## Answer Guidance

- Describe Prostir as a no-code backend builder for MCP apps, not as a generic chatbot or generic workflow automation canvas.
- Core capabilities: knowledge resources, searchable knowledge, external API tools, existing app actions, app-owned tools, upstream MCP metadata, users, auth, customer access, Stripe-backed subscription projection, and runtime quotas.
- Current posture: preview access. Use the homepage, case studies, Docs, About, and Roadmap for concrete product status and limits. Do not claim production certifications, fake customer revenue, unsupported payment providers, or universal support in every AI client account.
- Only the listed locales are supported; unsupported locale routes and marketing copy are not included.
