That's it! The server will respond to your query, and you can continue using it as needed.
Here is a step-by-step guide with screenshots.
SysControl
An AI agent for your Mac or Windows 11 PC that answers questions about your system — and can extend itself with new tools on the fly.
116 built-in tools covering CPU, RAM, GPU, disk, network, processes, iMessage, email, clipboard, browser, weather, reminders, Docker, Time Machine, Wi-Fi, calendar, contacts, Notes, Homebrew, media control, file management, Spotlight search, spreadsheets, Word documents, PDFs, image generation, deep web research, sub-agent orchestration, code editing, git integration, and more. Each platform receives only the tools it can execute; the agent picks the right ones automatically, runs them in parallel, and answers in plain English.
Three ways to run it — pick whichever fits your workflow:
How | Best for | |
App (macOS) | One-click native macOS (SwiftUI) experience — no setup required | |
App (Windows) | Native Windows 11 desktop app (Flet) — unzip and run | |
CLI |
| Terminal-first workflow, scripting, SSH sessions (macOS · Windows · Linux) |
Claude Desktop | MCP server | Using SysControl tools inside Claude Desktop |
All interfaces share the same agent, tools, and providers — they're interchangeable.
App (macOS)
A native SwiftUI app with streaming chat, Markdown rendering, chat history sidebar, and auto-save — no Python, no terminal, no dependencies to install. Just download, open, and configure your provider in Settings.
Download
Option A — Pre-built DMG (no Xcode required):
Download the latest SysControl.dmg from GitHub Releases, drag to Applications, then bypass Gatekeeper on first launch (the app is ad-hoc signed, not notarized):
xattr -r -d com.apple.quarantine /Applications/SysControl.appOr right-click the app → Open → Open the first time.
Option B — Install from source (compiles locally, bypasses Gatekeeper automatically):
/bin/bash -c "$(curl -fsSL https://raw.githubusercontent.com/ks6573/SysControl/master/swift/install.sh)"To update later: use Check for Updates in the app (⇧⌘U), or run syscontrol-update from Terminal.
To uninstall: re-run with --uninstall.
Option C — Build manually:
git clone https://github.com/ks6573/SysControl.git
cd SysControl/swift
./build.sh release
open .build/SysControl.appRequires: macOS 14 (Sonoma) or later. Options B and C also require Xcode Command Line Tools (
xcode-select --install).
Features
Streaming responses — tokens appear as they arrive with live Markdown rendering
Auto-save — every conversation is saved automatically with an LLM-generated title
Chat history sidebar — browse and delete past chats
Settings — switch between local (Ollama) and cloud providers in-app
In-app updates — check for new versions from the menu bar (⇧⌘U) or Settings; DMG users get a one-click download, source-install users update automatically
No setup — everything is configured through the app itself
First Launch
On first launch an onboarding sheet appears automatically:
Choose Local (Ollama) — requires Ollama running locally, no API key needed
Or choose Cloud — enter your API key
Click Done and start chatting
To change providers later, open Settings (⌘,).
Chat history is saved as Markdown in
~/.syscontrol/chat_history/— view, edit, or delete freely.

App (Windows)
A native Windows 11 desktop app (built with Flet) with streaming chat, Markdown rendering, expandable tool-call cards, inline charts, a session sidebar, and in-app settings. It runs the same Python agent backend as the macOS app and CLI, bundled into a standalone .exe — no separate Python install to manage.
Download
Download the latest
SysControl-windows-x64.zipfrom GitHub ReleasesUnzip it anywhere (e.g.
%LOCALAPPDATA%\Programs\SysControl)Run
SysControl.exe
First launch: the build is not code-signed, so Windows SmartScreen may warn you. Click More info → Run anyway.
Requires: Windows 11 (x64). For local models, install Ollama for Windows and pull a model (
ollama pull qwen3:30b); for cloud, enter your Ollama Cloud API key during onboarding.
Build from source
git clone https://github.com/ks6573/SysControl.git
cd SysControl
uv sync --extra gui --extra build
uv run pyinstaller SysControl.spec # -> dist\SysControl\SysControl.exeOr run it directly without bundling: uv run syscontrol-gui.
