Most homelab tools show you a graph of right now, and leave "does this matter?" to you. HomeButler remembers what your server looked like last time, decides what is worth saying, and says it — six containers before and six after is not "no change" when one of them is a different container. ## Reading a report ```bash homebutler report homebutler report --keep 7 # retain only the latest 7 snapshots homebutler report --no-save # preview without writing a snapshot ``` `report` gives you a concise butler-style summary of your homelab: current health, warnings, notable changes since the previous snapshot, and suggested next commands. On the first run, HomeButler creates a baseline under `~/.homebutler/reports/snapshots/`; later runs compare against the latest snapshot. Old snapshots are pruned automatically (`--keep 30` by default) so reports do not grow forever. Section rules, labels, and severities are colour-coded in a terminal. Colour is dropped automatically when output is piped, redirected, or run from cron. ### Reading a change Every change line, like those in the card at the top, is three columns: **what kind of change**, **what it happened to**, and **what exactly happened**. The kind is one of eight words, and it is the same word in `--json`, so an agent branches on it without reading prose: | Kind | Means | You would see it after | | --- | --- | --- | | `gone` | it was there last time and is not now | `docker rm`, a service stopping, a port closing | | `new` | it was not there last time and is now | starting anything | | `replaced` | same name, different thing underneath | `docker compose up -d` — the container is recreated, so the name and the count are unchanged | | `image` | same container, different image | pulling a new tag | | `state` | same container, running where it was stopped, or the reverse; or a process that keeps restarting | a crash, a crash loop, or bringing something back up | | `port` | same port, a different process answering on it | one service taking over another's port | | `disk` | a mount moved by more than half a gigabyte | anything that writes | | `skipped` | the comparison could not be made | Docker was down when either snapshot was taken | `replaced` is the one the rest of this exists for. A container recreated under the same name leaves every count identical, which is why a report that compares counts — as this one did before 0.26.0 — answers "no significant changes" while the thing you were running has been swapped out underneath you. `skipped` is the second: homebutler says it could not compare rather than reporting nothing changed. An all-clear it cannot stand behind is worse than no answer. The header names the snapshot being compared against, so "what changed" is never ambiguous about the window it covers. 📖 **[What earns a line, and what is deliberately suppressed →](docs/report.md)** ## See it run <img src="assets/demo.gif" alt="a run through homebutler: report naming what moved since the last snapshot — a container gone, a port answered by something new, one recreated behind the same name — then the same answer as JSON with the kind as a field, then doctor listing what is exposed and what has never been backed up with the command for each, then a backup drill booting the archive in its own container and requiring an HTTP health check, then the same report on a phone, then the settings screen editing notification channels" width="820" /> The whole thing in half a minute · <a href="https://www.youtube.com/watch?v=jwRuFoxNWOY">watch it full size</a> ## Why homebutler? HomeButler helps you answer the boring but painful questions every homelab eventually creates: - What is running on my server right now? - Which container owns this port? - Why did this service restart at 3 AM? - Is my backup actually restorable? - Can I install this self-hosted app without hand-writing another compose file? - Can I let an AI assistant inspect my server without handing it a full SSH shell? No daemon required, no database. Run it from a terminal, cron, a web dashboard you start when you want one, or an AI agent. The design goal is simple: give humans and agents a narrow, structured interface to the server. HomeButler returns readable summaries and JSON instead of asking you to trust a black-box shell session. Self-hosting is not hard because one `docker compose up` is hard. It is hard because the maintenance never ends: ports collide, containers restart silently, backups look fine until restore day, and every server becomes a slightly different snowflake. HomeButler is a small operations toolkit for that messy middle. ### Alongside what you already run Keep Uptime Kuma for *is it up*, Beszel or Netdata for *the graph*, Dozzle for *the logs*. HomeButler answers the question none of them ask: **what is different from last time, and does it matter?