Verdicts

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.

Twilio API + MCP

Per-segment US prices, carrier fees by carrier and the $0.001 failed-message fee published without a login. US SMS at $0.0083 a segment plus $0.0035 to $0.005 in carrier fees, with inbound charged at the same rate.

Before you call either

Bird API + MCP

  1. Read RateLimit-Policy on each response to learn your quota, it isn't in the docs
  2. Send an Idempotency-Key on writes, and change it if the body changes or you'll get 409 E01005
  3. Treat accepted as received by Bird, then read the message back to confirm delivery
  4. Connect to mcp.bird.com/dynamic if your client struggles with large tool lists
  5. Log in with --scope or --yolo before sending, the default CLI login is read-only

Twilio API + MCP

  1. Use the hosted docs MCP to find the endpoint, then call the REST API with a restricted API key
  2. Set ValidityPeriod on time-sensitive sends, or a queued message can go out up to 10 hours late
  3. Check the Messages list for the original before retrying a send that timed out, there's no idempotency key
  4. Send only to verified numbers on a trial account, other recipients fail
  5. Validate X-Twilio-Signature on every inbound webhook
