The MCP server is a developer preview whose npm release dates from 2026-04-14.\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### Sinch Messaging APIs + MCP\n\n1. Load the MCP with `--tags` for the channels you need, or all 54 tools land in context\n2. Keep a single-tenant HTTP MCP bound to localhost, it does no inbound authentication\n3. Expect sends to drain at 20 messages a second per app unless Sinch raises it\n4. Verify `x-sinch-webhook-signature` against the raw body before parsing the JSON\n5. Use the regional base URL (us, eu or br) that matches the project\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, Sinch Messaging APIs + MCP or WhatsApp Business Platform (Cloud API)?\n\nWhatsApp Business Platform (Cloud API) scores 67.1 (B) on agent readiness against Sinch Messaging APIs + MCP's 63.2 (B), and leads in 5 of 7 scored categories.
