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### Vonage Messages API + MCP\n\n1. Keep api.nexmo.com as the host, don't rewrite it to vonage.com\n2. Use the Messages API, not the legacy SMS API\n3. Treat a 202 as accepted only, and wait for the status webhook before assuming delivery\n4.
