JSON-RPC 2.0

MCP-Scala is a JSON-RPC 2.0 server implementation developed by windymelt that enables AI assistants to interact with remote procedure calls through a standardized protocol. Built with Scala 3 and leveraging the Cats Effect library for functional programming, it provides a type-safe interface for method handling, parameter validation, and response formatting. The server supports various JSON-RPC features including positional and named parameters, notifications, batch requests, and comprehensive error handling. This implementation is particularly useful for developers who need a robust, type-safe bridge between AI systems and backend services where structured communication is essential.
