Europe-wide traffic processing degraded on 2026-08-10 (about 1 hour) and 2026-08-15 (about 3 hours). **Telnyx API + MCP.** US long code SMS $0.004 a part outbound and inbound, published with carrier fees and as machine-readable pricing.md. No per-key scopes or read-only keys, and the MCP can send or buy numbers without confirmation. ## Before you call either ### Infobip API + MCP 1. Use the account's own base URL (.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) ### Telnyx API + MCP 1. Register the 10DLC brand ($4.50) and campaign ($10 a month) before sending US long code traffic 2. Back off on error 10011 for as long as the Retry-After header says 3. Call get_api_endpoint_schema before invoke_api_endpoint, the schemas aren't in the tool list 4. Give each agent its own key, since keys can't be scoped 5. Verify the signature on inbound message webhooks before acting on the text ## Other comparisons with Infobip API + MCP or Telnyx API + MCP - [Bandwidth Messaging API + MCP vs Infobip API + MCP](https://www.anchorterminal.com/compare/bandwidth-vs-infobip.md) - [Bandwidth Messaging API + MCP vs Telnyx API + MCP](https://www.anchorterminal.com/compare/bandwidth-vs-telnyx.md) - [Bird API + MCP vs Infobip API + MCP](https://www.anchorterminal.com/compare/bird-vs-infobip.md) - [Bird API + MCP vs Telnyx API + MCP](https://www.anchorterminal.com/compare/bird-vs-telnyx.md) - [ClickSend SMS API + MCP vs Infobip API + MCP](https://www.anchorterminal.com/compare/clicksend-vs-infobip.md) - [ClickSend SMS API + MCP vs Telnyx API + MCP](https://www.anchorterminal.com/compare/clicksend-vs-telnyx.md) - [Infobip API + MCP vs Plivo API](https://www.anchorterminal.com/compare/infobip-vs-plivo.md) - [Infobip API + MCP vs Sinch Messaging APIs + MCP](https://www.anchorterminal.com/compare/infobip-vs-sinch.md) - [Infobip API + MCP vs Twilio API + MCP](https://www.anchorterminal.com/compare/infobip-vs-twilio.md) - [Infobip API + MCP vs Vonage Messages API + MCP](https://www.anchorterminal.com/compare/infobip-vs-vonage.md) - [Plivo API vs Telnyx API + MCP](https://www.anchorterminal.com/compare/plivo-vs-telnyx.md) - [Sinch Messaging APIs + MCP vs Telnyx API + MCP](https://www.anchorterminal.com/compare/sinch-vs-telnyx.md) - [Telnyx API + MCP vs Twilio API + MCP](https://www.anchorterminal.com/compare/telnyx-vs-twilio.md) - [Telnyx API + MCP vs Vonage Messages API + MCP](https://www.anchorterminal.com/compare/telnyx-vs-vonage.md) - [360dialog WhatsApp API + MCP vs Infobip API + MCP](https://www.anchorterminal.com/compare/360dialog-vs-infobip.md) - [360dialog WhatsApp API + MCP vs Telnyx API + MCP](https://www.anchorterminal.com/compare/360dialog-vs-telnyx.md)
