Capabilities
Backend capabilities
Prostir combines a simple builder, agent resources, searchable knowledge, API-backed tools, users, auth, payments, quotas, and a dedicated runtime into one publishing workflow.
Knowledge
Attach files as resources, searchable Markdown-LD knowledge, or both.
API tools
Publish safe actions for external APIs, existing systems, JavaScript tools, or upstream MCP connections.
Access
Keep users, auth, subscriptions, customer grants, and runtime quotas server-side.
Boundaries
The builder stays simple because the backend stays behind it.
The browser talks to the API. AI clients talk to the MCP runtime. Azure Cosmos DB Serverless remains the source of truth while runtime coordination projects live state and limits.

- Authenticated agent builder
- API-owned auth and billing
Runtime
Runtime complexity stays behind the product boundary.