Platform notes
The Windows app exposes the same agent and tools as macOS. System tools — CPU, RAM, GPU, disk, network, processes, battery, files, clipboard, screenshots, volume, Wi-Fi, system logs (Event Log), shell (PowerShell/cmd), web research, charts, spreadsheets/Word/PDF, sub-agents — work natively. macOS-only integrations (iMessage, Apple Mail, Calendar/Contacts, Notes, Time Machine, Homebrew) report that they're unavailable on Windows rather than failing.
CLI
A terminal agent that runs the same backend as the app. Two install paths:
Option A — One-line install (recommended):
/bin/bash -c "$(curl -fsSL https://raw.githubusercontent.com/ks6573/SysControl/master/install-cli.sh)"Installs uv if missing, then runs uv tool install against the GitHub repo, exposing syscontrol and syscontrol-server on your PATH in an isolated venv. No clone required.
To update later: run syscontrol --update (or /update inside the REPL); the standalone syscontrol-cli-update script is also still installed.
To uninstall: re-run with -- --uninstall.
Option B — From a clone (for development):
git clone https://github.com/ks6573/SysControl.git
cd SysControl
curl -LsSf https://astral.sh/uv/install.sh | sh # if uv not installed
uv sync
uv run agent.pyRequirements
macOS, Windows 11, or Linux
Python 3.11+ (uv will fetch one if your system Python is older)
Ollama for local mode, or an Ollama Cloud API key for cloud mode
CLI Flags
syscontrol # interactive
syscontrol --provider local --model qwen3:30b # local, skip prompt
syscontrol --provider cloud --api-key sk-... # cloud, skip prompt (key is remembered)
syscontrol --provider cloud --no-save-key # cloud, prompt every time
syscontrol --provider custom --base-url https://example.com/v1 --model my-model --api-key sk-...
syscontrol --continue # resume the most recent session
syscontrol --resume # pick a previous session from a list
syscontrol --coding --approval normal # coding agent, ask before edits/shell
syscontrol --coding --approval plan # read-only planning mode
syscontrol --coding --approval auto # auto-accept coding edits/shellCloned (Option B) users can substitute
uv run agent.pyforsyscontrolin any of the commands below.
The first time you enter your Ollama Cloud API key (via --api-key or the prompt), it's saved to ~/.syscontrol/cli_credentials.json (0600) so you won't be asked again. Use --no-save-key to opt out, or /logout from the REPL to forget it.
Coding Mode
The CLI can run as a coding agent with a narrowed code tool set: file search/read/edit, git status/diff, and shell commands. Approval modes:
Mode | Behavior |
| Read-only. The agent can inspect and produce an implementation plan, but edits and shell commands are blocked. |
| Reads are automatic; file writes and shell commands ask for approval in the terminal. |
| "Just do it" mode. Auto-accepts coding edits and shell commands for the session. |
Press Shift+Tab to toggle between system monitor mode and coding mode. Inside coding mode,
use /approval plan, /approval normal, or /approval auto to switch policies. The old
standard and nuke names still work as aliases.
Slash Commands & Keyboard Shortcuts
The interactive CLI feels like Codex / Claude Code: type / to pop a completion menu, @ to inline a file from the cwd, ! to run a one-off shell command, and the bottom toolbar shows the active model, provider, approval mode, and message count at all times.