** - **No agent on the machines it watches.** The binary is put there once with `homebutler deploy` and runs only when asked, over SSH — no daemon, no open port, nothing listening between runs. - **The judgement is a written rule, not a model.** What earns a line is in [docs/report.md](docs/report.md), and the same input gives the same report — no AI required, no account, no paid tier. - **It checks that a backup comes back.** A backup you have never restored is a folder. `backup drill` boots the archive as a second copy of the app, on a network and port of its own, and requires it to answer an HTTP health check before calling the archive good — then removes everything it made. A failed drill exits non-zero, so `backup drill --all` belongs in the same cron entry as `backup`. [docs/backup.md](docs/backup.md#drill-proving-the-backup-comes-back) has what it does and what it does not prove. ``` 🔐 Integrity: ✅ tar valid (8 files) 🚀 Boot: ✅ container started in 0s 🌐 Health: ✅ HTTP 200 on port 60405 ✅ DRILL PASSED ``` ## Quick Start ```bash # One-line install (auto-detects OS/arch) curl -fsSL https://raw.githubusercontent.com/Higangssh/homebutler/main/install.sh | sh # Or via Homebrew brew install Higangssh/homebutler/homebutler # Or as a container — the hub that reaches your machines over SSH docker run -d --name homebutler -p 8080:8080 -v ~/.config/homebutler:/config -v ~/.ssh:/root/.ssh:ro \ -e HOMEBUTLER_TOKEN="$(openssl rand -hex 16)" ghcr.io/higangssh/homebutler docker exec homebutler printenv HOMEBUTLER_TOKEN # the token, to sign in to the dashboard # Interactive setup — add your servers in seconds homebutler init ``` Or as a container, reaching your machines over SSH — [docs/docker.md](docs/docker.md): `docker run -p 8080:8080 -e HOMEBUTLER_TOKEN=… -v ~/.config/homebutler:/config -v ~/.ssh:/root/.ssh:ro ghcr.io/higangssh/homebutler` Use it right away: ```bash homebutler status # CPU, memory, disk, uptime homebutler docker list # running containers homebutler inventory scan # containers + ports + topology homebutler report # butler-style health report + change summary homebutler install uptime-kuma # deploy a self-hosted app homebutler backup drill uptime-kuma # verify a backup actually restores homebutler watch tui # terminal dashboard homebutler serve # web dashboard at http://localhost:8080 ``` Machine-readable output is available everywhere: ```bash homebutler status --json homebutler inventory scan --json homebutler report --json ``` ## What else it does - **Install apps** — deploy Uptime Kuma, Jellyfin, Pi-hole, Gitea, Portainer, and more with one command - **Map your server** — see containers, exposed ports, system ports, and service topology - **Run a doctor check** — diagnose resource pressure, stopped containers, public ports, backup hygiene, notifications, report baseline readiness, and configured Proxmox endpoint reachability - **Catch crashes** — save logs before/after Docker, systemd, or PM2 restarts and detect flapping loops - **Verify backups** — boot backups in isolated containers before you trust them - **See a Proxmox cluster** — nodes, QEMU and LXC guests, storage, task status, and honest dashboard freshness, with power actions that name their target explicitly - **Use it anywhere** — CLI, JSON, web dashboard, or MCP for AI agents without giving them SSH ## 🩺 Doctor Check ```bash homebutler doctor homebutler doctor --strict # non-zero exit if warnings/failures are found homebutler doctor --json # automation / MCP friendly ``` <img src="assets/doctor-card.svg" alt="homebutler doctor reporting a full disk, a stopped container, and a missing report baseline, each with the command to run next" width="700"> `doctor` is a read-only preflight for the problems homelab users usually discover too late: high disk or memory usage, stopped containers, public bind ports, stale or missing backups, missing notifications, whether `report` has a baseline for change detection, and whether each configured Proxmox endpoint is reachable with the token it has. Every finding names the next command to run, so `--strict` makes it usable from cron or CI — including a Proxmox host that is unreachable or rebooting. Every finding carries a `category`, and `--json` carries the