Go MCP Server
Build MCP servers in Go with a high-level, minimal boilerplate framework.
Data last scanned today · Reviewed today
Overview
This Go-based implementation of the Model Context Protocol (MCP) provides a high-level SDK designed for building custom tools, resources, and prompts. By abstracting away complex protocol details and server management, it allows developers to define handlers and tool capabilities directly within their Go codebases. The framework is intended for developers who prefer Go for their infrastructure and wish to expose functionality to LLM applications. It supports the creation of stdio-based servers, facilitating communication between AI assistants and local tools or external data sources.
Our verdict
With a security score of 53/100, this project is classified as high-risk. This is primarily because the tool has not yet undergone editorial review regarding critical areas like read-only mode support and authentication methods. While it benefits from a large community of 100 contributors and 9,081 stars, users should exercise caution in sensitive environments until these security implementation details are formally verified and reviewed.
- Zero direct dependencies reduce the supply-chain attack surface
- Maintains an active development cycle with recent code commits
- Benefits from a large community with 100 individual contributors
- Includes documentation and video tutorials for onboarding
- Authentication methods remain unreviewed for security vulnerabilities
- Read-only mode support has not yet been editorially verified
- Lacks an official vendor-backed maintenance structure
