Burrow system tools

Burrow runs a local MCP server over the user's Mac: live + historical system state (read-only) and gated maintenance. The governing habit is diagnose first — when a question is about this machine, or you spot a system symptom mid-task, reach for the read-only tools, name the cause, then propose a fix. Read-only tools never change anything, so there's no reason to hesitate.

Diagnose first (read-only — always safe)

• burrow_doctor — one-call health sweep: Full Disk Access, memory pressure, disk headroom, SIP / Gatekeeper / FileVault / firewall, battery, sustained high-CPU, display/volume/network. Start here for any vague "something's wrong / is my Mac healthy / is it secure?" — it tells you which area to drill into.
• burrow_snapshot — current vitals (CPU, memory, disk, network, temperature, top processes, a 0–100 health score). For "what's happening right now".
• burrow_top_processes — top CPU right now. For "what's using my CPU / why is it hot or loud?"
• burrow_process_usage — ranks over a window by cpu_time / peak_cpu / avg_cpu / peak_mem. Prefer this for "all day / since this morning / what's draining my battery?"
• burrow_history / burrow_diff — a trend over time, or what changed since a point ("it got slow in the last hour").
• burrow_disk_forecast — "when will my disk fill up?" burrow_analyze <path> — "what's eating space in <folder>?"
• burrow_ports — "what's listening / what's on port 3000?" (pid + owner).
• burrow_cleanup_history / burrow_deleted_files — what Burrow has cleaned, and exactly which files it removed.
• burrow_list_apps — installed apps + the exact names uninstall accepts (call this before any uninstall). burrow_info — whether Burrow is even recording data (use when results look empty or stale).

Then act (gated — preview by default)

Maintenance tools mutate the system. They run dry-run by default; a real run needs confirm: true and the user's Settings opt-in, so a confirmed call may still be refused and reported as blocked. Always show the dry-run preview and get the user's explicit go before passing confirm: true — never assume a real run will execute.

• burrow_clean / burrow_optimize — remove caches/logs/junk / run safe maintenance.
• burrow_uninstall — remove apps + leftovers (to Trash unless permanent; resolve names via burrow_list_apps first; it aborts unless the matcher hits exactly the apps you named).
• burrow_purge / burrow_installer — preview-only over MCP (dev build artifacts / leftover installers); the real run is interactive in the app.

Be proactive

The biggest win is catching problems the user hasn't mentioned. If, mid-task, you hit or notice a system symptom — a build failing because the disk is nearly full, a process pinning the CPU, a port already in use — pause, run the relevant read-only tool, tell the user what you found, and offer the fix. That's the behaviour to lean into; don't wait to be asked.

Patterns

• Slow / hot / loud → burrow_doctor → burrow_top_processes (now) or burrow_process_usage (over time) → name the culprit → offer a clean/optimize preview if relevant.
• Low on disk → burrow_disk_forecast → burrow_analyze <folder> → burrow_purge / burrow_installer previews → burrow_clean preview.
• Security / what's listening → burrow_doctor + burrow_ports.
• Empty or stale results → burrow_info to confirm Burrow is recording.
