Mcp Pyright

daedalus/mcp-pyright

Wraps the Pyright language server to give Claude type checking and code intelligence for Python. You get seven tools: check_types for catching type errors, get_hover for inspecting types at a cursor position, get_completions for autocomplete suggestions, get_definition to jump to where something is defined, find_references to see all uses of a variable or function, get_document_symbols to extract classes and functions from a file, and format_code for cleaning up formatting. Useful when you need Claude to reason about Python code structure, verify type correctness, or provide intelligent suggestions without running the code itself.
