pi-mcp-adapter vs pi-from-scratch

Q: Which is better, pi-mcp-adapter or pi-from-scratch?

By GitHub stars, pi-mcp-adapter has more community adoption, but the best choice depends on your specific use case.

pi-mcp-adapter: Pi MCP Adapter allows you to use MCP servers with Pi while avoiding token bloat. It lazily connects servers only when needed, caches tool metadata, and provides a single proxy tool to reduce context usage. It supports various lifecycle modes, direct tools, and interactive configuration.; pi-from-scratch: PI from Scratch is a Chinese-language article that rebuilds a minimal version of the pi coding agent, called nano-pi, in TypeScript. The companion site fills in the code alongside the text and offers a step-through trace of the execution flow.
