Common questions
Is MCP Vibe Checker safe?
It passed 1 of 2 applicable basic checks. We have not read the code. Before adding a key or token, see what access the server asks for and use a key with only the permissions you need.
What keys or codes does it need?
The registry does not list a required key, though some servers ask you to sign in on first use.
Does it run on my computer or in the cloud?
It runs on your computer. Your AI app starts it when needed, and data does not pass through the maker’s servers (unless it calls an online service itself).
Is it still maintained?
The GitHub repo last changed 7 months ago, and the latest version (0.1.1) reached the registry 7 months ago.
Which apps can use it?
Apps that support MCP, such as Claude Desktop, Claude Code, Cursor and VS Code. You also need Node.js on your computer.

mcp-vibe-check
Your code has energy. Time to find out what kind.
An MCP server that gives your code a vibe check — assigning personality types to functions, rating variable name energy, and suggesting more aesthetic alternatives. Because userData was never the right name. It should be soulContainer.
What It Does
- Personality types for functions — Is
handleSubmita main character, or does it have NPC behavior? Find out. - Variable energy ratings —
xgets "cryptic oracle energy (3/10)".MAXIMUM_RETRY_COUNTgets "dramatic monologue energy (9/10)". They earned it. - Aesthetic name suggestions —
isValid→vibesPassing.error→chaosEvent. You're welcome. - Overall vibe score — A completely arbitrary number between 1 and 10 that means nothing and everything.
- Code aesthetic assessment — Qualitative vibes. Unscientific. Occasionally accurate.
Example
Input:
function handleSubmit(userData, isValid) {
const result = userData.name; return result; }
Output:
{
"overallVibe": "cozy cottage-core with hints of cyberpunk", "vibeScore": 6.8, "functions": [ { "name": "handleSubmit", "personality": "main character energy", "assessment": "This function carries the entire plot" } ], "variables": [ { "name": "userData", "energy": 7, "assessment": "classic protagonist (7/10) — reliable, not flashy", "suggestion": "soulContainer" }, { "name": "isValid", "energy": 7, "assessment": "classic protagonist (7/10) — reliable, not flashy", "suggestion": "vibesPassing" }, { "name": "result", "energy": 5, "assessment": "functional but uninspired (5/10) — exists, which is something", "suggestion": "manifestation" } ], "codeAesthetic": "Your code reads like a mystery novel — lots of setup, unclear payoff", "recommendation": "Consider adding more comments for dramatic tension" }
Install
npx mcp-vibe-check
Configure in Claude Code
Add to your .mcp.json:
{
"mcpServers": { "vibe-check": { "command": "npx", "args": ["-y", "mcp-vibe-check"] } } }
Then ask Claude: "What vibes does this codebase give off?"
Personality Types
Your functions can be:
| Type | Meaning |
|---|---|
| main character energy | Carries the entire plot |
| side quest vibes | Important but easily forgotten |
| NPC behavior | Does its job without complaint |
| protagonist arc | Started simple, evolved into something bigger |
| villain origin story | Nobody asked for this complexity |
| comic relief | Technically unnecessary, yet essential |
| mentor energy | Older, wiser, called at critical moments |
| chosen one potential | Untested but destined for greatness |
FAQ
Is this useful for code review? No. That's the point.
Will this improve my code quality? Statistically unlikely. Spiritually, possibly.
Why does `console.log` hurt my vibe score? Because it's not aesthetic. Use a proper logger. Your stdout deserves better.
My function got "NPC behavior". Should I be offended? Only if your function has feelings. Which, based on this tool, it might.
*"Not all code reviews need to be actionable. Some just need to be vibes."*
