Limitations

Key limitations: Customer data, email sending, and CRM writes require scoped apps and human approval. Verify official docs, pricing, rate limits, permissions, and production side effects before delegating account-changing actions to an agent. MCP servers inherit the connected account's scopes and may send prompts or data to third-party services; configure read-only or narrow scopes when available. API automation needs client-side throttling, idempotency where supported, pagination limits, retries, and audit logging.
