Save this as ~/.claude/looker-delete-tools.yaml%USERPROFILE%\.claude\looker-delete-tools.yaml. The .claude folder already exists if you've set up the connector; create the file inside it with any plain text editor. Copy the whole block exactly as it is, including the last section that starts with kind: toolset.

Open the config file holding your "looker-toolbox" entry (~/.claude.json%USERPROFILE%\.claude.jsonclaude_desktop_config.json, via Settings → Developer → Edit Config) and add a --config flag pointing at the tools file, right after --prebuilt looker. Nothing else in the entry changes, you just extend the "args" list:

"args": [
  "--stdio", "--prebuilt", "looker",
  "--config", "/Users/your-username/.claude/looker-delete-tools.yaml"
]

"args": [
  "--stdio", "--prebuilt", "looker",
  "--config", "C:\\Users\\your-username\\.claude\\looker-delete-tools.yaml"
]

Save the file. Don't restart Claude yet, the next step checks your work first.

Before restarting, confirm the tools file parses by running the connector by hand. It should print a line saying it initialized 23 tools and 3 toolsets, then wait for input (press Ctrl+C to stop it). If it prints an error about the config file instead, the path or the YAML needs fixing:

/opt/homebrew/bin/toolbox --stdio --prebuilt looker --config ~/.claude/looker-delete-tools.yaml

& "$env:LOCALAPPDATA\mcp-toolbox\toolbox.exe" --stdio --prebuilt looker --config "$env:USERPROFILE\.claude\looker-delete-tools.yaml"

Once that looks right, restart any open Claude Code sessionfully quit and reopen Claude Desktop for the change to take effect. Deleting is just another MCP tool at this point, so it works the same in both Claude apps.

Ask normally, the same way you'd ask for a new dashboard. A few examples:

• Delete the dashboard called "Old Ops Overview".
• Remove the "Tickets by priority" tile from the Ops Overview dashboard.
• Delete the Look I made yesterday about reboot counts.

Claude will look the object up, confirm the exact name and id with you, then handle the rest itself. If it says it has no delete tools, see Troubleshooting below.

If you'd rather go back to a connector that can't delete anything, open the same config file from Step 4 and remove the --config flag and the path that follows it from the "args" list, so it ends with "--prebuilt", "looker" again. Restart your Claude Code sessionQuit and reopen Claude Desktop and the delete tools are gone. You can leave the YAML file where it is or delete it, nothing reads it without the flag.
