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

Plivo API

  1. Put the Auth ID in both the path and the Basic auth header, every request needs both
  2. Stay under 300 API requests per 5 seconds, a 429 carries no Retry-After
  3. Give each agent its own subaccount to isolate credentials and spend
  4. Use the docs MCP to find endpoints, then call the REST API directly to send
