Before you call either

Infobip API + MCP

  1. Use the account's own base URL (<subdomain>.api.infobip.com), not a generic host
  2. Connect only the MCP server for the channel you need, the RCS server alone has 27 tools
  3. Create a key with only the scopes the agent needs and an expiry date
  4. Send trial messages from ServiceSMS to verified numbers only (up to 5)

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
