The MCP server is a developer preview whose npm release dates from 2026-04-14.\n\n## Before you call either\n\n### Infobip API + MCP\n\n1. Use the account's own base URL (\u003csubdomain\u003e.api.infobip.com), not a generic host\n2. Connect only the MCP server for the channel you need, the RCS server alone has 27 tools\n3. Create a key with only the scopes the agent needs and an expiry date\n4. Send trial messages from ServiceSMS to verified numbers only (up to 5)\n\n### Sinch Messaging APIs + MCP\n\n1. Load the MCP with `--tags` for the channels you need, or all 54 tools land in context\n2. Keep a single-tenant HTTP MCP bound to localhost, it does no inbound authentication\n3. Expect sends to drain at 20 messages a second per app unless Sinch raises it\n4. Verify `x-sinch-webhook-signature` against the raw body before parsing the JSON\n5.
