SYSTEM DOCUMENTATION & REQUIREMENTS

💡 This Skill includes references (resource) components.

What problem does it solve?

This Skill provides a comprehensive guide and framework for creating robust evaluations for MCP servers, ensuring they can effectively answer complex questions using only provided tools.

Core Features & Use Cases

  • Evaluation Framework: Defines requirements for creating human-readable, complex, and verifiable questions.
  • Tool Usage Guidance: Details how LLMs should interact with MCP server tools for read-only, independent, and non-destructive operations.
  • Output Formatting: Specifies the XML structure for evaluation results and provides examples of good and poor question/answer pairs.
  • Use Case: A developer building an MCP server can use this guide to create a suite of challenging test cases that rigorously validate the server's ability to serve an LLM.

Quick Start

Use the universal-main-mcp-builder skill to generate a set of 10 evaluation questions for a new MCP server.

Frequently Asked Questions about universal-main-mcp-builder

High-intent search queries and answers about installing and using this skill.

FAQPage Schema
How do I create evaluation tests for an MCP server?▼

Design MCP server evaluations by generating human-readable questions that require LLMs to interact with tools for complex, read-only operations, verifying answers through a structured XML output format.

What makes a good MCP server evaluation question?▼

A good MCP server evaluation question is human-readable, complex, stable, and requires the LLM to use provided tools for read-only operations to find a verifiable answer.

How do LLMs interact with tools during MCP server testing?▼

During MCP server testing, LLMs interact with tools by executing independent, read-only, and non-destructive operations to gather information needed to answer complex questions.

Do I need to format MCP evaluation results in a specific structure?▼

Yes, MCP evaluation results must be output in a strict XML structure that defines QA pairs, ensuring rigorous validation of the server's ability to serve an LLM.

Can I use this approach to test destructive write operations on my MCP server?▼

No, this evaluation framework focuses exclusively on complex, read-only, and non-destructive tasks to ensure the LLM interacts with the MCP server tools safely and independently.
