APPROVAL GATE
Zero Direct Deletion
Agents can only propose cleanup plans. Destructive actions strictly require human approval in the desktop app.

$ claude "Can I safely run this 18 GB docker build?"
mcp.call("preflight_check", expectedBytes: 18 GB)
[Shortfall]: Needs 18 GB + 2 GB headroom. Current free: 14.2 GB.
Action: SpaceWise identifies 24.8 GB of reclaimable DerivedData & Docker cache.

HOW IT WORKS
Safe by design at every step.
SpaceWise treats AI coding agents as intelligent draft creators, not root disk administrators.
CONTAINMENT
Protected Projects
Your active workspace roots and current working directory are strictly protected. Neither files inside nor parent folders can be wiped.
CRASH PREVENTION
Active App Guard
Checks running processes before cleaning. If Xcode, Docker, or simulators are open, their caches are automatically skipped.
RESTORE ROLLBACK
Recovery Bin Quarantine
Cleanups move items into the SpaceWise Recovery Bin and native OS Trash. No hard unlinking. Instant 1-click restore.
SANITIZATION
Prompt Injection Defense
Folder names and paths are stripped of ANSI escape codes, terminal control characters, and truncated to safe lengths.
LOCAL IPC
0600 Owner-Only Socket
Communicates over a local Unix domain socket or Windows Named Pipe with 256-bit unguessable tokens. Zero cloud telemetry.
TOOL REGISTRY
The 6 tools exposed to your agent.
Typed Zod schemas with deterministic outputs, zero hallucinated paths, and live visual gateway feedback.

FREQUENTLY ASKED QUESTIONS
Everything you need to know
Clear answers about safety, privacy, containment, and agent execution.
Can an AI coding agent delete my project files or git repository?
No. SpaceWise uses bidirectional containment: workspace roots advertised by your IDE or CLI and your current working directory cannot be touched or traversed upward. Furthermore, agents can only draft dry-run plans; every cleanup requires your explicit approval in the desktop application.
Where do files go when a cleanup plan runs?
Files are evacuated to the SpaceWise Recovery Bin (~/.spacewise/recovery-bin/) and your native OS Trash. No permanent rm -rf is ever executed. You can restore any cleaned target with one click from the Activity tab.
What happens if an agent tries to execute a plan before I approve it?
The call immediately returns pending_approval without blocking or touching any file. SpaceWise fails closed; only plans explicitly approved by you inside the desktop app can be executed.
Does SpaceWise MCP send my files, filenames, or disk metrics to any cloud?
Never. SpaceWise MCP operates entirely on your local machine over an authenticated Unix domain socket (or Windows named pipe) with owner-only (0600) permissions. Zero external telemetry, zero network tracking.
How do I install and configure the MCP server?
For Claude Code, run: claude mcp add spacewise -- npx -y spacewise-mcp. For Cursor, add spacewise to ~/.cursor/mcp.json. For Codex CLI, add it to ~/.codex/config.toml. The bridge runs via npx with zero local build steps.
