Overview

MCP Bridge is a robust proxy solution designed to transform STDIO-based MCP (Model Context Protocol) servers into web-accessible services. It leverages Server-Sent Events (SSE) or streamable HTTP transport, making it ideal for modern deployment scenarios where traditional STDIO communication is not feasible - e.g vercel.

Addressing Deployment Challenges

🚫 Overcoming Limitations

• Serverless Environments: STDIO communication is often incompatible with serverless platforms like Vercel. MCP Bridge eliminates this barrier.
• Limited Transport Options: Moves beyond the constraints of traditional WebSocket adapters, offering broader transport compatibility.
• Infrastructure Restrictions: Provides a solution for environments that do not natively support STDIO-based communication.

⚙️ Enabling Flexible Transport

• Facilitates deployment on platforms that lack native STDIO support.
• Offers versatile transport options, adapting to diverse environmental requirements.

Why MCP Bridge is Essential

Do you want to self-host MCP servers for your favorite AI applications or chatbots? MCP Bridge is the perfect tool! By using MCP Bridge, optionally combined with services like Cloudflare Tunnel, you can establish a globally accessible MCP server 🌍.

🎯 Key Use Cases

• Self-Hosting: Easily host MCP servers for personal or project-based AI applications.
• Global Accessibility: Make local MCP servers available from anywhere.
• Web Application Integration: Seamlessly integrate with web-based AI applications.
• Platform Compatibility: Bypass specific platform communication limitations.

Key Features

🎛️ Management UI

• An intuitive web interface for effortlessly adding and managing MCP servers.
• Visual configuration tools for streamlined setup.

🔗 Connection and Config Generator

• Automates the generation of MCP server connection configurations.
• Provides copy-paste-ready connection strings.
• Supports multiple transport protocols for versatile integration.

⚡ Easy Setup

• A streamlined installation process for quick deployment.
• Requires minimal configuration to get started.
• Designed for rapid deployment across various platforms.

🔄 Protocol Translation

• Seamlessly converts STDIO-based communication to SSE/HTTP.
• Ensures full MCP protocol compatibility throughout the translation.
• Efficiently handles message routing and processing.

Getting Started

To get started with MCP Bridge, follow these simple steps:

1. Install Dependencies:

   bun i
   

2. Start Database Services (PostgreSQL & Redis):

   bun docker:pg
   bun docker:redis
   

   (These commands will initialize and run PostgreSQL and Redis containers via Docker.)
3. Apply Database Migrations:

   bun db:push
   

   (This command will synchronize your database schema.)

Roadmap
