Agents

Your agents work in your cloud, not a copy of it.

calternal gives AI the same documents you see, through the same API you use. No sync to a third party, no screenshots pasted into a chat window.

  • A container of your own

    Each User gets a private, rootless container with Claude Code, Codex and the calternal CLI installed. It starts when you need it and stops when idle.

  • Your subscription, your keys

    Sign in to the agents you already pay for. Local features such as semantic search run on the server with no API key.

  • Edits you can see

    An agent edits your Notes as a live collaborator, with its own cursor and colour. Each agent turn is one undo step.

  • Scoped, revocable access

    Agents reach your data only through the API with a scoped token. They never get a mount of your Home.

  • MCP, built in

    Connect any MCP client to your instance with an App Password. Read-only or full, your choice per password.

  • Discoverable

    Every instance publishes llms.txt, an Agent Skill and an MCP Server Card, so an agent can learn how to use it on its own.

Connect Claude Code in one line.

Make an App Password in Settings → Apps, then add your instance as a remote MCP server.

claude mcp add --transport http calternal \
  "https://<your-instance>/mcp" \
  --header "Authorization: Bearer $CALTERNAL_MCP_TOKEN"
