Keep under 10 requests a second, or tell Streak first, since there's no published hard limit\n2. Expect no email bodies through MCP and fetch thread context through Gmail instead\n3. Send the API key as the Basic auth username with an empty password\n4. Check the plan before relying on webhooks, which start at Pro+\n5.
