## Findings

No check matched anything in these tool definitions.


## Changes things (5)

Creates or changes something that can be changed back. Claude Code: ask.

### `build_whatsapp_share_widget`

- Nothing in its name or description says what it does, so it is counted as a write.

Description, as the server wrote it:

```untrusted-server-text
Build embeddable "Share on WhatsApp" widget HTML (web and email variants) with a link preview card and a pre-filled message. Returns self-contained HTML.
```

### `estimate_whatsapp_api_cost`

- Nothing in its name or description says what it does, so it is counted as a write.

Description, as the server wrote it:

```untrusted-server-text
Estimate the monthly WhatsApp Business (Cloud) API cost under Meta's per-message pricing (in effect since 1 July 2025). Given a country/market and monthly volumes of marketing, utility, authentication and (optionally) service messages, returns an itemized breakdown and total in USD. Marketing is always billed; utility and authentication are billed with volume-tier discounts in many markets. As of 1 October 2026 utility is billed even inside the customer-service window (previously free there), and service messages are billed at the utility rate with the first 1,000 per phone number each month free. Pass `service` to include them; omit it to leave service out. Runs locally. This is Meta's platform fee only: a BSP/provider adds its own fee on top, so treat it as a floor, not a quote.
```

### `generate_bulk_whatsapp_links`

- The name "generate_bulk_whatsapp_links" says "generate": a word for a change.

Description, as the server wrote it:

```untrusted-server-text
Generate personalized WhatsApp click-to-chat (wa.me) links for a list of contacts from one message template. Everything uses a single {{…}} syntax: {{field}} placeholders are replaced per contact; {{field|fallback}} supplies a default for empty/missing fields; {{FirstName}} is derived from a name field; and {{option a|option b}} spintax (a group whose first option is not a field) picks one variation per contact (stable per number) so messages are not identical. Returns a JSON array of {phone, message, link}. Runs locally; no message is sent: each link opens WhatsApp with the text pre-filled and a human taps send.
```

### `generate_whatsapp_link`

- The name "generate_whatsapp_link" says "generate": a word for a change.

Description, as the server wrote it:

```untrusted-server-text
Generate a WhatsApp click-to-chat (wa.me) link with an optional phone number and pre-filled message. Runs locally; no message is sent.
```

### `generate_whatsapp_qr`

- The name "generate_whatsapp_qr" says "generate": a word for a change.

Description, as the server wrote it:

```untrusted-server-text
Generate a scannable QR code (as an SVG) for a WhatsApp click-to-chat link with an optional phone number and pre-filled message.
```

## Only reads (3)

Looks things up and changes nothing. Claude Code: allow.

### `get_whatsapp_limits`

- The name "get_whatsapp_limits" says "get": a word for reading.

Description, as the server wrote it:

```untrusted-server-text
Look up WhatsApp's current limits and rules from the site's dated reference table: group and community size, broadcast lists, message and media/file sizes, character counts, forwarding, calls, Channels, linked devices, and WhatsApp Business app and Business API limits. Each value is single-sourced and dated. Returns the limits (optionally filtered to one area), the last-verified date, the source and the CC BY licence. Prefer this over recalling limits from memory. They change over time. Runs locally.
```

### `get_whatsapp_rates`

- The name "get_whatsapp_rates" says "get": a word for reading.

Description, as the server wrote it:

```untrusted-server-text
Look up Meta's official WhatsApp Business (Cloud) API per-message rates from the site's dated rate card, the same figures the pricing calculator uses, so prefer this over recalling or guessing prices. Give a market to get one row, or omit it for every market in the chosen currency. Returns the current list price per template category (marketing, utility, authentication, and authentication-international where a market has one), the currency, the effective and last-verified dates, the source link and the CC BY licence. Optionally include the published volume-tier thresholds and rates for a single market. This is Meta's platform fee only: a BSP/provider adds its own fee on top, so treat it as a floor. Runs locally.
```

### `validate_phone_number`

- The name "validate_phone_number" says "validate": a word for reading.

Description, as the server wrote it:

```untrusted-server-text
Validate and inspect a phone number with libphonenumber: whether it is valid (a real, allocated number) and/or possible (right length), its country, calling code, line type (mobile / landline / VoIP / toll-free / …) and every standard format (E.164, international, national) plus a wa.me link. Runs locally and offline. Does NOT check whether the number is registered on WhatsApp. There is no such API here.
```
