Needless to mince words, this project has quite a few problems.
Tips
register
毋庸 is decidedly literary — pick it for written or formal speech. It almost always appears in fixed collocations: 毋庸置疑 (beyond doubt), 毋庸讳言 (no need to hide / frankly), 毋庸赘言 (needless to elaborate). In casual speech use 不用 (búyòng) or 不必 (búbì) instead.
grammar
毋 (wú) is a classical negation meaning 'do not' or 'no need to', and 庸 here means 'use / need'. Together: 'no need to [verb]'. The same pattern survives in 无庸 (wúyōng), an alternative spelling with identical meaning.
