MCP C# Code Server

Description

McpServer is an ASP.NET Core implementation of a Model Context Protocol (MCP) server that exposes tools for working with C# code, including a semantic search tool that queries a remote search API and falls back to a local repository scan if needed. It offers strongly typed request/response models, resilient HTTP client handling, and source-generated JSON serialization for efficient communication. The server is easily extensible with new MCP tools and integrates seamlessly with MCP-enabled clients.
