ILSpy-Mcp vs roslyn-codelens-mcp

ILSpy-Mcp: ILSpy MCP Server is a .NET 9-based Model Context Protocol (MCP) server that provides AI assistants with in-memory .NET assembly decompilation and structural analysis capabilities. It acts as a bridge, enabling LLMs to inspect, decompile, and analyze compiled .NET code directly via natural language.; roslyn-codelens-mcp: Roslyn CodeLens MCP is a server that provides AI agents with deep semantic understanding and powerful analytical capabilities for .NET codebases. It offers a rich set of tools for code inspection, refactoring, diagnostics, and quality analysis, enabling advanced automated code manipulation and insights.
