A Chengyu is a traditional Chinese idiom consisting of exactly four characters, often carrying deep historical or poetic meaning.

How do I check if an idiom follows classical poetic meter?

You can use the `check_poetic_meter` tool by providing the hyphenated tone sequence of the idiom.

What does phonetic clashing mean?

Phonetic clashing occurs when a sequence of tones lacks melodic variation, such as four consecutive 4th tones, which disrupts the classical rhythm.

This MCP server provides tools to analyze the structural integrity of Chinese four-character idioms (Chengyu). It uses phonetic tone sequences to validate length, detect phonetic clashing, and check if the idiom adheres to classical poetic rhythms like Ping-Ping-Ze-Ze. You can also evaluate the semantic density to see how much narrative information is contained within the characters. Use validate_chengyu_structure for basic checks, check_poetic_meter for rhythmic analysis, and evaluate_semantic_density for narrative richness.
