MCP Server Development

mcp-server-patterns is a practical guide for MCP Server Development with the Node/TypeScript SDK. Learn when to use tools, resources, prompts, Zod validation, and stdio vs Streamable HTTP, with current API notes for safer implementation and debugging.

mcp-builder is a practical guide for planning, building, and evaluating MCP servers for external APIs and services. It helps developers choose tool scope, naming, transport, Python or Node implementation patterns, and evaluation workflows so agents can use the server reliably.

Documentation lookup for the browser-use Python library. The open-source skill helps with install, setup, Agent and Browser code, model env vars, tools, MCP integrations, monitoring, and legacy Actor API guidance.

mcp-builder is a practical guide for MCP Server Development, helping you design high-quality servers that let LLMs use external services through clear, reliable tools. It covers architecture choices, tool boundaries, schema quality, evaluation thinking, and when to reuse Microsoft MCP services instead of building custom.

Use x-twitter-scraper to retrieve X (Twitter) data and confirmation-gated actions through Xquik. It supports tweet search, user lookup, follower extraction, media download, monitors, webhooks, MCP, and write actions. Best for web scraping-style research with an API key, not X login secrets.

reunion is a local-first skill for building memorial chat agents from memories, chat logs, diaries, photos, and oral recollections, with Memory and Persona analysis, CLI use, and MCP server support for Agent Orchestration.

swift-nio is a skill for SwiftNIO backend development, covering servers, clients, pipelines, buffers, codecs, and event-loop-safe async code. Use it for swift-nio usage questions, protocol parsing, TCP/UDP services, NIOAsyncChannel integration, and debugging blocking work on an EventLoop. It is a practical swift-nio guide for correct architecture and implementation.

The copilot-sdk skill helps you build applications that programmatically use GitHub Copilot through the Copilot SDK. It fits API Development and app integrations in Node.js, Python, Go, and .NET, with session management, streaming, tools, hooks, MCP servers, and reusable agent workflows. Requires the GitHub Copilot CLI, and a subscription unless you use BYOK.
