MCP Server Sample

What is MCP Server Sample?

MCP Server Sample is a basic implementation of a server conforming to the Model Context Protocol (MCP). MCP enables communication between AI models and locally running MCP servers. This sample provides core infrastructure for handling JSON messages via standard input/output, defining MCP types, and managing basic error handling. It is intended for developers who want to build custom MCP servers or learn the protocol.

How to use MCP Server Sample?

Clone the repository, install dependencies with go mod tidy, and then run the server with go run main.go. The server reads JSON requests from stdin and writes JSON responses to stdout.

Key features of MCP Server Sample

• Processes JSON messages via standard input/output
• Conforms to basic MCP protocol type definitions
• Built-in error handling for server responses
• Server information and capabilities management structures
• Extensible architecture for adding tools, resources, and handlers

Use cases of MCP Server Sample

• Starting template for building custom MCP-compliant servers
• Learning and prototyping the MCP protocol
• Experimenting with tool and resource definitions in Go
• Base for integrating AI models with local services via MCP
