About Code Explainer MCP
Analysis runs entirely inside the Worker using regex and pattern matching — there are no LLM calls and no external runtime dependencies. All logic lives in a single file, src/index.ts.
Features
Architecture diagram: Generates an ASCII diagram showing classes (with inheritance), standalone functions, call relationships, and imported dependencies.
Core-functionality analysis: Infers the primary and secondary purpose of the code (network, UI, data processing, database, authentication, testing, algorithm, file system) from weighted pattern…
Component breakdown: Lists the main classes and functions, each with a short generated description.
Multi-language support: Tailored class/function/import patterns for JavaScript, TypeScript, Python, Java, and C#, with a generic fallback for other languages.
Documentation extraction: Reuses existing JSDoc, Python docstrings, and line comments when describing a component.
Bearer-token auth: The POST endpoint is protected by a shared secret.
