Pyright LSP integrates Microsoft's high-performance Python static type checker into Claude Code. It provides real-time type checking, error detection, and code intelligence for Python projects of any size, including support for both .py and .pyi stub files.

Key features include static type analysis without runtime execution, real-time type error detection and reporting, code diagnostics and quality feedback, and type inference for unannotated code. Pyright is designed for performance and can efficiently analyze large Python codebases.

How to use: Once installed, the language server activates automatically when you open Python files. Claude will use Pyright diagnostics to identify type errors and provide more accurate code suggestions. You can ask Claude things like "check this file for type errors" or "what type issues are in my Python code" to leverage the type checking capabilities.
