MCP
Model Context Protocol: an open standard that lets AI assistants plug into outside tools and data through one shared kind of connection.
Also called Model Context Protocol.
Before MCP, every AI tool needed its own glue for every service. Now a service builds one MCP server, and any assistant that speaks MCP can plug into it. Anthropic introduced it in late 2024, and it has spread well beyond Claude since.
A server offers tools (things the AI can do) and resources (things it can read). The assistant decides when to use them.
Base44 runs its own MCP server for creating and managing backend projects, and App MCP lets assistants work with a published app's data.
I use Higgsfield's MCP every day for the images and video in my content pipeline. Once it's connected, I just ask.
One rule, though. An MCP server acts on your behalf, so only connect ones you trust, and read the permissions before you click allow.
