chibi-mcp
chibi-mcp adds a local desktop pet, chibi, to Claude Code, Codex, and VS Code that turns your machine's own state — CPU, RAM, battery, idle — into a character's mood. Other coding pets animate what your agent is doing; *chibi shows how your machine is doing* — then lets you collect characters and apply free visual layers across a coding session.
It is local-first: no telemetry, localhost WebSocket by default, open-source code, and chibi-mcp --check for install diagnostics.

<p align="center"> <img src="docs/demo.gif?v=1.4.39-chibi" alt="animated chibi-mcp demo showing install commands, local status, and the floating pet window" width="720"> </p>
Public beta — free, local-first, and open source. No paid packs, license keys, or team pricing.
Quick start (30 seconds)
Claude Code (Linux/macOS) — install, then summon the pet:
bash <(curl -fsSL https://raw.githubusercontent.com/soccz/chibi-mcp/main/scripts/install-claude.sh)In Claude Code, type /chibi-mcp:chibi. Confirm the install with:
chibi-mcp --checkUsing Codex, VS Code, Windows, or PyPI instead? Jump to Install.
Why chibi is different
Most desktop pets just animate a character, and agent overlays mirror what your AI is typing. chibi reflects your own machine — CPU, RAM, battery, idle — and your coding-session rhythm, as a collectible character with local ASMR-style sounds and a Korean dessert / artisan-keycap aesthetic.
| chibi | Typical desktop pets (e.g. Shimeji) | Agent-activity overlays | |
|---|---|---|---|
| Mood driven by your machine (CPU/RAM/battery/idle) | ✅ | ❌ | ❌ |
| Reacts to Claude/Codex tool-call rhythm | ✅ | ❌ | ⚠️ partial |
| Collect characters + free option layers | ✅ | ⚠️ skins only | ❌ |
| Local ASMR-style sounds (generated, no download) | ✅ | ❌ | ❌ |
| MCP-native across Claude Code / Codex / VS Code | ✅ | ❌ | ⚠️ varies |
| No telemetry · localhost-only · open source | ✅ | ⚠️ varies | ⚠️ varies |
| One-command install across three clients | ✅ | ❌ | ⚠️ varies |
The trends chibi builds on — slime ASMR, Korean artisan keycaps, chibi style — are cited with sources in SPEC.md.
What You Get
- A local MCP server for Claude Code and Codex.
- A floating desktop pet window for Linux, macOS, and Windows desktop sessions.
- A VS Code sidebar extension packaged as a
.vsix. - 8 starter characters available now — 29 total, more dropping soon — plus 12 free option layers.
- Gacha, inventory, rename, active character, and option selection tools.
- Floating-window controls for inventory, option customization, gacha pulls,
settings, size, connection status, and close actions.
- Mood based on CPU, RAM, battery, and idle time.
- Session cadence: Claude/Codex tool calls move the rhythm meter; every N calls,
chibi plays a small milestone animation.
chibi-say, a tiny CLI for making the pet show speech bubbles from scripts.- Built-in local ASMR-style sounds for squish, milestone events, gacha pulls,
rare pulls, option changes, and speech bubbles.
The base product is free. Monetization is not enabled: no paid packs, no paid random pulls, no Sponsors tiers, no license keys, and no team pricing unless explicitly approved later.
Sounds are also part of the free base product. The app generates short local .wav files in ~/.chibi-mcp/sounds/; no sound assets are downloaded at runtime and no sound gacha is enabled.
What It Does While Running
| Local signal | chibi reaction |
|---|---|
| CPU 80%+ | 헐떡 mood, warmer stage, panting accents |
| Battery under 20% while unplugged | 졸림 mood, slower bob, drowsy marks |
| Recent Claude/Codex tool call | 신남 mood, rhythm progress, optional bubble |
| 30 minutes idle | 시무룩 mood, quieter idle bubble |
| Every N tool calls | slice/milestone animation |
Gacha refill is free and local: the first pull each calendar day is free, then you get +1 ticket per 100 captured tool calls and +1 ticket per 10 rhythm slices. Claude Code plugin hooks record every PostToolUse event; bubbles are still throttled so the pet does not talk on every command.

