## Quality 83/100 (good)

### protocol: 75 (weight 25)

- warn `protocol.modern`: newest supported version is 2025-11-25; 2026-07-28 not supported, older versions are deprecated until 2027-07-28
- n/a `protocol.stateless`: only applies to 2026-07-28 servers
- pass `protocol.transport`: streamable HTTP
- n/a `protocol.list_ttl`: only applies to 2026-07-28 servers

### authorization: n/a (weight 15)

- n/a `auth.prm`, `auth.as_metadata`, `auth.cimd`: no remote uses OAuth
- n/a `auth.secret_in_url`: no templated URL

### tool hygiene: 71 (weight 30)

- pass `tools.descriptions`: every tool has a description
- pass `tools.description_length`: descriptions are concise
- pass `tools.schemas`: every tool has an object input schema
- fail `tools.annotations`: no tool declares readOnlyHint or destructiveHint, so clients cannot tell safe calls from risky ones
- fail `tools.directory_hints`: no tool declares all four of readOnlyHint, destructiveHint, idempotentHint and openWorldHint; missing: upgrade (readOnlyHint, destructiveHint, idempotentHint, openWorldHint); ask (readOnlyHint, destructiveHint, idempotentHint, openWorldHint); notify (readOnlyHint, destructiveHint, idempotentHint, openWorldHint); …
- pass `tools.token_cost`: about 662 tokens to load every tool
- pass `tools.api_dump`: tools are not a one-to-one API dump

### stability: 100 (weight 15)

- pass `stability.changes`: no tool changes in 30 days
- pass `stability.rug_pull`: no tool changed its meaning under the same name

### dependencies: 100 (weight 15)

- pass `deps.known_vulns`: no known advisory in 32 resolved packages
- pass `deps.mcp_sdk_version`: mcp 2.2.0, no known advisory
- pass `deps.resolvable`: pingwa@0.4.1 resolved: 32 packages

- tools: 5, about 662 tokens to load them all

- badge: [![protogrid quality](https://protogrid.dev/badge/io.github.grzgrzgrz3/pingwa.svg)](https://protogrid.dev/servers/io.github.grzgrzgrz3/pingwa)
- Checks run on what our credential-free, read-only probes observe; tools are never called and no code audit is performed.

## Tools (5)

- `ask`: 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`.
        
- `check_replies`: 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.
        
- `check_status`: Show the pingwa account's plan, remaining monthly quota, and whether the
        free 24h WhatsApp reply window is currently open.
- `notify`: 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.
        
- `upgrade`: 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.
