Description
Run User Testing, Swarms, Evals, and CI/CD gates on your MCP server to see if users actually succeed in ChatGPT, Claude, and Copilot. Test local servers via desktop app, CLI, or SDK.

Could you build this?
Partial The CLI, SDK, and simple LLM-eval test harness can be vibe-coded, but running simulated user swarms across multiple proprietary desktop/web clients (ChatGPT, Claude, Copilot) with cross-client parity and local proxying requires complex reverse engineering of client behaviors and state orchestration.
What it would actually take: A full version requires building an MCP client-server proxy, automated headless browser runners, or mock sandboxes that accurately replicate token limits, context handling, and tool-invocation behaviors specific to Claude Desktop, ChatGPT, and Copilot. The backend needs a distributed job runner for parallel agent evaluation simulations (swarms) with LLM-as-a-judge scoring frameworks. This demands deep expertise in protocol design, integration testing harness architecture, and browser automation.

Same idea, different domain
Nobody's really built a observability & eval tool for Media & entertainment yet.
