fastmcp.utilities.docstring_parsing

Extract descriptions from function docstrings. Uses griffelib to parse Google, NumPy, and Sphinx-style docstrings. The interface is intentionally narrow — a single function returning a ParsedDocstring — so the implementation can be swapped without touching callers.

Functions

​
parse_docstring 

parse_docstring(fn: Callable[..., Any]) -> ParsedDocstring
Parse a function’s docstring into a summary and parameter descriptions. Tries Google, NumPy, and Sphinx parsers in order, using the first one that successfully extracts parameter descriptions. If none do, returns the full docstring as the description with no parameter descriptions.

​
Classes

​
ParsedDocstring

The extracted description and per-parameter descriptions from a docstring.