Requirements
- Python 3.12+
pipx- Claude Code, Codex, or VS Code depending on your client
- A real desktop session for the floating pet window
- Python
tkintersupport for the floating window
On Ubuntu/Debian:
sudo apt-get install -y python3-tkIf you use pyenv Python, install tk-dev first, then rebuild that Python version.
Install
The one-command installers below set up the MCP server and register it with your client. The server is also published on PyPI — pipx install chibi-mcp — for manual or CI setups (see INSTALL.md).
Claude Code
Linux/macOS:
bash <(curl -fsSL https://raw.githubusercontent.com/soccz/chibi-mcp/main/scripts/install-claude.sh)Windows PowerShell:
powershell -NoProfile -ExecutionPolicy Bypass -Command "irm https://raw.githubusercontent.com/soccz/chibi-mcp/main/scripts/install-claude.ps1 | iex"Then in Claude Code:
/chibi-mcp:chibi
/chibi-mcp:chibi 뽑기
/chibi-mcp:chibi 보관함If Claude replies with a login/auth error (/login or a 401), authenticate with /login in Claude Code and retry /chibi-mcp:chibi. To test the pet without Claude, see Verify install; for anything else, see Troubleshooting.
Codex
Linux/macOS:
bash <(curl -fsSL https://raw.githubusercontent.com/soccz/chibi-mcp/main/scripts/install-codex.sh)Windows PowerShell:
powershell -NoProfile -ExecutionPolicy Bypass -Command "irm https://raw.githubusercontent.com/soccz/chibi-mcp/main/scripts/install-codex.ps1 | iex"Then ask Codex:
chibi 보여줘
chibi 뽑기 한 번
chibi 보관함 열어
chibi 꿀 글레이즈 옵션 적용해줘If Codex reports a login/authentication error before it can use the MCP server, run codex login, then retry. chibi-mcp --doctor reports Codex auth and MCP registration separately from the local chibi runtime.
VS Code
Linux/macOS:
bash <(curl -fsSL https://raw.githubusercontent.com/soccz/chibi-mcp/main/scripts/install-vscode.sh)Windows PowerShell:
powershell -NoProfile -ExecutionPolicy Bypass -Command "irm https://raw.githubusercontent.com/soccz/chibi-mcp/main/scripts/install-vscode.ps1 | iex"Manual .vsix install:
code --install-extension chibi-mcp-*.vsixOpen the chibi activity bar view in VS Code after install.
If the activity bar view is missing, run code --list-extensions and confirm soccz.chibi-mcp is listed. chibi-mcp --doctor includes this check when the server CLI is installed.
See INSTALL.md for the full Claude/Codex/VS Code and Linux/macOS/Windows install matrix.
Verify Install
Run either command:
chibi-mcp --check
chibi-mcp --doctor
chibi-checkExpected output includes:
ok: true- package version
- asset directory
- catalog count
- option count
tkinter: trueif the floating window can openclientsfrom--doctor, including Claude auth, Codex auth, MCP registration, and VS Code extension visibilityready: truefrom--doctoronly when the local runtime and every detected client path are ready
If tkinter is false or no display session is available, MCP tools still work, but the floating pet window will return a diagnostic instead of opening. If ok is true but ready is false, chibi itself is installed; follow the printed next_steps for Claude login, Codex login/MCP registration, or VS Code extension visibility.

chibi-say
The Python package also installs chibi-say:
chibi-say "build done"
chibi-say "tests failed"
chibi-say --tool-call "tests green"It sends a local WebSocket message to the running chibi server. Plain chibi-say only shows a bubble; --tool-call also advances rhythm/tickets. If nothing is running, it exits quietly, so it is safe inside scripts.
Examples:
# Git post-commit hook
chibi-say "commit!"
# Makefile
build:
npm run build && chibi-say "build done" || chibi-say "build failed"
# CI/local test wrapper
./run_tests.sh && chibi-say "tests green" || chibi-say "tests red"Claude Code hooks use chibi-say --tool-call on PostToolUse so real tool calls feed mood, rhythm, slices, and tickets. VS Code uses the same local bridge for save/task/debug reactions.

Troubleshooting
See docs/TROUBLESHOOTING.md for the full Claude Code, Codex, VS Code, Linux, macOS, and Windows troubleshooting guide.
chibi-mcp was installed but the command is not found
Run:
pipx ensurepathThen restart your terminal.
Floating window does not open on Linux
Check:
chibi-mcp --check
echo "$DISPLAY"
echo "$WAYLAND_DISPLAY"Test the actual floating window outside Claude/Codex:
chibi-mcp --open
chibi-mcp --open --view-mode debugInstall tkinter on Ubuntu/Debian:
sudo apt-get install -y python3-tkOn macOS Homebrew Python 3.14, if python3 -m tkinter says _tkinter is missing:
brew install [email protected]
pipx uninstall chibi-mcp || true
pipx install "git+https://github.com/soccz/chibi-mcp.git#subdirectory=server"
chibi-mcp --checkThe Claude/Codex one-command installers now attempt this macOS Tk repair automatically and re-run chibi-mcp --check.
Linux installers also attempt Tk repair through common package managers, and Windows PowerShell installers can bootstrap Python/pipx before running the same health check.
VS Code code command is missing
In VS Code, run:
Shell Command: Install 'code' command in PATHThen retry the VS Code installer.
Claude or Codex does not see the server
Register manually:
claude mcp add chibi -- chibi-mcp
codex mcp add chibi -- chibi-mcpIf Claude still prints Unknown command: /chibi or routes /chibi-mcp:chibi to an old command, rerun the Claude installer and restart Claude Code:
bash <(curl -fsSL https://raw.githubusercontent.com/soccz/chibi-mcp/main/scripts/install-claude.sh)If the command replies but no window appears, run chibi-mcp --open in a terminal. It starts a local chibi-mcp --ws-only helper if no WebSocket server is already listening, then prints the direct window result and log paths for ~/.chibi-mcp/window.log and ~/.chibi-mcp/ws.log.
