Build with Claude and MCP

The Model Context Protocol (MCP) is a standard that allows AI models like Claude to securely connect to external tools, services, and data sources. In AI Architect, MCP is what enables Claude to communicate with the Atsign MCP server so it can generate blueprints, fetch information, and perform actions based on your instructions.

By connecting Claude to the AI Architect MCP server, you give it controlled access to the tools it needs to create your blueprint directly on the canvas.
