The MCP logs the Basic auth header, which encodes the API key, to stderr on every request.\n\n**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).\n\n## Before you call either\n\n### ClickSend SMS API + MCP\n\n1. Call calculate-sms-price before a bulk send, the pricing endpoint needs no key\n2. Pass the user's own date words in user_date_request when reading SMS history\n3. Use a subaccount key for the agent, not the main account key\n4. Restrict access to the MCP host's log files, they contain the encoded API key\n5. Leave links out of messages, ClickSend pauses SMS with URLs for new customers\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.