same word, so a caller filters on it without reading the title: | Category | What it is about | | --- | --- | | `system` | CPU, memory, disk | | `docker` | containers that are stopped or unhealthy | | `exposure` | ports listening on every interface | | `backup` | backups missing, stale, never drilled, or growing without a retention limit | | `report` | whether there is a baseline to compare against | | `watch` | targets listed with nothing polling them | | `notifications` | channels configured, or never tested | | `proxmox` | an endpoint that cannot be reached with the token it has | | `config` | the config file itself — permissions, keys homebutler does not know | | `incomplete` | a collector did not answer, so this diagnosis is partial | | `overall` | nothing specific: the all-clear | `incomplete` is the one worth handling. It means the answer you are reading is missing a section, which is different from that section being fine. ### 🗂 Config Validation ```bash homebutler config validate homebutler config validate --strict # exit non-zero on warnings too homebutler config validate --json ``` `config validate` reads your config without starting anything and tells you which file was used, which of the four resolution rules picked it, and what homebutler actually made of each section. It exists because the two ways config goes wrong are both silent: a key homebutler does not recognise is dropped without a word, and a `--config` path that does not exist falls back to built-in defaults rather than failing. ```text Sections ✓ servers 2 servers (homelab, nas) · notify not set ✓ alerts cpu 95% · memory 85% · disk 90% Findings ⚠️ Line 5: field notifiy not found in the homebutler config → Did you mean "notify"? Unrecognised keys are ignored silently. ``` ## Watch and alerts ### 🔄 Process Restart Watch Your container crashed at 3 AM — but **why?** `homebutler watch` catches it the moment it happens, saves the dying logs, figures out the cause, and tells you if it's happening over and over. **Supported backends:** Docker (real-time event stream) · systemd (polling) · PM2 (polling) #### Step 1: Add targets to watch ```bash homebutler watch add nginx # Interactive: choose Docker / systemd / PM2 homebutler watch add --kind docker nginx # or specify directly homebutler watch add --kind systemd nginx.service homebutler watch add --kind pm2 my-api homebutler watch add --kind systemd web --unit nginx.service # listed as web, checked as nginx.service homebutler watch list # See what you're watching ``` #### Step 2: Start monitoring ```bash homebutler watch start # Foreground, Ctrl+C to stop homebutler watch start --interval 10s # Custom poll interval (default 30s) ``` ```bash homebutler watch install # register it with systemd or launchd homebutler watch installed # is it registered? homebutler watch uninstall ``` `watch install` hands the loop to whatever supervises the host — a systemd user unit on Linux, a launchd agent on macOS — so monitoring survives logout and reboot. Both are user-level and neither is a preference: on Linux the watch list lives in your home directory, so a root unit would find an empty list; on macOS Docker Desktop only runs inside a logged-in session, so a LaunchDaemon would poll a daemon that is not there. On Linux a user unit stops at logout unless lingering is on; `watch install` checks, and if it is off tells you to run `loginctl enable-linger $USER` (with sudo only if your system refuses it). `watch start` is the monitoring process. It watches the containers and services on the watch list for restarts, checks CPU, memory and disk against your thresholds, and runs any remediation rules you have configured — one process, one set of notification providers. `alerts --watch` still exists and does the threshold half on its own. Every endpoint under `proxmox:` in your config is polled too: unreachable or ACL-filtered endpoints and any guest listed under that endpoint's `guests:` report one incident when the problem starts and one recovery incident when it clears. A guest not listed there is observational only — `watch start` never alerts on it, deliberately stopped or not. See [Proxmox setup →](docs/proxmox.md#watch-integration) for the `guests:` field. When a crash is detected, you'll see: ``` [03:14:22] INCIDENT: nginx (incident nginx-20260410-031422.581-7a2124) Crash: OOM — process killed by SIGKILL (oom, confidence: high) ⚠ FLAPPING: acute (3 restarts in short window) ``` #### Step 3: Investigate ```bash homebutler watch history # List all incidents homebutler