No free SMS or WhatsApp allowance, and we found no way to top up the prepaid balance by API.\n\n**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.\n\n## Before you call either\n\n### Bird API + MCP\n\n1. Read RateLimit-Policy on each response to learn your quota, it isn't in the docs\n2. Send an Idempotency-Key on writes, and change it if the body changes or you'll get 409 E01005\n3. Treat `accepted` as received by Bird, then read the message back to confirm delivery\n4. Connect to mcp.bird.com/dynamic if your client struggles with large tool lists\n5. Log in with `--scope` or `--yolo` before sending, the default CLI login is read-only\n\n### Telnyx API + MCP\n\n1. Register the 10DLC brand ($4.50) and campaign ($10 a month) before sending US long code traffic\n2. Back off on error 10011 for as long as the Retry-After header says\n3. Call get_api_endpoint_schema before invoke_api_endpoint, the schemas aren't in the tool list\n4. Give each agent its own key, since keys can't be scoped\n5. Verify the signature on inbound message webhooks before acting on the text\n\n## Other comparisons with Bird API + MCP or Telnyx API + MCP\n\n- [Bandwidth Messaging API + MCP vs Bird API + MCP](https://www.anchorterminal.com/compare/bandwidth-vs-bird.md)\n- [Bandwidth Messaging API + MCP vs Telnyx API + MCP](https://www.anchorterminal.com/compare/bandwidth-vs-telnyx.md)\n- [Bird API + MCP vs ClickSend SMS API + MCP](https://www.anchorterminal.com/compare/bird-vs-clicksend.md)\n- [Bird API + MCP vs Infobip API + MCP](https://www.anchorterminal.com/compare/bird-vs-infobip.md)\n- [Bird API + MCP vs Plivo API](https://www.anchorterminal.com/compare/bird-vs-plivo.md)\n- [Bird API + MCP vs Sinch Messaging APIs + MCP](https://www.anchorterminal.com/compare/bird-vs-sinch.md)\n- [Bird API + MCP vs Twilio API + MCP](https://www.anchorterminal.com/compare/bird-vs-twilio.md)\n- [Bird API + MCP vs Vonage Messages API + MCP](https://www.anchorterminal.com/compare/bird-vs-vonage.md)\n- [ClickSend SMS API + MCP vs Telnyx API + MCP](https://www.anchorterminal.com/compare/clicksend-vs-telnyx.md)\n- [Infobip API + MCP vs Telnyx API + MCP](https://www.anchorterminal.com/compare/infobip-vs-telnyx.md)\n- [Plivo API vs Telnyx API + MCP](https://www.anchorterminal.com/compare/plivo-vs-telnyx.md)\n- [Sinch Messaging APIs + MCP vs Telnyx API + MCP](https://www.anchorterminal.com/compare/sinch-vs-telnyx.md)\n- [Telnyx API + MCP vs Twilio API + MCP](https://www.anchorterminal.com/compare/telnyx-vs-twilio.md)\n- [Telnyx API + MCP vs Vonage Messages API + MCP](https://www.anchorterminal.com/compare/telnyx-vs-vonage.md)\n- [360dialog WhatsApp API + MCP vs Bird API + MCP](https://www.anchorterminal.com/compare/360dialog-vs-bird.md)\n- [360dialog WhatsApp API + MCP vs Telnyx API + MCP](https://www.anchorterminal.com/compare/360dialog-vs-telnyx.md)\n", "meta": { "attribution": "Anchor Terminal (https://www.anchorterminal.com)", "docs": "https://www.anchorterminal.com/docs/", "generatedAt": "2026-10-05", "license": "CC-BY-4.0", "method": "https://www.anchorterminal.com/benchmark/", "methodology": "0.3", "openapi": "https://www.anchorterminal.com/openapi.json", "preview": false, "run": "2026-10-01", "runLabel": "October 2026 research run" }, "page": { "breadcrumbs": [ { "name": "Home", "url": "https://www.anchorterminal.com/" }, { "name": "Compare", "url": "https://www.anchorterminal.com/compare/" }, { "name": "Bird API + MCP vs Telnyx API + MCP", "url": "" } ], "description": "Bird API + MCP has a score of 77.7 (BB) against Telnyx API + MCP's 73.8 (BB).
