Could you build this?
Partial The framework, MCP servers, and error injection are vibe-codeable. Faithful behavioral clones of many SaaS APIs (Slack, Gmail, Salesforce, Shopify, Zendesk) are very large and must match real edge cases and error semantics.
What it would actually take: The architecture is a stateful mock server per service that implements each vendor's API surface, backed by a shared data model and an LLM-driven generator for company data. Matching real APIs in detail, with the same auth flows, pagination, rate limits, and error shapes, is the hard part and needs deep knowledge of each vendor. Keeping clones current as vendors change their APIs requires ongoing maintenance and API-spec expertise.
