Koskamo

Roslyn Workbench MCP

A local MCP server that brings Visual Studio-style C# fixes, refactorings, and semantic navigation to AI coding agents. It leverages the .NET Compiler Platform (Roslyn) to discover Code Actions, inspect diagnostics, and manage source changes through reviewable transactions with rollback and conflict detection. The server runs locally over stdio, ensuring deliberate source changes only after explicit transaction commits.
