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.

dynamic_tool_88
screenshot

Capture the current screen as a PNG image (your main way to see it).

get_screen_size

Get the screen size in pixels {width,height} — the coordinate space for click/move.

move

Move the mouse to absolute pixel (x,y).

click

Click at absolute pixel (x,y). button = left|right|middle.

type_text

Type literal text at the current focus.

press_key

Press a key or chord: 'enter', 'ctrl+c', 'super' (opens Start/Spotlight).

// environment variables
To run this server yourself, you supply these values. They go in your own MCP client configuration and stay on your machine. The secret label means the value is sensitive, not that the server mishandles it.

Tool annotations

No tools have read-only/destructive annotations

Add readOnlyHint or destructiveHint annotations to every tool so hosts can warn users before invoking.

All four hints declared on every tool

7/7 tools missing one or more hints — dynamic_tool_88 (missing: readOnlyHint, destructiveHint, idempotentHint, openWorldHint); screenshot (missing: readOnlyHint, destructiveHint, idempotentHint, openWorldHint); get_screen_size (missing: readOnlyHint, destructiveHint, idempotentHint, openWorldHint), +4 more. OpenAI's directory rejects tools where any of the four hints are missing or non-boolean.

For every tool, set all four hints (readOnlyHint, destructiveHint, idempotentHint, openWorldHint) to explicit true/false values that match the handler’s actual behaviour.

Readable source code

1 file are minified or bundled, which is usually build output rather than concealment

// 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 3 concrete improvements we can share with the publisher of this MCP. Each comes with specific guidance to raise the trust score.
