 or higher
• uv (recommended) or pip (Python package manager)

The NPX wrapper will automatically:

• Detect your Python installation
• Install the required Python package (stackoverflow-mcp)
• Handle environment setup and configuration

Installation

Option 1: NPX (No Installation)

npx @notalk/stackoverflow-mcp --help

Option 2: Global NPM Installation

npm install -g @notalk/stackoverflow-mcp
stackoverflow-mcp --help

Option 3: Local Development

git clone https://github.com/NoTalkTech/stackoverflow-mcp.git
cd stackoverflow-mcp
npm install
node cli.js --help

🎯 Features

• 🔍 Question Search: Search StackOverflow questions by keywords
• 📖 Question Details: Get detailed question content, answers, and metadata
• 🏷️ Tag-based Search: Find questions by programming language tags
• ⚡ Rate Limit Management: Automatic detection and handling of API limits
• 🔐 API Authentication: Support for StackOverflow API keys
• 🚀 Auto-deployment: NPX-compatible with automatic Python environment setup
• 📁 Smart Configuration: Auto-discovery of config files and working directories
• 🔧 Development Mode: Enhanced logging and debugging features
• ⚡ FastMCP Implementation: Simplified, elegant server using FastMCP framework (only implementation)

Usage

Basic Usage

# Start the MCP server with default settings
npx @notalk/stackoverflow-mcp

# Auto-confirm installation (useful for scripts/CI)
npx -y @notalk/stackoverflow-mcp

# Start on a specific port
npx @notalk/stackoverflow-mcp --port 8080

# Development mode with debug logging
npx @notalk/stackoverflow-mcp --dev --log-level DEBUG

# Use custom configuration file
npx @notalk/stackoverflow-mcp --config-file ./my-config.json

Python Development with uv

For Python development, we recommend using uv for faster dependency management:

# Install dependencies with uv
uv sync

# Run the server with uv
uv run python -m stackoverflow_mcp

# Development mode with uv
uv run python -m stackoverflow_mcp --log-level DEBUG

FastMCP Benefits:

• 🔥 Simplified Code: Clean, maintainable implementation
• 🎯 Decorator-based: Clean tool registration with @mcp.tool()
• 🚀 Auto-schema: Type hints automatically generate schemas
• 🛡️ Built-in Error Handling: Consistent error responses
• 📦 Better Separation: Clean architecture with focused responsibilities

Configuration

Create a .stackoverflow-mcp.json file in your project directory:

{
  "host": "localhost",
  "port": 3000,
  "log_level": "INFO",
  "stackoverflow_api_key": "your_api_key_here"
}

Command Line Options

Options:
  --host TEXT                     Host to bind the server to
  --port INTEGER                  Port to bind the server to (auto-detect if not specified)
  --log-level [DEBUG|INFO|WARNING|ERROR]
                                  Logging level
  --config-file PATH              Path to configuration file (auto-discover if not specified)
  --working-dir DIRECTORY         Working directory (auto-detect if not specified)
  --auto-port / --no-auto-port    Automatically find an available port if specified port is in use
  --dev / --prod                  Run in development mode (more verbose logging, auto-reload)
  --health-check / --no-health-check
                                  Enable startup health checks
  --version                       Show the version and exit.
  --help                          Show this message and exit.

🔧 Configuration Files

The server automatically discovers configuration files in the following order:

1. .stackoverflow-mcp.json
2. stackoverflow-mcp.config.json
3. config/stackoverflow-mcp.json
4. .config/stackoverflow-mcp.json

Example Configuration

{
  "host": "localhost",
  "port": 3000,
  "log_level": "INFO",
  "stackoverflow_api_key": "your_optional_api_key",
  "max_requests_per_minute": 30,
  "enable_caching": true
}

🌐 API Endpoints

Once running, the MCP server provides the following tools:

• search_questions: Search StackOverflow questions by keywords
• get_question_details: Get detailed information about a specific question
• search_by_tags: Find questions filtered by programming language tags
• get_user_info: Get information about StackOverflow users