watch show <incident-id> # Full details ``` `watch show` output includes: - **Pre-death logs** — what the process printed right before it died - **Post-restart logs** — what happened after the restart - **Crash analysis** — category (oom / panic / segfault / timeout / dependency / error), reason, confidence level, matched log patterns - **Flapping status** — if the process is stuck in a crash loop #### Crash Analysis Every incident is automatically analyzed using exit codes and log patterns: | Signal | Exit Code | Meaning | |--------|-----------|---------| | SIGKILL | 137 | OOM Killer or forced kill | | SIGSEGV | 139 | Segmentation fault (memory corruption) | | SIGTERM | 143 | Graceful shutdown request | | — | 1 | Application error | | — | 0 | Clean exit (may be intentional restart) | Log patterns like `panic:`, `Out of memory`, `Connection refused`, `FATAL`, and `timeout` are matched automatically to help identify the root cause. #### Flapping Detection Detects when a process is stuck in a restart loop (e.g., crash → restart → crash again): - **Acute** — 3+ restarts within 10 minutes (something is broken right now) - **Chronic** — 5+ restarts within 24 hours (slow recurring issue) Flapping incidents are tagged `[FLAPPING]` in history and highlighted in `watch show`. #### Notifications (optional, off by default) Notifications are disabled by default, which is useful for air-gapped or closed networks where everything runs locally. A minimal example in `~/.config/homebutler/config.yaml`: ```yaml notify: telegram: bot_token: "your-bot-token" chat_id: "your-chat-id" watch: enabled: true notify_on: flapping cooldown: 5m flapping: short_window: 10m short_threshold: 3 long_window: 24h long_threshold: 5 retention: max_incidents: 200 alerts: cpu: 90 memory: 85 disk: 90 rules: - name: cpu-spike metric: cpu threshold: 90 action: notify - name: elsa-monitor-down metric: container kind: systemd # docker (default) | systemd | pm2 watch: [lh-elsa-monitor.service] action: restart ``` ### Restarting things that are not containers `action: restart` restarts Docker containers unless the rule says otherwise. `kind: systemd` or `kind: pm2` points it at a service or a PM2 app instead. The kind is written on the rule rather than looked up from the watch list, so restarting a host service is something you asked for in the config. It also means every rule written before `kind` existed keeps meaning exactly what it meant. Two things worth knowing before using it: **`systemctl restart` needs root or a polkit rule.** Running homebutler unprivileged, a systemd restart will be refused, reported as failed, and warned about when `alerts --watch` starts rather than when the rule first fires. **A target that is flapping is not restarted.** Restarting something already in a restart loop feeds the loop, and most systemd units carry `Restart=always`, so homebutler restarting them fights systemd's own backoff. The thresholds are the `watch.flapping` ones above, and the skip is reported rather than counted as either success or failure. This applies to Docker targets too. Legacy `~/.homebutler/watch/config.json` is still read as a fallback for watch-specific settings, and legacy `alerts.yaml` notify/webhook provider settings are still accepted for older setups. - `watch.enabled: true` — allow watch notifications - `watch.notify_on: flapping` — notify only when repeated restart loops are detected - `watch.notify_on: incident` — notify on every incident - `watch.notify_on: all` — notify on both incidents and flapping - `watch.notify_on: off` — disable watch notifications without removing provider config - `watch.cooldown: 5m` — suppress duplicate notifications for the same event fingerprint during the cooldown window - `watch.flapping` — optional advanced tuning for restart-loop detection - `watch.retention.max_incidents: 200` — how many incidents to keep on disk, newest first. The directory grows fastest exactly when a service is restarting in a loop. Set `-1` to keep everything. Each incident keeps up to 100 captured log lines per side, and at most 64 KB of them. Line counts alone do not bound a file: one stack trace or JSON document on a single line is arbitrarily long, and a container being OOM-killed is exactly the one likely to write one. A log that does not fit keeps its end — the last thing a process said is what explains why it stopped — and says how much was dropped. These settings can also be written under a `watch.notify:` block, which is the canonical form: ```yaml watch: notify: enabled: