POST /v3/smtp/email allows 1,000 requests a second on every plan. Eight 'multiple services' full outages on the status page since July.

Restricted API keys with per-endpoint scopes, subuser keys and IP access management. No official MCP server that can send, only Twilio's docs search.

Connect a single module server at /v1/brevo_<module>/mcp rather than the combined /v1/brevo/mcp
Send with POST /v3/smtp/email and the api-key header, not Bearer
Use webhooks for delivery events. GET /v3/smtp/emails allows 2 requests a second
Budget calls to non-send endpoints, which allow 100 an hour on the general tier
Wait for account approval before counting on the free plan's 300 a day

Give an agent that only sends a restricted key with just mail.send
Set mail_settings.sandbox_mode to validate payloads without delivery
Authenticate a domain or verify a single sender before the first send
Read X-RateLimit-Remaining and X-RateLimit-Reset and wait for the reset on 429
Don't blindly retry a timed-out mail/send. There's no idempotency key, so the message can go out twice