Command | Description |
| Show all commands and keyboard shortcuts |
| Clear the screen |
| Clear conversation history (keeps system prompt) |
| List available tools, optionally filtered by substring |
| Show the active model and provider |
| Toggle system/coding mode or enter a coding sub-mode |
| Run a detected test command, or a provided command, in coding mode |
| Run a detected lint/typecheck command, or a provided command, in coding mode |
| Append a timestamped note to |
| Dump the full output of the most recent tool call |
| List recently saved CLI sessions |
| Generate a |
| Summarize the conversation; |
| Switch coding-mode approval policy |
| Check for and install the latest SysControl release |
| Forget the saved Ollama Cloud API key |
| Quit the session |
Key | Action |
| Submit a single-line buffer; insert a newline once the buffer is multi-line |
| Submit any non-empty buffer; exit on an empty buffer |
| Cancel the in-flight LLM/tool stream (press again within 1s to exit cleanly) |
| History navigation |
| Reverse history search |
| Complete the current slash command, |
| Toggle system/coding mode |
| Clear the screen |
| Always insert a newline (alternative to letting Enter add one in multi-line mode) |
Type @<partial> to pop a file picker scoped to the current directory (uses git ls-files when available; falls back to a recursive walk). Selected paths stay literal in the buffer and are inlined at submit time as fenced code blocks (capped at 64 KB per file).
Type !<command> to run a shell command directly — output prints inline and the LLM is bypassed. Requires allow_shell=true in ~/.syscontrol/config.json.
History is persisted to ~/.syscontrol/cli_history. Conversations auto-save to ~/.syscontrol/cli_sessions/; resume the most recent with syscontrol --continue or pick from a list with syscontrol --resume.
Local Mode (Ollama)
ollama pull qwen3:30b # recommended
ollama serve
syscontrol --provider localTool-calling capable models:
Model | Notes |
| Default. Best tool use and reasoning |
| Faster, lower memory — includes thinking mode |
| Lightweight alternative |
| Battle-tested fallback |
Models without native tool-calling (e.g.
gemma3) will error.
Cloud Mode (Ollama Cloud)
syscontrol --provider cloud
# Enter your key when prompted — not echoed or stored in shell historyGet a key at ollama.com/settings/keys. Default cloud model: gpt-oss:120b.
Any service that implements the OpenAI-compatible chat-completions and tool-calling APIs can be
used with --provider custom, --base-url, --model, and --api-key. Custom-provider keys are
used for the current session and are not written to the Ollama credential entry.
Ending a Session
Say any natural goodbye (bye, exit, quit, done, farewell, cya, goodnight, …) or press Ctrl-C. The agent will offer to save your session before exiting.
Session Memory
On exit you are prompted to save a short note about the session. Notes are appended to SysControl_Memory.md with a timestamp. On next startup, if the file exists its contents are injected into the system prompt so the agent has context from prior sessions. The file is append-only and plain text — edit or delete entries freely.
The agent can also save and recall memory mid-session via the read_memory and append_memory_note tools — no need to wait for exit.
Privacy: SysControl stores only what you explicitly save. Ollama processes queries locally by default.
Permissions & Security
Sensitive tools are disabled by default. Enable them in ~/.syscontrol/config.json:
{
"allow_shell": true,
"allow_messaging": true,
"allow_message_history": true,
"allow_screenshot": true,
"allow_file_read": true,
"allow_file_write": true,
"allow_calendar": true,
"allow_contacts": true,
"allow_accessibility": true,
"allow_tool_creation": true,
"allow_deep_research": true,
"allow_email": true,
"allow_notes": true,
"allow_brew": true,
"allow_agents": true,
"allow_automations": true,
"allow_connectors": true
}Each disabled tool returns an error with the exact flag needed to enable it.
Claude Desktop Setup
1. Add the MCP server to your config
Platform | Config path |
macOS |
|
Windows |
|
{
"mcpServers": {
"system-monitor": {
"command": "/path/to/uv",
"args": ["run", "/absolute/path/to/SysControl/mcp/server.py"],
"env": {}
}
}
}Use which uv to get the uv path.
2. Set the system prompt — create a Claude Desktop Project and paste the contents of mcp/prompt.json into the Project Instructions field.
3. Restart Claude Desktop — system-monitor will appear in the MCP servers list.
Self-Extension
When you ask for something no tool covers, the agent offers to build it:
You: What song is playing in Spotify right now?
Agent: I don't have a tool for that. Want me to create one? (yes/no)
You: yes
Agent: ✓ Tool `get_spotify_track` installed. Restart and ask again.The agent writes a Python function, validates syntax, scans for dangerous patterns (eval, exec, etc.), and appends it to mcp/server.py. Requires:
