## Trust breakdown

How this component scores in each security and reliability category. Every signal is checked automatically against the live server, and we only credit what we can confirm. Scores are 0–100 per category. Scoring method: https://verifymcp.io/docs/scoring (what has changed: https://verifymcp.io/docs/scoring/changelog)

Scored 2026-08-04.

- **Endpoint Security**: 46/100
  - The endpoint's TLS certificate is valid, in date, and uses a strong key.
  - Authorisation not fully verified: no authorisation is required to call this server, and 5 tool(s) never declared a destructiveHint. The MCP spec treats an absent hint as destructive by default, so we cannot call this surface safe.
  - HTTPS not yet verified: we couldn't determine whether a plaintext access path exists.
  - HSTS check failed: the Strict-Transport-Security header is absent.
  - DNSSEC check failed: this domain isn't protected by DNSSEC.
- **Transport & Reachability**: 100/100
  - Verified streamable-http transport via a live MCP handshake.
- **Schema Quality & AI Usability**: 74/100
  - AI-judged instruction clarity (excellent).
  - Context-footprint check failed: tool/resource definitions use about 682 tokens (~136/item across 5 items; 5 tools + 0 resources), over budget; trim descriptions and params.
  - Usage-examples check failed: none of the tools include examples.
- **Stability & Change Management**: 30/100
  - Stability observed for 9 of 30 days with no destabilising changes; credit accrues until the full window elapses.
- **Tool Coverage**: 71/100
  - 100% of tools have a non-trivial description (not blank, and not just the tool's name).
  - 0% of tool parameters carry a description.
  - Structured output schemas are declared (100% of tools); any adoption earns full credit.
- **Capabilities**: 100/100
  - Implements a supported MCP spec version (2025-11-25); the latest is 2026-07-28.

First indexed and scored.

## MCP tools (5)

### `notify` (~116 tokens)

Send a WhatsApp notification to the account owner's own phone.

        `text` is the message (1-1024 chars). `image_url` (optional) is a public https
        image link — a screenshot, chart or diff — delivered as an image with `text` as
        the caption when the user's 24h window is open (otherwise text only). Returns a
        confirmation with the queued message id; raises an actionable error on quota/auth.

Input parameters:

- `image_url`
- `text` (string, required)

Output parameters:

- `result` (string)

### `check_status` (~37 tokens)

Show the pingwa account's plan, remaining monthly quota, and whether the
        free 24h WhatsApp reply window is currently open.

Output parameters:

- `result` (string)

### `upgrade` (~73 tokens)

Get a link to upgrade the account to Pro (raises the monthly quota).

        Returns a Stripe Checkout URL for the human to open and pay — no pingwa
        password needed, the card is handled by Stripe. If the account is already
        Pro, returns a billing-portal URL to manage or cancel instead.

Output parameters:

- `result` (string)

### `ask` (~155 tokens)

Ask the human a question on WhatsApp and BLOCK until they reply (or timeout).

        `text` is the question. `buttons` (optional, up to 3) render as tappable reply
        buttons; omit them to invite a free-text answer the human types on their phone —
        use this to let the human steer you mid-task. `timeout` is seconds to wait
        (max 90). Returns the human's reply (free text and/or the chosen option). On
        timeout, returns a note — the question was delivered and the answer is still
        retrievable via `check_replies`.

Input parameters:

- `buttons`
- `text` (string, required)
- `timeout` (integer)

Output parameters:

- `result` (string)

### `check_replies` (~97 tokens)

Pull inbound WhatsApp messages the human sent to pingwa (out-of-band
        instructions, or late answers to an `ask`). `since` is a cursor from a previous
        call (pass it back to get only newer messages); `wait` long-polls up to that many
        seconds for something to arrive. Returns the messages and a new cursor.

Input parameters:

- `since`
- `wait` (integer)

Output parameters:

- `result` (string)
