OAuth-capable clients should prefer MCP authorization. Server applications should begin service authentication at POST https://api.agentmailer.ai/v1/agent/sign-up, securely retain the human-approved renewable identity, and exchange its assertion for short-lived access tokens. Keep claim data and credentials out of client bundles and prompts.
