SharpToolsMCP

Overview

SharpTools is a robust MCP server that leverages the .NET Compiler Platform (Roslyn) to provide AI agents with advanced capabilities for understanding, analyzing, and modifying C# codebases. It goes beyond simple text-based operations to offer deep static analysis and precise code manipulation, effectively acting as a simple IDE designed specifically for AI users. The server exposes numerous tools via MCP through both Server-Sent Events (SSE) for remote clients and Standard I/O for local process communication.
