Use TstoneLab from Claude Desktop (MCP)

What you can do

Ask about your Touchstone files in plain language

Once it's set up, Claude Desktop can use TstoneLab to read and analyze .sNp files on your computer — you don't even need to have the TstoneLab app open. Claude Desktop starts TstoneLab's local MCP helper when it needs it. A few examples:

Set it up

Turn it on in Claude Desktop

TstoneLab offers this through MCP, an option you switch on in your AI assistant. Here's the core step — adding TstoneLab to Claude Desktop's configuration:

1. Open the config file
   In Claude Desktop, open Settings → Developer and click Edit Config. This creates the file claude_desktop_config.json (if it doesn't exist yet) and opens its folder. Open that file in a text editor.
2. Add TstoneLab and save
   If the file already has an "mcpServers" section, add just the "TstoneLab" entry inside it — don't create a second one.
   claude_desktop_config.json Copy

   {
     "mcpServers": {
       "TstoneLab": {
         "command": "tstonelab-mcp.exe"
       }
     }
   }

3. Restart Claude Desktop completely
   Closing the window isn't enough — Claude Desktop keeps running in the background. You must fully quit it from the system tray: find the Claude icon in the notification area (the ^ arrow at the bottom-right of the taskbar), right-click it, and choose Quit. Then reopen Claude Desktop so it loads the new config.

Please find and edit Claude Desktop's configuration file
(claude_desktop_config.json) to add an MCP server named "TstoneLab".

Locate the file first:
- Normally it is at %APPDATA%\Claude\claude_desktop_config.json.
- If Claude Desktop was installed from the Microsoft Store, it instead uses
  %LOCALAPPDATA%\Packages\Claude_*\LocalCache\Roaming\Claude\claude_desktop_config.json.
- Edit whichever one already exists. If neither exists, create the %APPDATA% one.

The entry to add is exactly:

  "TstoneLab": {
    "command": "tstonelab-mcp.exe"
  }

Rules you must follow:
1. If the file already exists, first read it and show me its current contents.
   Do NOT delete or change any other server entries under "mcpServers"; only
   merge in the "TstoneLab" key. If there is no "mcpServers" key, create it.
   When creating a new file, use:
   {
     "mcpServers": {
       "TstoneLab": { "command": "tstonelab-mcp.exe" }
     }
   }
2. If a "TstoneLab" entry already exists, show me the current value vs. the new
   value and ask before overwriting it.
3. Before modifying, back up the original to the same path with a .bak extension.
4. After saving, print the full final file contents and verify the JSON is valid
   (braces and commas correct).
5. Finally, remind me to fully quit Claude Desktop (including the tray icon) and
   restart it for the change to take effect.

TstoneLab runs as a local tool on your computer, so it works with assistants that can launch a program on your machine — not with web-only ones.
