PolyMCP turns Python functions into a single Pyodide WASM bundle so agents can call tools directly in the browser or at the edge — neat and practical. It keeps MCP niceties like input validation, error handling, and orchestration inside the bundle and ships runnable demo HTML to prove the flow. Be realistic about Pyodide trade-offs: bundle size and no native-extension support make this best for lightweight, interactive tools and demos rather than heavy backend workloads.
Shuffling metaphor with real math—97.5% Fisher-Yates quality but solves no obvious problem over standard random.
