Klass Personal OS
Mac app that runs Claude or Codex on a schedule against your mail, calendar, and files.
What it does
Klass Personal OS is an MCP server, a connector that lets an AI assistant use it as a tool. It is installed locally as a package and runs on your machine.
From the publisher's description, Electra Index matched it to one capability: calendar management. That makes it a candidate for tasks such as plan a content calendar or schedule meetings.
Facts come from the Official MCP Registry, as declared by the publisher. Capabilities are matched automatically (low confidence) and are not a test of the tool.
