ken-mcp 3.5.0

MCP server generator with modular architecture for creating FastMCP servers from natural language requirements

KEN-MCP 🏗️ - Universal MCP Server Generator

KEN-MCP is a powerful MCP (Model Context Protocol) server generator that creates complete, production-ready MCP servers from natural language descriptions. It works for ANY type of MCP - not just APIs!

Features

• 🎯 Universal Generation: Creates MCP servers for any purpose - productivity tools, data processing, utilities, creative tools, and more
• 🤖 AI-Powered: Uses Claude's capabilities to understand requirements and generate appropriate implementations
• 📦 Complete Projects: Generates full project structure with server code, documentation, and configuration
• ✅ Production Ready: Includes proper error handling, type hints, and validation
• 📚 Well Documented: Auto-generates comprehensive README and documentation

Installation

KEN-MCP is an MCP server that runs within Claude Desktop. To install:

1. Add to your Claude Desktop configuration:

{
  "mcpServers": {
    "KEN-MCP": {
      "command": "python",
      "args": ["/path/to/KEN-MCP/server.py"]
    }
  }
}

2. Restart Claude Desktop

Usage

Simply describe what kind of MCP server you want:

Generate an MCP server that:
- Manages todo lists with priorities
- Tracks deadlines
- Can mark items as complete

KEN-MCP will create a complete MCP server with all the necessary tools, proper error handling, and documentation.

Examples

• Productivity: "I want an MCP that manages todo lists with priorities and deadlines"
• Development: "Create an MCP for generating git commit messages based on code changes"
• Data: "Build an MCP that can analyze CSV files and generate statistics"
• Utilities: "I need an MCP for converting between different text encodings"
• Creative: "Make an MCP that generates creative writing prompts"

How It Works

1. Analyze Requirements: KEN-MCP uses AI to understand your natural language description
2. Plan Implementation: Creates a detailed plan with tools, resources, and prompts
3. Generate Code: Produces complete, working FastMCP server implementation
4. Create Documentation: Generates README, usage guides, and configuration instructions
5. Validate: Ensures the generated code is syntactically correct and complete

Generated Projects

Each generated MCP server includes:

• server.py - The main MCP server implementation
• README.md - Comprehensive documentation
• mcp.md - Technical details and architecture
• pyproject.toml - Python package configuration
• .gitignore - Version control setup

Requirements

• Python 3.10+
• FastMCP framework (automatically included in generated projects)

Troubleshooting Generated MCPs

When Claude Code Shows "Failed"

When adding an MCP to Claude Code, if you see a generic "Failed" error, you need to diagnose the issue systematically.

Step 1: Check if MCP is Active

After adding an MCP, verify it's working:

# List all MCPs
claude mcp list

# Look for your MCP in the output. It should show:
# ✓ your-mcp-name    Active    python3 /path/to/your-mcp/server.py
# ✗ your-mcp-name    Failed    python3 /path/to/your-mcp/server.py

Step 2: Test the MCP Manually

Before troubleshooting Claude Code, ensure the MCP works standalone:

# Navigate to your MCP directory
cd /path/to/your-mcp

# Test the server directly
python3 server.py

# Expected output: "Server started on stdio"
# If you see errors here, fix them first!

Step 3: Remove and Re-add the MCP

If the MCP shows as "Failed":

# Remove the MCP
claude mcp remove your-mcp-name

# IMPORTANT: Restart Claude Code after removal
claude

# Re-add with correct configuration
claude mcp add your-mcp-name "python3 /path/to/your-mcp/server.py"

# IMPORTANT: Restart Claude Code again
claude

Common Causes of "Failed" Status

Since Claude Code only shows "Failed" without details, try these fixes in order:

1. Wrong Python Command (Most Common)

Diagnosis: Run which python3 to find your Python path

Fix: Try these commands in order when adding the MCP:

# First, find your Python:
which python3
# Example output: /usr/bin/python3

# Try 1: Use python3
claude mcp remove your-mcp-name
claude  # Restart
claude mcp add your-mcp-name "python3 /path/to/your-mcp/server.py"
claude  # Restart

# Try 2: Use full path from 'which' command
claude mcp remove your-mcp-name
claude  # Restart
claude mcp add your-mcp-name "/usr/bin/python3 /path/to/your-mcp/server.py"
claude  # Restart

