Primitives & Execution

Universal Context Sockets

The Model Context Protocol (MCP) is an open-source standard created by Anthropic to eliminate custom integrations. It allows you to build an "MCP Server" once (e.g., for YourSQL database) and connect it to any AI assistant (Claude, VS Code, etc.) using a standardized JSON-RPC protocol over STDIO or Streamable HTTP.

The Three MCP Primitives

• Resources: Static data sources like README files or database logs (Read-only).
• Prompts: Templated instructions (e.g., "Review this PR").
• Tools: Executable functions that can mutate state (e.g., "Write to file").
