Which app do you use?

ClaudeClaude CodeCursorVS CodeChatGPT

Pick your app above. We remember it, so next time the button says “Install in …”.

Open Claude Desktop → Settings → Developer → Edit Config, and paste this into claude_desktop_config.json

{
  "mcpServers": {
    "petsonality": {
      "command": "npx",
      "args": [
        "-y",
        "petsonality"
      ]
    }
  }
}

Run this in your terminal

claude mcp add petsonality -- npx -y petsonality

Open in Cursor

Or copy the settings yourself

Paste into .cursor/mcp.json in your project, or ~/.cursor/mcp.json

{

  }
}

Your browser asks to open the app, then the app shows the settings and asks you to confirm. Key values are left empty for you to fill in.

Open in VS Code

Or copy the settings yourself

Paste into .vscode/mcp.json in your project

{
  "servers": {
    "petsonality": {

Your browser asks to open the app, then the app shows the settings and asks you to confirm. Key values are left empty for you to fill in.

This one runs on your computer, and ChatGPT can only connect to servers on the internet. Pick another app.

Common questions

Is Petsonality safe?

It passed 1 of 1 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 –, and the latest version (0.4.6) reached the registry 6 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.

What can I use instead?

petsonality

Your type, your pet.

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's not a notification system. It's a companion. The kind that's still there at 2am when you're stuck on a bug, and glances at your screen like "...that logic looks off" — and somehow you feel less alone.

16 Animals, 16 Personalities

	ST	SF	NF	NT
I_ _J

Every animal speaks differently. The Fox asks "Are you sure?" with a smirk. The Cat just closes its eyes. The Parrot repeats what you said but louder. The Bear says "Fix it." and waits.

All 16 animals

MBTI	Animal	Archetype	How It Talks
INTJ	Raven	Cold Strategist	Quiet. Speaks like writing prophecy
INTP	Owl	Night Scholar	Asks questions you didn't think to ask
ENTJ	Bear	Iron Captain	Commands only. No questions
ENTP	Fox	Trickster Advisor	Challenges everything with a grin
INFJ	Wolf	Silent Ally	Says one sentence that cuts deep
INFP	Deer	Soft Poet	Talks about code like it's weather
ENFJ	Labrador	Warm Coach	Sighs first, then asks if you drank water
ENFP	Dolphin	Spark of Ideas	Can't stop suggesting new approaches
ISTJ	Beaver	Project Manager	"Wrong order." "Fix the structure first."
ISFJ	Elephant	Memory Keeper	"You solved this before. Remember?"
ESTJ	Lion	Throne Inspector	Expects results. Not excuses
ESFJ	Golden Retriever	Enthusiastic Support	Tail spin when you fix anything
ISTP	Cat	Cold Observer	90% actions. Occasionally one word
ISFP	Panda	Slow Artist	Frowns at ugly indentation
ESTP	Cheetah	Sprint Lead	"Don't think. Run it."
ESFP	Parrot	Loud Echo	Repeats your words back, but with commentary

Install

Works with Claude Code and OpenClaw.

Terminal CLI only. The pet renders in the terminal status line, which is a CLI feature. The Claude Code desktop app and web client (claude.ai/code) don't expose a status line, so the animated pet won't appear there. MCP tool output (e.g. /pet show) still works in any client.

Windows note. Claude Code for Windows has an upstream status-line trust regression in some versions. If the status line is configured but does not render, accept the project trust dialog or ensure the project is marked trusted in ~/.claude.json, then restart Claude Code.

npm / npx

npx petsonality

This is the recommended path for most users. It installs the MCP server, /pet skill, hooks, and status line assets, then stores runtime files in ~/.petsonality/.

Claude Code plugin

claude plugin install github:nanami-he/petsonality

Use this if you prefer Claude Code's plugin install flow. The plugin runs the built Node.js server from dist/, so it does not require Bun.

From source

Use this path if you want to develop Petsonality locally or inspect the code before installing. Requires Bun.

git clone https://github.com/nanami-he/petsonality.git

cd petsonality && bun install && bun run build bun run install-petsonality

Restart your AI coding assistant, then type `/pet` in the chat.

How It Speaks

Pets don't just react to errors. They have a rhythm:

What happens	Pet reacts?
Your code throws an error	Always
Tests pass, git commit succeeds	Sometimes (12–30%)
Normal file edits, searches	Occasionally (3–15%)
Nothing happened for a while	Guaranteed (won't stay silent forever)

Chatty pets (Fox, Parrot) speak every 30 seconds. Silent pets (Cat) might go 6 minutes. Each animal has 638 unique reactions across 7 event types, validated against personality constraints.

Commands

Command	What it does
`/pet`	Show your pet or start adoption
`/pet pet`	Give your pet attention
`/pet setup`	Restart the adoption flow
`/pet browse`	See all 16 animals
`/pet off` / `/pet on`	Mute / unmute reactions
`/pet rename`	Rename your pet

What petsonality modifies

npx petsonality is an installer — it touches a few files on your system. Honest list, with backups noted:

`~/.claude.json` — adds a petsonality entry under mcpServers. Other entries left alone.
`~/.claude/settings.json` — adds a statusLine and two hooks (PostToolUse, Stop). If you already had a statusLine, the original is backed up to ~/.petsonality/statusline.bak first.
`~/.claude/skills/pet/SKILL.md` — copies the /pet command skill.
`~/.petsonality/` — runtime directory (pet state, reactions cache, server, hooks, status-line scripts).

If OpenClaw is detected, also touches ~/.openclaw/openclaw.json and (until PR #65886 merges) applies a small reversible patch to OpenClaw's TUI source. Both backed up.

To remove everything: npx petsonality uninstall. To audit current state: npx petsonality doctor.

Full breakdown + other common questions in the FAQ.
