Petsonality MCP Server

A tiny ASCII pet that lives in the corner of your terminal while you code. It watches what you do, reacts to your errors, celebrates when tests pass, and speaks with a personality shaped by MBTI - all in 5 lines of art. It runs locally over stdio via the published package.

People connecting this server to Claude, Cursor, VS Code, or another MCP client. The project is written in TypeScript.