true notify_on: flapping cooldown: 5m flapping: short_window: 10m ``` Both spellings are read, so either layout works. If a file contains both, the `notify:` block wins and `homebutler config validate` says so. #### Manage targets ```bash homebutler watch remove nginx # Stop watching homebutler watch check # One-shot check (no continuous monitoring) ``` ### Alert Thresholds (Advanced) `alerts` still exists for CPU, memory, and disk threshold checks, but it is an advanced flow and not the recommended first step for new users. ```bash homebutler alerts --watch # default: 30s interval homebutler alerts --watch --interval 10s # check every 10 seconds homebutler alerts history # view alert history homebutler notify test # test your notification channels ``` Default thresholds: CPU 90%, Memory 85%, Disk 90%. Start with `watch`, then add `alerts` only if you specifically want threshold-based checks. ## Backup & Restore One-command Docker backup — volumes, compose files, and env variables. ```bash homebutler backup # backup everything homebutler backup --service jellyfin # specific service homebutler backup --to /mnt/nas/backups/ # custom destination homebutler backup list # list backups homebutler restore ./backup.tar.gz # restore ``` > ⚠️ Database services should be paused before backup for data consistency. 📖 **[Full backup documentation →](docs/backup.md)** — how it works, archive structure, security notes. ### 🔍 Backup Drill **"Having a backup" and "being able to restore" are different things.** Backup Drill boots your backup in an isolated Docker environment and verifies the app actually responds — like a fire drill for your data. A failed drill exits non-zero. ```bash homebutler backup drill uptime-kuma # verify one app homebutler backup drill --all # verify all apps homebutler backup drill --json # machine-readable output homebutler backup drill --archive ./file # use a specific backup ``` Full walkthrough, including what a passing drill does *not* prove: [docs/backup.md](docs/backup.md#drill-proving-the-backup-comes-back). **What happens:** 1. Finds the latest backup archive 2. Verifies archive integrity (`tar` validation) 3. Creates an isolated Docker network + random port 4. Boots the app from backup data 5. Runs an HTTP health check 6. Reports pass/fail and cleans up everything ``` 🔍 Backup Drill — uptime-kuma 📦 Backup: ~/.homebutler/backups/backup_2026-04-04_1711.tar.gz 📏 Size: 18.6 MB 🔐 Integrity: ✅ tar valid (8 files) 🚀 Boot: ✅ container started in 0s 🌐 Health: ✅ HTTP 200 on port 58574 ⏱️ Total: 2s ✅ DRILL PASSED ``` **Zero risk** — runs in a completely isolated environment. Your running services are never touched. Supports health checks for: `nginx-proxy-manager`, `vaultwarden`, `uptime-kuma`, `pi-hole`, `gitea`, `jellyfin`, `plex`, `portainer`, `homepage`, `adguard-home`. ## App Install ``` $ homebutler install list 📦 Available apps (15): uptime-kuma A self-hosted monitoring tool vaultwarden Lightweight Bitwarden-compatible password manager jellyfin Free software media system for streaming movies, TV, and music pi-hole Network-wide ad blocking via DNS filtering … ``` > **`homebutler install uptime-kuma`** — Deploy self-hosted apps in seconds.

Docker-published ports are connected back to the container that owns them, so local forwarding details like Colima/Lima stay understandable. ```text 🏠 Home Network Server homelab (192.168.1.10) Summary ✅ 1 running · ⚪ 1 stopped · 🌍 2 public ports · 🔒 4 local ports 📦 Containers (2) ├─ ⚪ vaultwarden · not started │ └─ image vaultwarden/server:latest └─ ✅ api-server · running ├─ image my-api:latest └─ exposes :8080 → 8080/tcp 🌐 App Ports (1) └─ 🌍 :8080/tcp · api-server ``` To answer "what is reachable from outside my machine/network?" without reading the whole tree, filter the scan to exposed ports only: ```bash homebutler inventory scan --filter exposed ``` ```text 🏠 Home Network Server homelab 🌐 Exposed Ports ├─ :8080/tcp · api-server └─ :8443/tcp · dashboard ``` Only ports listening on all interfaces (`0.0.0.0`, `::`, `*`) are shown. Anything bound to a specific address is hidden, including loopback and LAN addresses. Unsupported filter values return an error, as does combining `--filter` with `--json`; the default `inventory scan` output is unchanged. Use Mermaid export when you want a diagram for GitHub, Obsidian, docs, or an AI assistant: ```mermaid graph TD home["🏠 Home Network"] --> homelab["🖥 homelab 192.168.1.10"] homelab --> c1["📦 api-server running"] homelab --> p1["🌍 :8080/tcp api-server"] c1 -. exposes .