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.

whatsapp_status

Get the WhatsApp connection status: whether connected, whether pairing (QR scan) is needed, the bot's own JID, and how many messages are buffered.

whatsapp_send

Send a WhatsApp text message. 'to' may be a raw phone number (digits, country code, no +) or a full JID (…@s.whatsapp.net for a person, …@g.us for a group).

whatsapp_send_image

Send an image from a local absolute file path. The file must exist and be a valid image (jpg, png, gif, webp, etc.).

whatsapp_list_chats

List recent chats seen since the server started, newest first, with the last message preview.

whatsapp_get_messages

Get buffered incoming messages, newest first. Optionally filter by chatId and/or a 'since' epoch-ms timestamp, and cap with 'limit'.

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

5/5 tools missing one or more hints — whatsapp_status (missing: readOnlyHint, destructiveHint, idempotentHint, openWorldHint); whatsapp_send (missing: readOnlyHint, destructiveHint, idempotentHint, openWorldHint); whatsapp_send_image (missing: readOnlyHint, destructiveHint, idempotentHint, openWorldHint), +2 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.

Tests exist

No test files found

Add tests that exercise each declared tool.

Production dependencies are patched

1 critical, 1 high severity in production deps — @whiskeysockets/baileys@7.0.0-rc.13 (critical), @modelcontextprotocol/sdk@1.0.4 (high)

Run npm audit fix, or upgrade the affected packages to a non-vulnerable version.

// 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 4 concrete improvements we can share with the publisher of this MCP. Each comes with specific guidance to raise the trust score.
