One MCP server for every app you use.

The Model Context Protocol (MCP) is the open standard AI clients use to call tools. An MCP server exposes those tools: "create a customer in Stripe", "list open issues in GitHub", "send a message in Slack". A local server runs on your machine; a remote server runs at a URL, which is what 0n3 is. You connect your apps once; every AI you install 0n3 into gets the same tools, with your own connections, and never sees a key.
