Summary
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.
Keeps your Mac awake while Claude Code, Codex or Cursor works. Lets it sleep when they are done.

The MCP server can be used with any MCP-compatible client. It exposes the following tools:
Type Checking
from mcp_pyright import mcp
# Run type checking
result = check_types(code="x: int = 'hello'")
Get Hover Information
# Get type information at position
result = get_hover(code="x: int = 1", position=0)
Get Completions
# Get code completions
result = get_completions(code="prin", position=4)
Get Definition
# Find definition location
result = get_definition(code="def foo(): pass\nfoo()", position=15)
Find References
# Find all references
result = find_references(code="x = 1\nx", position=5)
Get Document Symbols
# Get all symbols in document
result = get_document_symbols(code="class Foo: pass\ndef bar(): pass")
Format Code
# Format Python code
result = format_code(code="x=1\ny=2")
