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)

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
