Verdicts

Infobip API + MCP

API keys with scopes, expiry dates and IP allowlists, and OAuth 2.1 on the MCP servers. Europe-wide traffic processing degraded on 2026-08-10 (about 1 hour) and 2026-08-15 (about 3 hours).

Photon

Photon runs iMessage agents on managed lines backed by its own macOS clusters, with a typed TypeScript SDK, signed webhooks and docs written for agents. 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.

Before you call either

Infobip API + MCP

  1. Use the account's own base URL (<subdomain>.api.infobip.com), not a generic host
  2. Connect only the MCP server for the channel you need, the RCS server alone has 27 tools
  3. Create a key with only the scopes the agent needs and an expiry date
  4. Send trial messages from ServiceSMS to verified numbers only (up to 5)

Photon

  1. 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
  2. Design flows so the person texts first. Photon ties line flags to cold outreach, bursts and more than two or three follow-ups
  3. 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
  4. Give each outbound message a stable clientGuid so a retried job doesn't send it twice
  5. 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
  6. Keep the project secret out of the agent's context. It grants full management access and doesn't expire