-> p1 ``` ## 🧊 Proxmox VE ```bash homebutler proxmox status homebutler proxmox guests --status running homebutler proxmox guest shutdown --node pve1 --type lxc --vmid 105 --confirm homebutler proxmox task UPID:pve1:... --node pve1 ``` A Proxmox endpoint is its own kind of target, configured under `proxmox:` with an API token rather than SSH, so it does not join the `--server` or `--all` fan-out. TLS verification stays on: trust comes from a pinned SHA-256 fingerprint, then a CA file, and only then an explicit `insecure` fallback. Reads are plain. Power actions are not: every one of them takes an explicit endpoint, node, guest type and VMID, and refuses to run without `--confirm`, which is checked before any credential is read. They also need their own `action_token_id` (plus `action_token` or `action_token_file`) configured on the endpoint — the read token alone will not start, reboot, or shut down a guest; see [Proxmox setup →](docs/proxmox.md) for creating that second token. `shutdown` asks the guest to shut down cleanly — it is not Proxmox's hard `stop`, which cuts power and can leave a filesystem behind it. A successful action reports the task it submitted, not that the guest finished; `proxmox task` answers that separately. `proxmox script` prints the install command for a Community Script pinned to one commit, along with a warning that the script is not reviewed by homebutler and runs as root. It never fetches or runs it — see [#62](https://github.com/Higangssh/homebutler/issues/62) for why that line is where it is. 📖 **[Proxmox setup, tokens, and TLS →](docs/proxmox.md)** ## Installation ### Homebrew (Recommended) ```bash brew install Higangssh/homebutler/homebutler ``` Automatically installs to PATH. Works on macOS and Linux. ### One-line Install ```bash curl -fsSL https://raw.githubusercontent.com/Higangssh/homebutler/main/install.sh | sh ``` Auto-detects OS/architecture, downloads the latest release, and installs to PATH. macOS and Linux only; on Windows, use the zip below. ### Windows Download `homebutler_<version>_windows_amd64.zip` (or `_windows_arm64.zip`) from the [latest release](https://github.com/Higangssh/homebutler/releases/latest), extract `homebutler.exe`, and put it in a folder on your `PATH`. `homebutler upgrade` replaces it with the next release's. The npm package needs Windows 10 version 1803 or later, whose `tar.exe` it extracts the zip with. On Windows, `status` and what is built on it read this machine, and `ports` and `processes` say they are not supported. Servers in your config are reached over SSH as from any other machine, with keys read from `C:\Users\<you>\.ssh` ([configuration](docs/configuration.md)). ### npm (MCP server) ```bash npm install -g homebutler ``` Downloads the Go binary automatically. This package publishes one command, `homebutler-mcp`, and it starts the MCP server — `npx -y homebutler@latest` launches that, not the CLI. For the command line, use one of the other installs above. ### Claude Desktop extension (MCP server) Download `homebutler_<version>_darwin_arm64.mcpb` (Apple silicon), `homebutler_<version>_darwin_amd64.mcpb` (Intel Mac), `homebutler_<version>_windows_amd64.mcpb` (Windows) or `homebutler_<version>_windows_arm64.mcpb` (Windows on Arm) from the [latest release](https://github.com/Higangssh/homebutler/releases/latest) and open it, or drag it onto Claude Desktop's Settings → Extensions. The binary is inside, so nothing else needs installing. It starts read-only; see [the MCP docs](docs/mcp-server.md#claude-desktop-extension) to allow more. ### Go Install ```bash go install github.com/Higangssh/homebutler@latest ``` ### Build from Source ```bash git clone https://github.com/Higangssh/homebutler.git cd homebutler make build-all ``` `make build-all` compiles the web dashboard into the binary and needs Node installed. `make build` skips it — the CLI is complete either way, and `homebutler serve` then says the dashboard is missing and names the two ways to get it. ### Uninstall ```bash rm $(which homebutler) # Remove binary rm -rf

