Prerequisites

• Python 3.8 or higher
• Claude Code CLI, Gemini CLI, and/or Codex installed
• PyQt6 (optional, for better GUI experience): 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:

# Install py2app (one-time setup)
pip install py2app

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

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

# The app will be created in artifacts/dist/
# You can then:
# 1. Double-click "MCP Config Manager.app" to launch
# 2. Drag it to /Applications for system-wide access
# 3. Add it to your Dock for quick access

Note: The .app bundle is completely self-contained with Python and all dependencies bundled. After code changes, rebuild the app with the same command above.

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

  • 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

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
