Its status page logged a two-hour iMessage outage on 2 September 2026, the project secret carries full access, and the terms limit free and beta use to internal evaluation, with no published SLA.\n\n**Sinch Messaging APIs + MCP.** The Conversation API covers SMS, RCS, WhatsApp, Viber and Messenger through one message format. The MCP server is a developer preview whose npm release dates from 2026-04-14.\n\n## Before you call either\n\n### Photon\n\n1. Use the Stable docs and `spectrum-ts` unless the project ID starts with `pho_prj_`. Stable and Beta packages, hosts and credentials don't mix\n2. Design flows so the person texts first. Photon ties line flags to cold outreach, bursts and more than two or three follow-ups\n3. Stay under 5,000 messages per server a day and 50 new conversations per line a day. Further sends are rejected until the window resets\n4. Give each outbound message a stable `clientGuid` so a retried job doesn't send it twice\n5. Dedupe webhooks on `X-Spectrum-Webhook-Id` plus the event's own id, answer within 30 seconds, and reconcile, because events are dropped after six attempts\n6. Keep the project secret out of the agent's context. It grants full management access and doesn't expire\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## Questions\n\n### Which is better for AI agents, Photon or Sinch Messaging APIs + MCP?\n\nSinch Messaging APIs + MCP scores 63.2 (B) on agent readiness against Photon's 53.5 (D), and leads in 6 of 7 scored categories. Photon leads on agent ergonomics.\n\n### Can an agent call Photon and Sinch Messaging APIs + MCP without installing anything?\n\nYes.
