Agent use
Use Deep Research Evidence Builder MCP through stackfast.framework.route, stackfast.framework.invoke, stackfast.framework.validate_output, stackfast.framework.apply_mask, stackfast.framework.trace.

Connector proof
Catalog is not the same as customer-ready.
This product only becomes market-ready after a real host mounts the entitled tools, a safe call succeeds, metering records the event, and a customer-safe receipt exists. Until then, the page shows the strongest proven status without rounding up.

Entitlement
Execution requires OAuth or storefront entitlement scope.
Callable
5 tool(s) declared with no missing V1 tools.
Metering
MCP calls are routed through the metering receipt path.
