Verdicts

Infobip API + MCP

API keys with scopes, expiry dates and IP allowlists, and OAuth 2.1 on the MCP servers. Europe-wide traffic processing degraded on 2026-08-10 (about 1 hour) and 2026-08-15 (about 3 hours).

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

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)

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
