# py2mcp.base

Private helpers shared by the builders in [`py2mcp.main`](py2mcp.main.html.md#module-py2mcp.main).

Argument normalization (`funcs` and `middleware` accept one object or an
iterable) and the wrapper that applies an `input_trans` to a tool’s keyword
arguments before the function runs. Nothing here is part of the public API.
