Guide for building high-quality MCP servers that let LLMs interact with external APIs via workflow-focused tools, SDKs, validation, and error handling in Python or TypeScript.

This guide details the process of building Model Context Protocol (MCP) servers. These servers are crucial for enabling Large Language Models (LLMs) to interact with external APIs and services, facilitating complex, real-world task completion. It provides comprehensive coverage on architectural planning, choosing appropriate languages (Python, TypeScript, C#), and selecting transport mechanisms (HTTP, stdio) for robust integration within enterprise ecosystems like Azure and Foundry.

This skill guides the integration of Model Context Protocol (MCP) into Claude Code plugins. It enables plugins to securely connect to external services, APIs, databases, and file systems by exposing capabilities as structured tools. Supports multiple connection methods (stdio, SSE, HTTP, WebSocket) and handles complex authentication flows like OAuth and token-based access for robust tool access.

This skill outlines a comprehensive, low-downtime process for migrating APIs between different versions, frameworks, or platforms. It guides the implementation of advanced architectural patterns like the Strangler Fig pattern, traffic shadowing, and canary deployments. Use this when upgrading a monolithic API to microservices or transitioning between incompatible API versions.

Automates migration guide creation by providing step-by-step documentation patterns, best practices, and validated snippets for APIs, user guides, and architecture docs.

A comprehensive guide and expertise source for developing robust, high-performance Minecraft server plugins using Bukkit, Spigot, and Paper APIs. Covers advanced topics including event handling, NMS internals, performance profiling, architecture design (SOLID), and ecosystem integration (Redis, Docker). Ideal for complex, production-grade plugin development.

Automatically generates robust, schema-compliant mock API servers directly from OpenAPI specifications. This tool supports advanced testing features, including stateful CRUD operations, Faker-driven dynamic data generation, configurable latency simulation, and detailed request recording for contract testing. Ideal for frontend parallel development and isolated integration testing.

A comprehensive guide for developing custom external web service APIs for the Moodle Learning Management System (LMS). It covers Moodle's required API framework, coding standards, and the essential three-method pattern (execute_parameters, execute, execute_returns) necessary for integrating custom functionality, such as course management, quiz operations, and reporting, with external applications.

Catalogs proven n8n workflow architectural patterns for webhook handling, APIs, database syncing, AI agents, and scheduled tasks, helping teams pick structures, plan nodes, and handle triggers, data paths, and error strategies during workflow design and troubleshooting.

This skill provides comprehensive guidance for building scalable, maintainable, and production-ready backend applications using Node.js. It covers modern architectural patterns, best practices, and implementation details for REST APIs, GraphQL servers, microservices, authentication, real-time WebSockets, and complex database integrations (SQL/NoSQL).

This comprehensive guide helps developers make critical architectural decisions in modern Node.js development. It covers framework selection (Fastify, Hono, Express), implementing layered architecture, mastering async patterns, robust error handling, and essential security protocols. The focus is on teaching architectural thinking and problem-solving skills, ensuring the development of scalable, high-performance, and maintainable backend APIs.

This skill provides comprehensive patterns for creating, maintaining, and validating OpenAPI 3.1 specifications for RESTful APIs. Use it for design-first API contract definition, generating specs from existing code, creating detailed API documentation, validating implementation conformance against the contract, and generating client SDKs. It ensures consistency across the entire API lifecycle.
