Available components
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. How we score → Why this is hard to score →
Endpoint Security60
- The endpoint's TLS certificate is valid, in date, and uses a strong key. View diagnostics → Pass
- Authorisation not fully verified: no authorisation is required to call this server, and 8 tool(s) never declared a destructiveHint. The MCP spec treats an absent hint as destructive by default, so we cannot call this surface safe. See how to fix → View diagnostics → Unverified
- HTTPS is enforced; there's no plaintext access path. View diagnostics → Pass
- HSTS check failed: the Strict-Transport-Security header is absent. See how to fix → View diagnostics → Fail
- DNSSEC is configured correctly; the domain's records validate against the full chain to the root. View diagnostics → Pass
Transport & Reachability100
- Verified streamable-http transport via a live MCP handshake. View diagnostics → Pass
Schema Quality & AI Usability67
- AI-judged instruction clarity (excellent).Pass
- Context-footprint check failed: tool/resource definitions use about 1707 tokens (~213/item across 8 items; 8 tools + 0 resources), over budget; trim descriptions and params. See how to fix → Fail
- Usage-examples check failed: none of the tools include examples. See how to fix → Fail
Stability & Change Management100
- No destabilizing schema changes in the last 30 days.Pass
Tool Coverage100
- 100% of tools have a non-trivial description (not blank, and not just the tool's name).Pass
- 100% of tool parameters carry a description.Pass
Tool Safety100
- No prompt-injection markers were found in the server instructions, tool names or descriptions we captured.Pass
- We read all 8 captured tool definition(s), and no name or description among them implies an irreversible operation.Pass
- An AI judge read all 9 captured unit(s) of tool text and found none that tries to manipulate the model reading it.Pass
Capabilities60
- Spec-recency check failed: implements MCP spec 2025-06-18; the latest is 2026-07-28. See how to fix → Fail

The tools this component advertises to a client, with an estimated token cost for each. Expand a tool to see its parameters and schema. The per-tool counts are indicative and are not scored directly; the schema's total context footprint is one signal in Schema Quality & AI Usability. A tool's description is untrusted text the model reads on every call, which is what makes this list a security surface and not just an inventory: how tool poisoning works →
build_whatsapp_share_widget ~191
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.
| Name | Type | Req | Description |
|---|---|---|---|
| buttonPlacement | string | – | Where to place the share button relative to the card (optional). |
| buttonText | string | – | Call-to-action button text (optional; defaults to "Share on WhatsApp"). |
| description | string | yes | Message text shown above the card (supports *bold*, _italic_, ~strike~). |

| includeCredit | boolean | – | Append a small "Widget by wha.tools" credit line under the widget (optional; default false). |
| thumbnail | string | – | Preview image URL (optional). |
| title | string | yes | Title shown on the preview card. |
| url | string | yes | The URL being shared. |

estimate_whatsapp_api_cost ~346
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.
| Name | Type | Req | Description |
|---|---|---|---|
| authentication | number | – | Monthly count of authentication template messages (one-time passcodes). |
| market | string | yes | Recipient market as a 2-letter code (e.g. "US", "IN", "BR", "GB", "DE"), or "ROW" for rest of world. Rates vary widely by market. |
| marketing | number | – | Monthly count of marketing template messages (promotions, offers). |
| service | number | – | Monthly count of service messages (free-form replies inside a customer-opened window). Optional. When given, the first 1,000 per phone number each month are free and the rest bill at the market's uti… |
| utility | number | – | Monthly count of utility template messages (order updates, receipts, reminders). |
No output schema declared.
No examples provided.
generate_bulk_whatsapp_links ~274
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.
| Name | Type | Req | Description |
|---|---|---|---|
| contacts | array | yes | Up to 500 contacts. Each needs a "phone" (international format, digits only) plus any placeholder fields as string properties. |
| template | string | yes | Message template with {{field}} placeholders, e.g. 'Hello {{name}}, see you at {{time}}'. Supports {{field|fallback}} defaults, {{FirstName}} derived from a name field, and {{a|b|c}} spintax variatio… |

generate_whatsapp_link ~87
Generate a WhatsApp click-to-chat (wa.me) link with an optional phone number and pre-filled message. Runs locally; no message is sent.
| Name | Type | Req | Description |
|---|---|---|---|
| message | string | – | The message to pre-fill in the chat (optional). |
| phone | string | – | Recipient phone number in international format (digits only; optional). Omit to create a share link with no specific recipient. |
No output schema declared.
No examples provided.
generate_whatsapp_qr ~76
Generate a scannable QR code (as an SVG) for a WhatsApp click-to-chat link with an optional phone number and pre-filled message.
| Name | Type | Req | Description |
|---|---|---|---|
| message | string | – | The message to pre-fill in the chat (optional). |
| phone | string | – | Recipient phone number in international format (digits only; optional). |
No output schema declared.
No examples provided.
get_whatsapp_limits ~157
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.
| Name | Type | Req | Description |
|---|---|---|---|
| area | string | – | Restrict the result to one area (e.g. "groups", "messages", "calls", "channels", "account", "business", "api"). Optional; omit for every area. |
No output schema declared.
No examples provided.
get_whatsapp_rates ~335
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.
| Name | Type | Req | Description |
|---|---|---|---|
| currency | string | – | One of the 16 currencies Meta publishes a card in (USD, EUR, GBP, INR, IDR, BRL, MXN, ARS, COP, AED, SAR, AUD, MYR, PEN, CLP, SGD). Rates are stored per currency exactly as Meta prints them, never co… |
| include_tiers | boolean | – | When a single market is given, also return that market's published volume-tier thresholds and per-band rates for utility and authentication. Ignored when no market is given. Optional, default false. |
| market | string | – | Recipient market as a 2-letter code (e.g. "US"/"NA", "IN", "BR", "GB", "DE") or a "Rest of" region id. Omit to return the whole rate card for the chosen currency. |
No output schema declared.
No examples provided.
validate_phone_number ~168
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.
| Name | Type | Req | Description |
|---|---|---|---|
| country | string | – | ISO 3166-1 alpha-2 country code (e.g. "GB", "US") assumed when the number has no country code. Optional. |
| phone | string | yes | The phone number to validate. International format with a leading "+" is best; otherwise also pass `country`. |
No output schema declared.
No examples provided.
