}
}
}Type safety - Define your tool arguments as native go structs, have mcp-golang handle the rest. Automatic schema generation, deserialization, error handling etc.
Custom transports - Use the built-in transports (stdio for full feature support, HTTP for stateless communication) or write your own.
Low boilerplate - mcp-golang generates all the MCP endpoints for you apart from your tools, prompts and resources.
Modular - The library is split into three components: transport, protocol and server/client. Use them all or take what you need.
Bi-directional - Full support for both server and client implementations through stdio transport.
