rubberduck-mcp

Make AI coding feel human.

rubberduck-mcp is an open-source MCP server that transforms your AI assistant into a real-time collaborator. It introduces two lightweight but powerful tools: clarify() and yap().

With clarify(), the AI pauses and asks you when it’s confused - no more mysterious decisions or silent mistakes. With yap(), it shares its thoughts and reasoning as it works - like a helpful, slightly dramatic teammate who always keeps you in the loop.

What it looks like in action:

clarify()
"Should I use Flexbox or Grid to center this form? There are like 7 ways to do it — any preference?"

yap()
"Hmm, this endpoint’s returning 500. Might be the DB... Nope, bcrypt’s acting up again. Let me fix that."

You don’t just see the code - you see what your AI is thinking, struggling with, and trying to solve.

Why it matters:

• AI asks for help instead of silently guessing

• You get real-time insights into its decisions

• Feels more like pair programming, less like prompt engineering

• Fewer mistakes, better communication, smoother flow

Designed for devs:

• One-minute setup

• Works with any MCP-compatible IDE

• Zero lock-in, 100% open source
