SharpTools
Built around the Roslyn compiler platform, this server gives Claude surgical C# codebase modification capabilities that go way beyond text manipulation. You get precise member addition, symbol renaming with reference updates, FQN-based navigation, and automatic Git branching for every change. It can pull source code from SourceLink, decompile assemblies when needed, and handles complexity analysis through the same APIs Visual Studio uses. The author runs it standalone as a complete coding assistant, and it's designed to work with any .NET project from Framework to modern versions. Includes custom prompts for GitHub Copilot integration.

SharpTools: Roslyn Powered C# Analysis & Modification MCP Server
SharpTools is a robust service designed to empower AI agents with advanced capabilities for understanding, analyzing, and modifying C# codebases. It leverages the .NET Compiler Platform (Roslyn) to provide deep static analysis and precise code manipulation, going far beyond simple text-based operations.
SharpTools is designed to give AI the same insights and tools a human developer relies on, leading to more intelligent and reliable code assistance. It is effectively a simple IDE, made for an AI user.
Due to the comprehensive nature of the suite, it can almost be used completely standalone for editing existing C# solutions. If you use the SSE server and port forward your router, I think it's even possible to have Claude's web chat ui connect to this and have it act as a full coding assistant.
Prompts
The included Identity Prompt is my personal C# coding assistant prompt, and it works well in combination with this suite. You're welcome to use it as is, modify it to match your preferences, or omit it entirely.
