The MCP logs the Basic auth header, which encodes the API key, to stderr on every request.\n\n**WhatsApp Business Platform (Cloud API).** The first-party WhatsApp API has a public OpenAPI document, Markdown docs with llms.txt, numeric rate limits and a test number that sends without a payment method. Setup needs a person in three Meta dashboards, no idempotency key was found for sends, and Meta's terms restrict general-purpose AI assistants on the platform.\n\n## Before you call either\n\n### ClickSend SMS API + MCP\n\n1. Call calculate-sms-price before a bulk send, the pricing endpoint needs no key\n2. Pass the user's own date words in user_date_request when reading SMS history\n3. Use a subaccount key for the agent, not the main account key\n4. Restrict access to the MCP host's log files, they contain the encoded API key\n5. Leave links out of messages, ClickSend pauses SMS with URLs for new customers\n\n### WhatsApp Business Platform (Cloud API)\n\n1. Check when the user last wrote. Free-form messages are accepted only within 24 hours of the user's last message. After that, send an approved template.\n2. Record the message id from each send and match it to `messages` webhook statuses. Many failures arrive only by webhook, and no idempotency key was found.\n3. On error 130429 or 131056 wait and retry. Meta's guidance for the per-recipient limit is 4^X seconds, with X rising by one per failure.\n4. Verify `X-Hub-Signature-256` with the app secret on every webhook, and deduplicate, because failed deliveries are retried for up to 7 days.\n5. Request `health_status` on the phone number before a campaign to see whether the app, business, account, number and template can send.\n\n## Questions\n\n### Which is better for AI agents, ClickSend SMS API + MCP or WhatsApp Business Platform (Cloud API)?\n\nWhatsApp Business Platform (Cloud API) scores 67.1 (B) on agent readiness against ClickSend SMS API + MCP's 47.7 (D), and leads in 5 of 7 scored categories.
