## Before you call it

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

## Connect

```bash
curl -X POST https://api.brevo.com/v3/smtp/email -H "api-key: $BREVO_API_KEY" \
  -H "Content-Type: application/json" -d '{"sender":{"email":"you@example.com"},"to":[{"email":"them@example.com"}],"subject":"Hello","textContent":"Hello from Brevo"}'
```

```bash
claude mcp add --transport http brevo https://mcp.brevo.com/v1/brevo/mcp --header "Authorization: Bearer $BREVO_MCP_TOKEN"
```
