Connect Claude, ChatGPT, Codex and Cursor over MCP
The same search, calendar and workflow tools, on your account, from the assistant you already use.
Model Context Protocol is a socket, not a new product. Point Claude, ChatGPT, Codex or Cursor at Kaer and the assistant can search the web, read the calendar and run a workflow as you.
Metered tools bill at the same rates as they do inside Kaer. Read-only tools stay unmetered.
Keys are capped, revocable, and scoped. The walkthrough lives on the blog because that is where the config blocks belong.
