How do I connect Claude Desktop to Tandem?

Question

I installed Tandem and it's running, but how do I connect Claude Desktop so it can use the MCP tools?

Answer

Add this to your Claude Desktop config file:

macOS: ~/Library/Application Support/Claude/claude_desktop_config.json

{
  "mcpServers": {
    "tandem": {
      "command": "node",
      "args": ["/path/to/tandem-browser/dist/mcp/server.js"]
    }
  }
}

Replace /path/to/tandem-browser with the actual path where you cloned the repo.

Make sure Tandem is running (npm start) before you start Claude Desktop. Once connected, Claude will have access to all 236 MCP tools.

The same config works for Claude Code (put it in .mcp.json in your project root or ~/.claude/settings.json) and any other MCP-compatible client like Cursor or Windsurf.
