2. 02

   Save the file and restart Claude Desktop.

3. 03

   TokenLab Model Explorer is surfaced in the attachment menu, where you pick it as context. It is context to attach, not an action to run.

4. 04

   If it does not appear, check that TokenLab MCP Server is connected and that you are looking at its resources rather than its tools.

Settings → Developer → Edit Config opens this file. Restart the app after saving. Claude Desktop docs
