Mcp Config Manager

cat > README.md Click to expand manual installation steps

Prerequisites

• Python 3.8 or higher
• Claude Code CLI, Gemini CLI, and/or Codex installed
• PyQt6 (recommended but optional): Provides rich styling, tooltips, and better UX
• If not installed, app automatically falls back to tkinter (built into Python)
• Install with: pip install PyQt6

Clone and Install

git clone https://github.com/holstein13/mcp-config-manager.git
cd mcp-config-manager
pip install -e .

# Optional: Install PyQt6 for better GUI experience
pip install PyQt6

Development Setup

# Set up development environment
python -m venv venv
source venv/bin/activate  # On Windows: venv\Scripts\activate
pip install -r requirements-dev.txt
pip install -e .

# Run tests
pytest

🚀 Usage

GUI Mode (NEW! - Recommended)

Launch the graphical interface:

mcp-config-manager gui

macOS: Create a Native .app Bundle

For easier launching on macOS, you can create a native .app bundle that can be double-clicked, added to your Dock, or launched via Spotlight.

Initial Setup (One-time)

Due to macOS's externally-managed Python environment (PEP 668), you need to use a virtual environment:

# Create virtual environment
python3 -m venv venv

# Activate virtual environment
source venv/bin/activate

# Install build dependencies
pip install py2app

# Install the application in editable mode
pip install -e .

# Install PyQt6 for GUI support (if not already installed)
pip install PyQt6

Building the .app Bundle

# Activate virtual environment (if not already active)
source venv/bin/activate

# Build the .app bundle (from project root)
./build_app.sh

# Or manually:
python3 scripts/build/setup_app.py py2app --dist-dir artifacts/dist

# Install to Applications folder
cp -r "artifacts/dist/MCP Config Manager.app" /Applications/

The app will be created in artifacts/dist/MCP Config Manager.app. You can then:

1. Double-click "MCP Config Manager.app" to launch
2. Launch via Spotlight (⌘ + Space, type "MCP Config Manager")
3. Add it to your Dock for quick access

Rebuilding After Code Changes

# Activate virtual environment
source venv/bin/activate

# Clean previous build artifacts
rm -rf build artifacts/dist

# Build the .app bundle
./build_app.sh

# Install to Applications folder
cp -r "artifacts/dist/MCP Config Manager.app" /Applications/

Troubleshooting

If the build fails:

• Make sure you're in the virtual environment (source venv/bin/activate)
• Check that all dependencies are installed (pip list)
• Clean build artifacts and try again (rm -rf build artifacts/dist)

If the app crashes on launch:

• Run from terminal to see error messages:

``bash /Applications/MCP\ Config\ Manager.app/Contents/MacOS/MCP\ Config\ Manager ``

Note: The .app bundle is completely self-contained with Python and all dependencies bundled. It works independently of your virtual environment once built.

The GUI provides:

• 🖥️ Visual server list with checkboxes
• ☑ Master checkbox for bulk operations (☐/☑/⊟ states)
• 📝 Server Detail Editor - Click any server to edit its configuration
• 🔧 Dynamic Field Editors - Smart editors for each field type:
• Text fields for strings and commands
• Number fields with validation
• Boolean toggles for true/false values
• Array editors for list management
• Object editors for nested configurations
• 🔍 Project Discovery:
• Discover button scans for project .claude.json files
• Automatically finds MCP servers in your projects
• Smart duplicate detection and consolidation
• Location-aware server management (Global vs Project)
• ✅ Real-time Validation - Immediate feedback on configuration errors
• 🎨 Visual Feedback:
• Blue highlights for selected servers
• Orange indicators for unsaved changes
• Red borders for validation errors
• Empty state guidance when no server selected
• 💾 Backup & Restore:
• Backup button creates timestamped backups
• Restore button lists and restores previous backups
• Automatic backups before any changes
• 🔄 Mode switching between Claude/Gemini/Codex/All
• 💾 Save button with visual feedback
• ➕ Add new servers via JSON with enhanced validation
• 🗑️ Bulk delete servers with confirmation
• 💾 Quick backup and restore with GUI feedback
• 📁 Preset management dialog
• ⌨️ Full keyboard shortcuts (Ctrl+S to save, Esc to cancel)

Interactive CLI Mode

Launch the command-line interactive interface:

mcp-config-manager interactive

This gives you the complete interface from the original mcp_toggle.py script with:

• ✅/❌ Visual server status
• 🔄 Real-time mode switching (Claude/Gemini/Codex/All)
• 📁 Preset management
• ➕ Add servers by pasting JSON
• 🎯 Quick preset modes (minimal, web dev, etc.)

Command Line Usage

# Show current status
mcp-config-manager status

# Enable/disable specific servers
mcp-config-manager enable server-name
mcp-config-manager disable server-name

# Bulk operations
mcp-config-manager enable-all
mcp-config-manager disable-all

# Backup and restore
mcp-config-manager backup           # Create timestamped backup

mcp-config-manager delete-server server-name           # Delete server permanently

# Apply preset modes

mcp-config-manager preset webdev     # + playwright
mcp-config-manager preset fullstack  # + supabase, clerk, railway

# Validate configurations
mcp-config-manager validate ~/.claude.json

Working with Modes

The tool supports four modes:

• Claude only (--mode claude) - Only manages .claude.json
• Gemini only (--mode gemini) - Only manages .gemini/settings.json
• Codex only (--mode codex) - Only manages Codex configurations
• All (synced) (--mode all) - Keeps all configs synchronized

Field Editor System

The field editor system provides dynamic, type-specific editors for server configuration fields:

Architecture

• Base Editor (field_editors/base.py): Abstract base class defining the interface
• Type-Specific Editors: Specialized editors for each data type
• Factory Pattern: FieldEditorFactory creates appropriate editor based on field type
• Validation: Real-time validation with visual feedback

Supported Field Types

1. Text Editor - Single/multi-line text fields for strings and commands
2. Number Editor - Integer/float fields with min/max validation
3. Boolean Editor - Checkbox for true/false values
4. Array Editor - List management with add/remove/reorder capabilities
5. Object Editor - Nested object editing with key-value pairs

Visual Feedback

• Orange Border - Field has been modified (unsaved changes)
• Red Border - Validation error with 2px width
• Light Red Background - Additional error indication (#FFF5F5)
• Tooltip - Error message on hover for invalid fields

Usage Example

# The ServerDetailsPanel automatically creates appropriate editors
field_editor = FieldEditorFactory.create_editor(
    field_name="command",
    field_value="npx @modelcontextprotocol/server-sqlite",
    field_type="string",
    parent=self
)

# Connect signals for change tracking
field_editor.value_changed.connect(self.on_field_changed)
field_editor.validation_error.connect(self.on_validation_error)

• Same functionality - All original features are available in interactive mode
• Enhanced capabilities - Plus new CLI commands and better error handling
