MCP Environment & Installation Manager

A unified control center for managing MCP servers and their configurations. This MCP server provides tooling for environment variable management, profile-based configurations, and local package installation automation.

Features

Environment Variable Management: Securely store and manage environment variables for your MCP servers
Profile System: Create different profiles for different projects or environments
Local Package Installation: Automatically install MCP packages locally
Configuration Watching: Monitor MCP configurations and adapt to changes
Auto-Configuration: Automatically update configurations to use locally installed packages

Installation

Node.js Installation

# Global installation
npm install -g @devlimelabs/mcp-env-manager

# Or using yarn
yarn global add @devlimelabs/mcp-env-manager

# Or using pnpm
pnpm add -g @devlimelabs/mcp-env-manager

Docker Installation

# Clone the repository
git clone https://github.com/devlimelabs/master-mcps.git
cd master-mcps/packages/mcp-env-manager

# Build and run with Docker
npm run docker:build
npm run docker:run

# Or using Docker Compose
npm run compose:up

Configuration

Create a .env file based on the .env.example template:

# Copy the example configuration
cp .env.example .env

# Edit the configuration
nano .env

Important Environment Variables

MCP_ENV_ENCRYPTION_KEY: Required for encrypting sensitive values
MCP_ENV_STORAGE_DIR: Directory for storing configuration (default: ~/.mcp-env-manager)

Usage

Command Line Interface

# Start the MCP server with stdio transport (for Claude, Cursor integration)
mcp-env-manager

# Start with SSE transport (for web integration)
mcp-env-manager --sse --port 3000

With Claude for Desktop

Run the provided setup script:

npm run setup:claude

Or manually add the Environment Manager to your Claude for Desktop configuration file:

{
  "mcpServers": {
    "env-manager": {
      "command": "mcp-env-manager",
      "displayName": "Environment & Installation Manager"
    }
  }
}

Restart Claude for Desktop and start using the Environment Manager tools.

With Cursor

Add the Environment Manager to your Cursor MCP configuration file:

{
  "mcpServers": {
    "env-manager": {
      "command": "mcp-env-manager"
    }
  }
}

Tool Examples

Managing Environment Profiles

> create-profile
  name: "Development Environment"
  description: "Configuration for local development"

> list-profiles

Managing Environment Variables

> set-env-var
  profileId: "development-environment-12345"
  key: "API_KEY"
  value: "your-api-key-here"
  sensitive: true

> list-env-vars
  profileId: "development-environment-12345"

> activate-profile
  profileId: "development-environment-12345"

Managing MCP Installations

> install-mcp
  packageName: "@modelcontextprotocol/server-filesystem"

> list-installed-mcps

> update-mcp
  packageName: "@modelcontextprotocol/server-filesystem"

Configuration Watching

> configure-watcher
  watchClaude: true
  watchCursor: true

> enable-auto-localize
  enabled: true

Development

# Install dependencies
npm install

# Start in development mode
npm run dev

# Run tests
npm test

# Build the package
npm run build

Known Limitations and Future Improvements

SSE Transport: The current SSE transport implementation is incomplete and falls back to stdio. Further work is needed to make it fully functional for web integrations.
Testing: The MCP server communicates via JSON-RPC over stdio which makes automated testing more complex. See testing_guide.md for manual testing procedures.
Package Installation: Package installation depends on the local Node.js environment and should be tested with actual MCP packages.

Running Manual Tests

For manual testing details, see the Testing Guide.

Docker Deployment

The package includes a multi-stage Dockerfile and docker-compose.yml for easy deployment:

# Start the service with Docker Compose
docker-compose up -d

# View logs
docker-compose logs -f

# Stop the service
docker-compose down

Security Considerations

The MCP_ENV_ENCRYPTION_KEY should be kept secure and not committed to version control
Sensitive values are encrypted at rest using the provided encryption key
Use a strong, randomly-generated encryption key for production environments
