roslyn-codelens-mcp

Semantic .NET code analysis, refactoring, and diagnostics

Analyzes .NET codebases semantically to find callers, references, implementations, and type hierarchies without text searching. Surfaces compiler errors, analyzer warnings, dead code, circular dependencies, and async or disposable misuse without running slow builds. Applies safe renames, signature changes, and code fixes across entire solutions with preview diffs. Generates test skeletons and maps stack traces to exact source lines.
