One-Sentence Takeaway:
Rails 8 empowers developers by simplifying complexity, promoting self-reliance, and enabling deployment without external dependencies.
MCP (Model Context Protocol) basically enables LLM's (AI) to gain access to additional sources of data and interact with API's, file systems, databases and more.
🧵
MCP is like a universal translator between AI assistants and your everyday apps.
Without MCP: AI is limited to what it learned in training (like using an old encyclopedia).
With MCP: AI can access live information and perform actions in your apps.
User: Asks questions or makes requests in plain language.
MCP Client: The chat interface where you type your request.
AI Model: Understands what you're asking for.
MCP Servers: Special connectors for each service (Gmail, Drive, etc.).
