guarded-computer-use-mcp

// key findings
⚠️
Tool annotations don’t match behaviour
1 read-only tool performs write/delete/exec — ocr (line 756: (await import('node:fs/promises')).unlink(shot.path))
No credential exfiltration, no sensitive file access, no obfuscation
Static analysis found nothing flowing your secrets to unexpected places.
Open source with a license and README
Anyone can audit the code, the license is declared, and the publisher documents what it does.

These names and descriptions are the publisher's own, read from the source code. We print them as written. Our assessment is the findings above, not this list.

screenshot
zoom

Capture a small region at native resolution — use this to read fine detail such as UI labels or icons.

screen_hash
wait_for_change
batch
bench

Time each stage of the screenshot pipeline across encoding/scale variants. Diagnostic only.

cursor_position

Current mouse cursor position in physical pixels.

list_displays

All monitors with their bounds in the virtual desktop coordinate space.

list_windows

All visible top-level windows with title, pid, minimized state and rect.

active_window

The foreground window (handle, pid, process name, title, rect).

clipboard_read

Read the clipboard as text.

mouse_move

Move the cursor to (x, y) without clicking.

click

Click at (x, y), or at the current cursor position when x/y are omitted. count=2 for a double click.

drag

Press at (x1, y1), move to (x2, y2), release. The move is interpolated in steps for reliability.

scroll

Scroll the wheel at (x, y) (moves the cursor there first when given). amount is in wheel notches.

type_text
key

Press a key or chord, e.g. "enter", "esc", "f5", "ctrl+c", "ctrl+shift+s", "alt+f4", "win+d".

hold_key

Hold a key down for a duration (ms), e.g. to charge or repeat.

activate_window
ocr
find_elements
click_element
ui_tree
launch_app
clipboard_write

Put text on the clipboard. Useful when typing into an app that mangles direct input.

wait

Sleep for a number of milliseconds — use between an action and the screenshot that verifies it.

Tool annotations match behaviour

1 read-only tool performs write/delete/exec — ocr (line 756: (await import('node:fs/promises')).unlink(shot.path))

Either remove the readOnlyHint:true annotation, or remove the write/delete call from the tool handler.

Destructive tools are labelled

1 tool perform destructive updates without destructiveHint — ocr deletes at line 756 ((await import('node:fs/promises')).unlink(shot.path))

Add destructiveHint:true to any tool whose handler calls .delete(), .upsert(), .update(), unlink, rm, DELETE, DROP, REPLACE INTO, or any operation that overwrites existing data.

// full audit trail
The findings above are the summary. The full trail, every check we ran, each deduction, the network hosts observed and the dependency advisories, goes to verified publishers, along with an alert whenever a new one lands. Verified publishers can also review each finding and dispute it in one click. Publisher corrections have sharpened several of our checks this month, because the maintainer knows the codebase better than any scanner.
// improvement guidance — verified publishers only
We have 2 concrete improvements we can share with the publisher of this MCP. Each comes with specific guidance to raise the trust score.
