## 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.

**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

### 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

### 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
