What is MCP Gateway Go?
MCP Gateway Go is a lightweight gateway tool based on the Go language. It can convert Model Context Protocol (MCP) servers with standard input/output to HTTP endpoints that support Server-Sent Events (SSE). This enables clients such as web browsers or AI agents to communicate with MCP servers in real-time via the HTTP protocol.How to use MCP Gateway Go?
After installation, you can start the gateway service through simple command-line operations. Configure the port, base URL, and the command of the MCP server to connect to, and you can quickly set up a real-time communication service.Applicable scenarios
It is suitable for scenarios where command-line tools or local services need to be quickly converted into web-accessible APIs, especially for AI agent development, real-time data monitoring, and web application integration.Main features
Real-time communication conversionConvert the MCP protocol with standard input/output to the web-friendly SSE protocol
Lightweight gatewayDeveloped based on the Go language, with low resource consumption and fast startup
Security authenticationSupports OAuth2 Bearer Token authentication to ensure communication security
Flexible configurationYou can customize parameters such as ports and URL paths to adapt to different deployment environments
Advantages and limitations
Advantages
Easy to use: Deployment can be completed with a single command
Cross-platform: Based on the Go language, it can run on multiple operating systems
Low latency: Real-time conversion of the MCP protocol to SSE with quick response
Lightweight: Does not rely on complex middleware and has low resource consumption
Limitations
Only supports one-way communication (SSE from the server to the client)
Requires the pre-installation of the Go runtime environment
Advanced features such as load balancing require additional configuration
How to use
Installation
