MCP Production Server

A production-ready server for building Model Context Protocol (MCP) servers in Python, featuring modules for tools, resources, prompts, JWT authentication, and flexible deployment options.

Features

Core Capabilities

• Modular Architecture: Support for tools, resources, and prompts
• JWT Authentication: Secure Bearer token validation with RS256 encryption
• Multiple Transports: Support for stdio, SSE, and streamable HTTP
• Environment Configuration: Fully configurable via environment variables

Technical Features

• Production Ready: Comprehensive logging, error handling, and Docker support
• FastMCP Integration: Built on the FastMCP framework
• Flexible Deployment: Docker, direct execution, and multiple transport options

Quick Start

Prerequisites

• Python 3.12+
• uv

Installation and Running

# Clone the repository
git clone <repository-url>
cd mcp-production

# Install dependencies
uv sync

# Run with SSE transport (for web-based clients)
uv run fastmcp run --transport sse mcp_server/app.py:mcp

# Or run with stdio transport (for direct MCP clients)
uv run fastmcp run --transport stdio mcp_server/app.py:mcp

# For production with Docker Compose
docker-compose up -d

# Or build and run with Docker directly
# (build the image)
docker build -t mcp-production .
# run the image
docker run -p 8000:8000 -e JWT_PUBLIC_KEY="..." mcp-production

Configuration

Environment Variables

See .env.example for a complete configuration template.

# Server Configuration
MCP_SERVER_NAME=mcp-production
DEBUG=false
HOST=0.0.0.0
PORT=8000
TRANSPORT=sse
LOG_LEVEL=INFO

# JWT Authentication (Optional)
JWT_PUBLIC_KEY="-----BEGIN PUBLIC KEY-----
MIIBIjANBgkqhkiG9w0BAQEFAAOCAQ8AMIIBCgKCAQEA...
-----END PUBLIC KEY-----"

# Or use JWKS URI
JWKS_URI=https://your-auth-provider.com/.well-known/jwks.json

# JWT Validation Settings
JWT_ISSUER=https://your-auth-provider.com
JWT_AUDIENCE=your-mcp-server
REQUIRED_SCOPES=read,write

JWT Authentication

The server supports JWT Bearer token authentication with RS256 encryption. Choose one configuration method:

Static Public Key (for development/testing):

JWT_PUBLIC_KEY="-----BEGIN PUBLIC KEY-----\n...\n-----END PUBLIC KEY-----"
JWT_ISSUER=https://your-auth-provider.com

JWKS URI (recommended for production):

JWKS_URI=https://your-auth-provider.com/.well-known/jwks.json
JWT_ISSUER=https://your-auth-provider.com

Generate test token for development:

from mcp_server.auth import create_test_token
token = create_test_token()

Transport Options

• stdio: Standard input/output (for direct MCP client connections)
• sse: Server-Sent Events (for web-based clients)
• streamable-http: HTTP streaming (for REST-like integrations)
