Setting up the Studio 3T Desktop IDE’s local MCP server

• Use ⌘ Shift P (macOS) or Ctrl Shift P (Windows/Linux) to open the Command Palette
• Search for MCP: Add Server and select it
• Select HTTP
• Paste http://127.0.0.1:27117/mcp and hit Enter
• Type studio3t when asked for a Server ID, then hit Enter.
• Choose whether to add this server globally or only for the current workspace.

After having set these options, your mcp.json will look like this:

{
  "servers": {
    "studio3t": {
      "type": "http",
      "url": "http://127.0.0.1:27117/mcp"
    }
  }
}

At this point, open the chat panel with ⌥⌘B or ⌃⌘ or Ctrl+Alt+B (Windows/Linux), or open the Command Palette and select Chat: Focus on Chat View.

Switch to Agent mode, then type #list_connections to confirm the Studio 3T tools are available.

For more information, see the VS Code official MCP documentation.

• Open Cursor → Settings → Cursor Settings.
• Go to the MCP tab.
• Click + Add new global MCP server.

Enter the following configuration and save:

{
  "mcpServers": {
    "studio3t": {
      "url": "http://127.0.0.1:27117/mcp"
    }
  }
}

For more information, see the Cursor official MCP documentation.

Open your terminal and run the command below to add the MCP server for all Claude Code sessions (not just the current directory):

claude mcp add --transport http studio3t http://127.0.0.1:27117/mcp --scope user

This adds the server to ~/.claude/settings.json. You can also edit that file directly:

{
  "mcpServers": {
    "studio3t": {
      "type": "http",
      "url": "http://127.0.0.1:27117/mcp"
    }
  }
}

Useful commands for managing your MCP configuration:

For more information, see the Anthropic official MCP documentation.

• In VS Code, open the Cline sidebar and click the MCP Servers icon.
• Click Edit MCP Settings.
• Add the following entry to the config file:

{
  "mcpServers": {
    "studio3t": {
      "type": "streamableHttp",
      "url": "http://127.0.0.1:27117/mcp"
    }
  }
}

Save the file. Cline will automatically connect to the server.

For more information, see the Cline official MCP documentation.

Edit ~/.gemini/settings.json and add:

{
  "mcpServers": {
    "studio3t": {
      "httpUrl": "http://127.0.0.1:27117/mcp"
    }
  }
}

For more information, see the Gemini CLI documentation.

For any other MCP-compatible client, add the Studio 3T server using this configuration (check your client’s docs for the exact config file location):

{
  "mcpServers": {
    "studio3t": {
      "httpUrl": "http://127.0.0.1:27117/mcp"
    }
  }
}

Once configured, restart or refresh your client. You should see a successful connection and the Studio 3T tools listed. If the connection fails or no tools appear, double-check that the MCP server is enabled in Studio 3T (Settings / Preferences → External Tools), and that the port in your config matches the one set there.
