MCP Builder

About

MCP Builder provides a comprehensive framework for architecting and implementing robust Model Context Protocol (MCP) servers. It guides developers through the entire lifecycle—from initial API research and tool design to testing with the MCP Inspector and creating automated evaluation suites. By emphasizing best practices in tool naming, context management, and actionable error handling, this skill ensures that external services are exposed to language models in a way that maximizes discoverability and task performance across different execution environments.

Key Features

• Best practices for tool naming conventions, discoverability, and context management
• Automated evaluation framework for testing LLM tool-calling effectiveness
• Patterns for implementing streamable HTTP and stdio transport mechanisms
• Standardized error handling and pagination strategies for robust API interactions
• 0 GitHub stars
• End-to-end implementation guidance for both Python (FastMCP) and TypeScript (MCP SDK)

Use Cases

• Creating specialized workflow tools for developer productivity or data analysis
• Migrating legacy API integrations to the standardized Model Context Protocol
• Building custom bridges between internal enterprise APIs and Claude
