📦 MCP Manager | 🌉 MCP Bridge

Desktop application for managing MCP servers | VS Code/Cursor extension bridge

🎯 What is This?

This is an MCP server built on the @tscodex/mcp-sdk that provides powerful image processing capabilities. It can work in two ways:

1. Standalone Mode: Run directly via npx or npm, passing environment variables and configuration

2. Managed Mode: Use with MCP Manager for workspace isolation, visual configuration, and seamless integration with Cursor

Architecture Overview

How It Works

The Problem: Real projects require each Cursor workspace to work with its own workspace context. For example, this image server needs the root path of the current project to create and work with images. But you can't run a separate server instance for each project.

The Solution: MCP Manager allows you to:

• Run one server instance (e.g., @tscodex/mcp-images)

• Create multiple workspace proxies that forward requests with workspace context

• The SDK receives headers from the current workspace and allows one server to work with different workspaces

The Bridge: MCP Manager Bridge automatically:

• Registers the workspace in MCP Manager by project path

• Syncs Cursor with the manager

• Registers proxy MCP servers in local mcp.json

• Provides perfect encapsulation and connection between workspaces

🎨 Features

• 🖼️ Image Processing: Resize, crop, optimize, convert formats, apply filters, rotate, watermark

• 🔍 Stock Image Search: Search and download images from Pexels and Pixabay

• 🤖 AI Image Generation: Generate images using OpenAI DALL-E

• 🎨 Color Extraction: Extract dominant colors and generate color palettes

• 📦 Multiple Formats: Support for WebP, JPEG, PNG, AVIF

• ⚡ High Performance: Powered by Sharp for fast image processing

📦 Installation

Option 1: Standalone (via npx)

Option 2: Global Installation

Option 3: Managed Mode (Recommended)

Use with MCP Manager for the best experience:

1. Install MCP Manager: Download from GitHub Releases

2. Install Bridge Extension: MCP Manager Bridge from VS Code Marketplace

3. Add Server: In MCP Manager, add @tscodex/mcp-images as a new server

4. Configure: Use the visual UI to configure the server (JSON Schema-based)

5. Enable: Enable the server for your workspace in Cursor

Benefits of Managed Mode:

• ✅ Visual Configuration: No need to edit JSON files manually

• ✅ Workspace Isolation: Each project gets its own workspace proxy

• ✅ Secure Secrets: 3-level secret override (Global → Workspace → Server)

• ✅ Permissions Control: Granular control over what each server can access

• ✅ AI Agent Integration: Use AI agents without exposing API keys to servers

• ✅ Token Statistics: Track AI usage transparently

• ✅ Auto-sync: Bridge automatically syncs with Cursor

🚀 Quick Start

Standalone Mode

Managed Mode

1. Start MCP Manager desktop application

2. Open Cursor with your project

3. Bridge Extension automatically:

   • Registers your workspace

   • Connects to MCP Manager

   • Syncs enabled servers to Cursor's mcp.json

4. Enable Server: Click the play icon on @tscodex/mcp-images in the Bridge panel

5. Configure: Use MCP Manager UI to configure the server (if needed)

⚙️ Configuration

Configuration File

Create .mcp-images.json in your project root:

Configuration Options:

• root (string, optional): Project root directory

  • Use "." to use MCP_PROJECT_ROOT environment variable (managed mode)

  • Use absolute path for standalone mode

• defaultProvider ("pexels" | "pixabay" | "openai" | "auto", default: "auto"): Default image provider

• defaultFormat ("webp" | "jpeg" | "png" | "avif", default: "webp"): Default image format

• defaultMaxWidth (number, default: 1920): Default maximum width (1-10000)

• defaultQuality (number, default: 80): Default quality (1-100)

• saveMetadata (boolean, default: true): Save JSON metadata alongside images

• embedExif (boolean, default: false): Embed metadata in EXIF data

Secrets Management

⚠️ Security Note: API keys are stored as secrets (environment variables with SECRET_ prefix) instead of in configuration files.

In Standalone Mode:

In Managed Mode: MCP Manager provides a 3-level secret override system:

1. Global: Secrets available to all servers

2. Workspace: Secrets specific to a workspace

3. Server: Secrets specific to a server instance

This allows fine-grained control over what secrets each server can access.

🔒 Security & Permissions

Security Features

MCP Manager provides enterprise-grade security:

1. OS Keychain Storage: Secrets are stored in the operating system's secure keychain (Windows Credential Manager, macOS Keychain, Linux Secret Service)

2. No Key Exposure: API keys are never passed directly to MCP servers. Servers that need AI access use the AI Agent proxy mechanism

3. Process Isolation: Each server runs in its own process with isolated environment

4. Permission System: Granular control over what each server can access

Permissions System

MCP Manager's permission system allows you to configure:

• Environment Variables: Which environment variables are available to the server

• Secrets Access: Which secrets the server can access

• AI Agent Access: Whether the server can use the AI Agent proxy

• File System Access: Workspace root access (always scoped to project)

Example Permission Configuration:

🤖 AI Agent Integration

MCP Manager includes a built-in AI Agent that:

1. Registers OpenAI-compatible APIs: Configure via baseUrl and API key

2. Provides Proxy: Servers can use AI without direct API key access

3. Token Statistics: Track all AI usage transparently

4. Permission-Based: Each server must have AI Agent access enabled in permissions

How It Works:

1. Register AI Provider in MCP Manager:

   • Base URL: https://api.openai.com/v1

   • API Key: (stored securely in OS keychain)

   • Model: gpt-4, gpt-3.5-turbo, etc.

2. Enable for Server: In server permissions, enable AI Agent access

3. Use in Server: The SDK provides methods to access the AI Agent:

   const aiResponse = await server.getAiAgent().chat({ model: 'gpt-4', messages: [{ role: 'user', content: 'Generate image prompt' }] });

4. Track Usage: All token usage is tracked and displayed in MCP Manager

Benefits:

• ✅ No API keys exposed to servers

• ✅ Centralized AI usage tracking

• ✅ Easy to switch AI providers

• ✅ Cost monitoring
