Imagine handing an AI agent a complex task—like building an entire Python course—and simply walking away, letting it run indefinitely until you intervene. Ralph Mode, built on Deep Agents from LangChain, makes this possible by looping the agent with fresh filesystem-backed context each iteration.[5] This approach transforms AI from one-shot responders into persistent workers, using the filesystem as infinite memory. In this comprehensive guide, we’ll dive deep into Ralph Mode’s mechanics, its integration with Deep Agents, real-world examples, and how you can harness it for your own projects. ...

Introduction The Model Context Protocol (MCP) is rapidly becoming a foundational layer for connecting AI models to external tools, data sources, and services in a standardized way. As more powerful capabilities are exposed to models—querying databases, sending emails, acting in SaaS systems—authorization becomes a central concern. This article walks through: What MCP is and how resources fit into its design What link resources are and why they matter How link resources are typically used to drive authorization flows Example patterns for building MCP servers that handle auth securely Best practices and common pitfalls The goal is to give you a solid mental model for how MCP authorization with link resources works in practice, so you can design safer, more capable integrations. ...