Docker, no extra dependencies. ```bash homebutler serve # http://localhost:8080 homebutler serve --port 3000 # custom port homebutler serve --demo # demo mode with sample data homebutler serve install # hand it to launchd or systemd, so it survives logout homebutler serve uninstall # and take it back ``` The installed unit records the address and never the token — that comes from `web.token` in the config file, because `--token` is visible in `ps` to every user on the machine. In a container, set `HOMEBUTLER_TOKEN` instead; it is used when neither of the others is set, and never written to the config. 📖 **[Web dashboard details →](docs/web-dashboard.md)** </details> ## Configuration ```bash homebutler init # interactive setup wizard ``` 📖 **[What `report` compares →](docs/report.md)** — what earns a line, what is deliberately suppressed, and why. 📖 **[Configuration details →](docs/configuration.md)** — config file locations, watch/notify options, and advanced alert thresholds. ## Multi-server Manage multiple servers from a single machine over SSH. ```bash homebutler status --server rpi # query specific server homebutler status --all # query all in parallel homebutler deploy --server rpi # install on remote server homebutler upgrade # upgrade all servers ``` 📖 **[Multi-server setup →](docs/multi-server.md)** — SSH auth, config examples, deploy & upgrade. ## MCP Server Built-in [MCP](https://modelcontextprotocol.io/) server — an agent gets the same report as typed JSON, kind, target and detail rather than a sentence to parse, and every tool is classed read, write or destructive. > **Use natural language when you want automation.** MCP clients can call homebutler tools to check server status, list Docker containers, inspect ports, or run operational workflows. ```json { "mcpServers": { "homebutler": { "command": "npx", "args": ["-y", "homebutler@latest"] } } } ``` Works with Claude Desktop, ChatGPT, Cursor, Windsurf, and any MCP client. To let an agent look without being able to change anything, add `"--max-risk", "read"` to `args`. Tools that change something are not offered and are refused if called by name, and `report` runs without saving a snapshot. Read mode stops changes, not reading: logs, container details and everything else a read returns are still visible. [What read mode covers →](docs/mcp-server.md#read-only-mode) 📖 **[MCP server setup →](docs/mcp-server.md)** — supported clients, available tools, agent skills. ## Architecture > **The butler watches, decides what is worth saying, and says it — to you or to an agent.** > > Something changes → `report` names it and ranks it → a notification, the dashboard, or an MCP call > carries the same answer. ``` ┌─────────┐ ┌─────────┐ ┌─────────┐ │ CLI │ │ MCP │ │ Web │ │ stdout │ │ stdio │ │ :8080 │ └────┬────┘ └────┬────┘ └────┬────┘ └────────────┼────────────┘ ▼ internal/* system · docker · ports · network wake · alerts · remote (SSH) ``` **Three interfaces, one core:** | Interface | Transport | Use case | |-----------|-----------|----------| | **CLI** | Shell stdout/stderr | Terminal, scripts, AI agents via `exec` | | **MCP** | JSON-RPC over stdio | Claude Desktop, ChatGPT, Cursor, any MCP client | | **Web** | HTTP (`go:embed`) | Browser dashboard, on-demand with `homebutler serve` | All three call the same `internal/` packages — no code duplication. An agent reads the same report a person does, and gets the parts it has to branch on rather than a screen it has to interpret: ```python report = json.loads(subprocess.run( ["homebutler", "report", "--json"], capture_output=True, text=True).stdout) for change in report["notable_changes"]: if change["kind"] == "replaced": # the container came back as something else redeploy(change["target"]) else: log(change["text"]) # "port: :8080/tcp — nginx → caddy" ``` Every line carries `text` as well, so a caller that only wants to print it does not have to put the sentence back together. A run that found nothing returns `"notable_changes": []`, so the loop above does nothing on a quiet day. Nothing above this is homebutler's business: an MCP client, a chat bot, a cron line or a person at a terminal all reach the same answer. **No ports opened by default.** CLI and MCP use stdin/stdout only. The web dashboard is opt-in (`homebutler serve`, binds `127.0.0.1`). ## Contributing Contributions welcome! Please open an issue first to discuss what you'd like to change. [CONTRIBUTING.md](CONTRIBUTING.md) covers what homebutler accepts and what a new target has to prove. ## Security Found a vulnerability? Report it privately through [the Security tab](https://github.com/Higangssh/homebutler/security/advisories/new) rather than a public issue. [SECURITY.md](SECURITY.md) covers what is in scope and what to expect. ## License [MIT](LICENSE)

homebutler

Tells an agent what changed on a server since it last looked - plus status, Docker, backups, Proxmox. Every tool is classed read, write or destructive, so an agent can tell a look from a change before it makes the call.
