OpenAI Makes GPT-5.6 Luna Free with Unlimited ChatGPT Text Chats
OpenAI is replacing GPT-5.5 Instant with GPT-5.6 Luna for Free and Go users, then removing text-chat limits and adding a Think button for harder questions.
Model Context Protocol, abbreviated MCP, is an open protocol for connecting AI applications with external tools, data sources, and reusable context through a consistent interface. An MCP server can expose resources or actions, while a compatible client decides when and how the model may access them. Standardization reduces the need for a separate custom integration for every combination of assistant and service. The protocol does not remove security responsibilities: implementations still need authentication, narrow permissions, input validation, user approval for sensitive actions, and clear handling of untrusted content. Organizations should evaluate each server, log tool use, protect credentials, and restrict access according to the task rather than granting broad authority by default.
