Can I use this for both hypothetical and actual testing?

Yes, the framework supports 'Hypothetical Tracing Mode' for reasoning about UI output and 'Actual Tool Calling Mode' for verifying real HTTP endpoint responses.

Does this skill require external tools?

Yes, the framework utilizes Playwright to navigate through the frontend of your application for turn-based evaluation.

How does this framework assess product fit?

It evaluates if the tool-to-widget chain delivers the promised value proposition to a specific persona, comparing the experience against manual or non-AI alternatives.

What is an MCP failure pattern?

These are specific UX issues unique to AI-driven apps, such as 'tool ping-pong' (sequential calls that should be batched) or 'widget mismatch' (displaying data in an inappropriate format).

Security & Testing

Evaluates Model Context Protocol (MCP) applications for product fit, value delivery, and user experience using automated persona-based walkthroughs.

About

The MCP Evaluation Framework is a specialized skill designed to bridge the gap between technical MCP tool implementation and actual user value. It systematically assesses how users interact with MCP-powered applications by simulating target personas and walking through UI flows via Playwright. By identifying specific failure patterns like 'tool ping-pong' or 'widget mismatch,' it provides actionable feedback across tool schemas, outputs, and interface layers, ensuring that AI-driven features deliver a compelling and repeatable product experience.

Key Features

Turn-by-turn value delivery assessment for tool-to-widget transitions