# Try 3: Use specific version
claude mcp remove your-mcp-name
claude  # Restart
claude mcp add your-mcp-name "python3.11 /path/to/your-mcp/server.py"
claude  # Restart

2. Missing Dependencies

Diagnosis: Test manually with cd /path/to/your-mcp && python3 server.py

Fix: Install dependencies in the correct Python environment:

# Navigate to the MCP directory
cd /path/to/your-mcp

# Install with the same Python you're using in Claude
python3 -m pip install -e .

# Then re-add the MCP
claude mcp remove your-mcp-name
claude  # Restart
claude mcp add your-mcp-name "python3 /path/to/your-mcp/server.py"
claude  # Restart

3. Wrong File Path

Diagnosis: Check if server.py exists at the path you specified

Fix: Verify the exact path:

# Find the correct server.py location
find /path/to/your-mcp -name "server.py"

# Use the exact path when adding
claude mcp remove your-mcp-name
claude  # Restart
claude mcp add your-mcp-name "python3 /exact/path/to/server.py"
claude  # Restart

Quick Diagnostic Checklist

When you see "Failed" status, run through this checklist:

1. Test manually first:

   cd /path/to/your-mcp
   python3 server.py
   # Should output: "Server started on stdio"
   

2. Check Python path:

   which python3
   # Use this exact path when adding MCP
   

3. Verify dependencies installed:

   python3 -m pip list | grep fastmcp
   # Should show: fastmcp 0.1.0 or higher
   

4. Check file permissions:

   ls -la /path/to/your-mcp/server.py
   # Should be readable/executable
   

5. Try virtual environment:

   cd /path/to/your-mcp
   python3 -m venv venv
   source venv/bin/activate
   pip install -e .
   # Then use: /path/to/your-mcp/venv/bin/python
   

Managing MCPs in Claude Code

Adding an MCP

# Add the MCP
claude mcp add mcp-name "python3 /path/to/server.py"

# ALWAYS restart Claude Code after adding
claude

# Check if it's active
claude mcp list
# Should show: ✓ mcp-name    Active

Removing an MCP

# Remove the MCP
claude mcp remove mcp-name

# ALWAYS restart Claude Code after removing
claude

# Verify it's removed
claude mcp list
# Should not show the MCP anymore

Updating an MCP

# Remove old version
claude mcp remove mcp-name
claude  # Restart

# Add updated version
claude mcp add mcp-name "python3 /path/to/updated/server.py"
claude  # Restart

Important Notes

1. Always restart Claude Code after any MCP changes using the claude command
2. "Failed" status is generic - you must diagnose by testing manually
3. Python environment matters - the Python used by Claude must have all dependencies installed
4. Use absolute paths - always use full paths like /Users/you/project/server.py
5. Check permissions - ensure Claude can read and execute your files

For Claude Code: MCP Troubleshooting Protocol

If you are Claude Code helping a user with a failed MCP, follow this systematic process:

Required Commands to Run

1. Always check MCP status first:

   claude mcp list
   

2. Test the MCP manually before any fixes:

   cd /path/to/mcp-directory
   python3 server.py
   # Expected: "Server started on stdio"
   

3. After any configuration change, ALWAYS:

   claude mcp remove mcp-name
   # Tell user: "Please EXIT Claude Code (type 'exit' or Ctrl+C) and restart with 'claude'"
   # Wait for confirmation before proceeding
   claude mcp add mcp-name "python3 /absolute/path/to/server.py"
   # Tell user: "Please EXIT Claude Code (type 'exit' or Ctrl+C) and restart with 'claude'"
   # Wait for confirmation before proceeding
   claude mcp list  # Verify it's now Active
   

Critical Points

• Gather system info first - run comprehensive system analysis to understand user's Python setup
• Never skip manual testing - if python3 server.py doesn't work, fix that first
• Always request EXIT and restart - tell user "Please EXIT Claude Code (type 'exit' or Ctrl+C) and restart with 'claude'" after every add/remove
• Use system-specific Python paths - use the exact Python path found in system analysis
• Fix dependencies first - run python3 -m pip install -e . in the MCP directory if imports fail
• "Failed" is generic - you must diagnose by testing the MCP manually
• Be specific about user's system - reference their OS, Python version, and paths in explanations
