🚀 Features
oh-my-mcp provides tools for:
- 📦 Compression (5 tools): ZIP/TAR compression and extraction with security features
- 🌐 Web & Network (18 tools): Web search, page fetching, HTML parsing, downloads, HTTP API client, DNS lookup
- 📁 File System (12 tools): Read, write, search files and directories, file comparison
- 📊 Data Processing (15 tools): JSON, CSV, XML, YAML, TOML parsing and manipulation
- 📝 Text Processing (9 tools): Regex, encoding, email/URL extraction, text similarity
- 💻 System (8 tools): System info, CPU/memory monitoring, environment variables
- 🛠️ Utilities (10 tools): UUID, hashing, date/time operations, math, password generation
- 🤖 Subagent AI (6 tools): Delegate subtasks to external AI models (OpenAI/Anthropic), parallel execution, conditional branching, persistent config
- 🌐 Browser Automation (33 tools): Selenium-based browser control, page navigation, element interaction, screenshots, JavaScript execution, multi-tab management
Note: Python Development, UV Package Manager, and Pylance/Pyright tools have been removed from the packaged version as they require external Python interpreters and package managers. All remaining tools work completely standalone.

⚡ 快速安装与配置
- 安装依赖并开发模式安装:
pip install -e .
- 运行交互式配置向导(推荐):
uv run configure.py
或直接为Claude Desktop生成配置:
python -m mcp_server.cli.config --claude
或启动HTTP配置服务:
python -m mcp_server.cli.config --http-server --port 8765
详细配置说明见:docs/zh/SETUP_GUIDE.md
- 启动MCP服务:
python -m mcp_server.main
启动后可通过Claude Desktop或MCP客户端连接使用。
📦 Installation
Prerequisites
- Python 3.12 or higher
- pip package manager
📚 Tool Reference
For the full list of tools, usage examples, and API details, see docs/en/TOOL_REFERENCE.md.
🔧 Configuration
Logging
Logs are configured in mcp_server/utils.py. You can adjust:
- Log level (INFO, DEBUG, WARNING, ERROR)
- Output destinations (console, file)
- Log format
File Size Limits
File operations have safety limits:
read_file: 10MB max file sizesafe_write_file: Creates parent directories automatically
Security Features
- Path validation: Prevents path traversal attacks
- Safe evaluation: Math expressions only allow safe operations
- Masked values: Sensitive environment variables are masked
- Confirmation required: File deletion requires
confirm=True - Retry logic: Network operations retry up to 3 times
🛡️ Error Handling
All tools include comprehensive error handling:
- ValidationError: Invalid input parameters
- NetworkError: Network request failures
- FileOperationError: File system errors
- DataProcessingError: Data parsing/conversion errors
Errors are returned as JSON with descriptive messages.

Adding New Tools
Create a new tool in the appropriate plugin's handlers.py:
from mcp_server.tools.registry import tool_handler
@tool_handler
def your_tool(param: str) -> str:
"""Tool description.
Args:
param: Parameter description
Returns:
Return value description
"""
try:
# Your implementation
return result
except Exception as e:
logger.error(f"Tool failed: {e}")
return f"Error: {str(e)}"
Testing
Start the server and test tools using an MCP client or the FastMCP testing utilities.

🔧 Configuration Management
Configuration Generator Tool
The python -m mcp_server.cli.config command provides multiple ways to configure MCP clients:
# Quick install to Claude Desktop
python -m mcp_server.cli.config --claude
# Run HTTP server on custom port
python -m mcp_server.cli.config --http-server --port 9000
# Generate config file with custom server name
python -m mcp_server.cli.config --server-name my-tools --output config.json
# Show configuration in console
python -m mcp_server.cli.config --show-config
Configuration Server Endpoints
When running with --http-server:
| Endpoint | Description |
|---|---|
GET /config |
Returns MCP configuration JSON |
GET /info |
Returns server information and paths |
GET /health |
Health check endpoint |
Example usage:
# Start server on port 8765
python -m mcp_server.cli.config --http-server
# Get configuration
curl http://localhost:8765/config
# Get server info
curl http://localhost:8765/info
Enjoy oh-my-mcp! 🚀
