MCP server for C# code analysis and automated fixing using Roslyn analyzers and code fix providers.
RoselineMCP MCP server exists for a simple reason — assistants are far more useful when they can act on RoselineMCP directly instead of describing what you should do. MCP server for C# code analysis and automated fixing using Roslyn analyzers and code fix providers.
