Project Introduction

Summary

MCP-Go is the official Go implementation of the Model Context Protocol (MCP). It acts as a bridge, allowing LLM applications to utilize external functions and access current data by providing a structured interface for tool and data source interaction.

Problem Solved

Connecting Large Language Models (LLMs) to real-time external data and tools is complex and often requires custom, ad-hoc solutions. The MCP-Go project solves this by providing a standardized, robust, and easy-to-use protocol implementation in Go, enabling reliable interaction between LLMs and the external environment.

Core Features

MCP Protocol Implementation

Provides a standard way for LLMs to interact with external functions and data, abstracting away complexity.

Go Native Performance

Built natively in Go for efficiency, concurrency, and easy integration into Go-based LLM applications or services.

Extensible Adapter System

Offers a framework for easily developing and registering adapters to connect to various external services (databases, APIs, etc.).

Tech Stack

Go
gRPC
Protocol Buffers
Concurrency Patterns

使用场景

The MCP-Go library can be applied in various scenarios where LLM applications need to interact with the outside world:

Enterprise Chatbots with Real-time Data Access

Details

Build enterprise chatbots that can fetch up-to-date information from internal databases or APIs (e.g., CRM, inventory) to answer user queries.

User Value

Enables chatbots to provide current, accurate information beyond their training data, increasing their utility in business contexts.

LLM-Powered Workflow Automation

Details

Develop LLM-powered agents that can perform actions like sending emails, creating calendar events, or updating records by calling external APIs defined as MCP tools.

User Value

Allows LLMs to be proactive agents, automating tasks and integrating with existing business processes.

Real-time Data Analysis & Monitoring

Details

Integrate LLMs into monitoring or data analysis pipelines where they need to query live system metrics or financial data for analysis or reporting.

User Value

Empowers LLMs to analyze and summarize real-time information streams, providing timely insights.
