mcp-optimizer 0.3.9

Mathematical optimization MCP server with PuLP and OR-Tools support

MCP Optimizer

🚀 Mathematical Optimization MCP Server with PuLP and OR-Tools support

🚀 Quick Start

Integration with LLM Clients

Claude Desktop Integration

Option 1: Using uvx (Recommended)

1. Install Claude Desktop from claude.ai
2. Open Claude Desktop → Settings → Developer → Edit Config
3. Add to your claude_desktop_config.json:

{
  "mcpServers": {
    "mcp-optimizer": {
      "command": "uvx",
      "args": ["mcp-optimizer"]
    }
  }
}

4. Restart Claude Desktop and look for the 🔨 tools icon

Option 2: Using pip

pip install mcp-optimizer

Then add to your Claude Desktop config:

{
  "mcpServers": {
    "mcp-optimizer": {
      "command": "mcp-optimizer"
    }
  }
}

Option 3: Using Docker

Method A: Docker with STDIO transport (Recommended for MCP clients)

docker pull ghcr.io/dmitryanchikov/mcp-optimizer:latest

Then add to your Claude Desktop config:

{
  "mcpServers": {
    "mcp-optimizer": {
      "command": "docker",
      "args": [
        "run", "--rm", "-i",
        "ghcr.io/dmitryanchikov/mcp-optimizer:latest",
        "python", "main.py"
      ]
    }
  }
}

Method B: Docker with SSE transport (for HTTP/web clients)

# Run SSE server on port 8000
docker run -d -p 8000:8000 ghcr.io/dmitryanchikov/mcp-optimizer:latest \
  python -m mcp_optimizer.main --transport sse --host 0.0.0.0

# Or with custom port
docker run -d -p 9000:9000 ghcr.io/dmitryanchikov/mcp-optimizer:latest \
  python -m mcp_optimizer.main --transport sse --host 0.0.0.0 --port 9000

Then use HTTP client to connect to http://localhost:8000 (requires additional MCP HTTP client setup)

Cursor Integration

1. Install the MCP extension in Cursor
2. Add mcp-optimizer to your workspace settings:

{
  "mcp.servers": {
    "mcp-optimizer": {
      "command": "uvx",
      "args": ["mcp-optimizer"]
    }
  }
}

Other LLM Clients

For other MCP-compatible clients (Continue, Cody, etc.), use similar configuration patterns with the appropriate command for your installation method.

Advanced Installation Options

Local Development

# Clone the repository
git clone https://github.com/dmitryanchikov/mcp-optimizer.git
cd mcp-optimizer

# Install dependencies with uv
uv sync --extra dev

# Run the server
uv run python main.py

Local Package Build and Run

For testing and development, you can build the package locally and run it with uvx:

# Build the package locally
uv build

# Run with uvx from local wheel file
uvx --from ./dist/mcp_optimizer-0.3.9-py3-none-any.whl mcp-optimizer

# Or run with help to see available options
uvx --from ./dist/mcp_optimizer-0.3.9-py3-none-any.whl mcp-optimizer --help

# Test the local package with a simple MCP message
echo '{"jsonrpc": "2.0", "method": "initialize", "params": {"protocolVersion": "2024-11-05", "capabilities": {}, "clientInfo": {"name": "test", "version": "1.0"}}, "id": 1}' | uvx --from ./dist/mcp_optimizer-0.3.9-py3-none-any.whl mcp-optimizer

Note: The local build creates both wheel (.whl) and source distribution (.tar.gz) files in the dist/ directory. The wheel file is recommended for uvx installation as it's faster and doesn't require compilation.

Troubleshooting: If you encounter event loop issues when using uvx, the package includes automatic detection and handling of existing event loops using nest-asyncio.

Docker with Custom Configuration

# Build locally with optimization
git clone https://github.com/dmitryanchikov/mcp-optimizer.git
cd mcp-optimizer
docker build -t mcp-optimizer:optimized .
docker run -p 8000:8000 mcp-optimizer:optimized

# Check optimized image size (398MB vs 1.03GB original - 61% reduction!)
docker images mcp-optimizer:optimized

# Test the optimized image
./scripts/test_docker_optimization.sh

Standalone Server Commands

# Run directly with uvx (no installation needed)
uvx mcp-optimizer

# Or run specific commands
uvx mcp-optimizer --help

# With pip installation
mcp-optimizer

# Or run with Python module (use main.py for stdio mode)
python main.py

Transport Modes

MCP Optimizer supports two transport protocols:

• STDIO: Standard input/output for direct MCP client integration (Claude Desktop, Cursor, etc.)
• SSE: Server-Sent Events over HTTP for web-based clients and custom integrations

STDIO Transport (Default - for MCP clients like Claude Desktop)

# Default STDIO mode for MCP protocol
uvx mcp-optimizer
# or
uvx mcp-optimizer --transport stdio
# or
uv run python -m mcp_optimizer.main --transport stdio
# or
python main.py

SSE Transport (for HTTP/web clients)

# SSE mode for HTTP clients (default port 8000)
uvx mcp-optimizer --transport sse
# or
uv run python -m mcp_optimizer.main --transport sse

# Custom host and port
uvx mcp-optimizer --transport sse --host 0.0.0.0 --port 9000
# or
uv run python -m mcp_optimizer.main --transport sse --host 0.0.0.0 --port 9000

# With debug mode
uvx mcp-optimizer --transport sse --debug --log-level DEBUG

Available CLI Options

# Show all available options
uvx mcp-optimizer --help

# Options:
#   --transport {stdio,sse}    MCP transport protocol (default: stdio)
#   --port PORT               Port for SSE transport (default: 8000)
#   --host HOST               Host for SSE transport (default: 127.0.0.1)
#   --debug                   Enable debug mode
#   --reload                  Enable auto-reload for development
#   --log-level {DEBUG,INFO,WARNING,ERROR}  Logging level (default: INFO)
