Vibe Check MCP server

Vibe Check is a small helper that gives your AI a second opinion before it acts. When your AI is about to do something big or risky, it can ask Vibe Check to look over the plan first. It is handy for anyone who uses an AI assistant for real work and wants fewer wrong turns.

What this MCP server does

You ask your AI to do something, like plan a project or change a file. Before it charges ahead, your AI sends its goal and plan to Vibe Check. Vibe Check passes that to a second AI model, which reads it and gives back a short review. The review points out shaky assumptions, missing steps, or signs the plan is getting too complicated. Your AI then uses that feedback to adjust what it does next.

What you can do with it

• Get a second opinion on a plan before your AI starts working
• Catch overcomplicated solutions before they get built
• Pause your AI before it takes an action that is hard to undo
• Keep a short memory of earlier advice within one session
• Set simple rules for a session, like no external calls or no secrets on disk
• Log mistakes and fixes so future checks can learn from them

Try asking your AI

• “Before you rewrite the whole report generator, run a vibe check on your plan.”
• “Vibe check this: I am going to delete all old draft files and start fresh.”
• “Ask the mentor if my approach to this spreadsheet cleanup makes sense.”
• “Do a vibe check on my plan to restructure the team folder.”

What it gives back to you

You get a short written review in the chat, not a file. It usually lists concerns, questions, and a suggestion to simplify or slow down. Sometimes it just says the plan looks fine. If you use a session id, it also mentions advice it gave earlier in the same session.

Before you start

Who it's for

People who use an AI assistant for everyday work and want it to slow down and double-check before it does something big.
