C# diagnostics, navigation and refactoring in Codex, backed by the official Roslyn language server through the Model Context Protocol (MCP).

Find definitions, implementations and references. Preview and apply renames, fixes and refactorings.
The bridge reads saved files and works independently of your editor.
