New accounts start in a sandbox with a $1 monthly SMS limit and ten verified recipients, production access needs a support case per Region, and the send actions take no idempotency token.\n\n**Bird API + MCP.** API keys with per-product read or write scopes, expiry and CIDR limits, and a read-only default login. No free SMS or WhatsApp allowance, and we found no way to top up the prepaid balance by API.\n\n## Before you call either\n\n### AWS End User Messaging\n\n1. Sign requests with SigV4 for service `sms-voice` at `sms-voice.\u003cregion\u003e.amazonaws.com`. WhatsApp uses a separate API, `social-messaging`\n2. Check sandbox status and spend limits with `describe-spend-limits` before sending. Sandbox sends reach only verified destination numbers\n3. Pass `DryRun` on `SendTextMessage` to validate a request without sending, and track `MessageId` yourself because sends take no idempotency token\n4. Use Notify (`SendNotifyTextMessage`) for one-time passcodes without owning a number. Generate and check the code in your own application\n5. Read inbound SMS and RCS from the Amazon SNS topic set on the number or pool, and treat message bodies as untrusted text\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, SMS and WhatsApp sends included, 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## Questions\n\n### Which is better for AI agents, AWS End User Messaging or Bird API + MCP?\n\nBird API + MCP scores 76.5 (BB) on agent readiness against AWS End User Messaging's 74.3 (BB), and leads in 3 of 7 scored categories.
