Does it support both Python and TypeScript servers?

Yes, the skill includes specialized logic to locate and validate server implementations in both Python (FastMCP/MCP) and TypeScript environments.

Can I use this for security audits?

While it performs a basic security review for secrets and SQL injection, it is intended as a development best-practices tool rather than a comprehensive penetration testing suite.

What is a 'sequential call anti-pattern'?

It occurs when an agent must call one tool to get an ID and then a second tool to get details. This skill helps you merge those into single, more efficient calls.

How does this skill improve AI agent performance?

By ensuring tool descriptions explain exactly *when* to use a tool and providing rich return data, it reduces agent hallucinations and unnecessary API calls.

What does the MCP Server Validator actually check?

It audits tool naming (kebab-case), description quality, sequential call anti-patterns, input schema completeness, actionable error messages, and basic security vulnerabilities.

API開発

Validates Model Context Protocol (MCP) server implementations against industry best practices to ensure high-quality tool performance and security.

The MCP Server Validator is a specialized skill designed to help developers build robust and efficient Model Context Protocol (MCP) servers. It performs a comprehensive audit of tool naming conventions, description quality, input schemas, and error handling patterns. By identifying common anti-patterns—such as sequential calling requirements that hinder agent efficiency—and providing actionable fix suggestions, this skill ensures that your MCP servers are optimized for AI agents, secure from common vulnerabilities, and fully compliant with the latest protocol standards.
