💻 Usage Examples

Usage With Claude Desktop

The server must be running in order for Claude Desktop to detect searchcraft-mcp-server's tools.

searchcraft-mcp-server uses StreamableHTTPServerTransport, so in order to connect it to Claude Desktop, we use mcp-remote ↗︎.

In your claude desktop config file, add the following:

claude_desktop_config.json

{
  "mcpServers": {
    "searchcraft": {
      "command": "npx",
      "args": [
        "mcp-remote",
        "http://localhost:<MY-PORT-FROM-ENV>/mcp"
      ]
    }
  }
}

The claude desktop config file can be found at /Users/[My Workspace]]/Library/Application Support/Claude/claude_desktop_config.json. If no file exists here you can create it.

Claude desktop config example

Claude Desktop Node Version

⚠️ Important Note

We have experienced that when Claude Desktop runs the command to connect to the MCP server, it can sometimes choose an older version of Node. If older versions of node are installed on your system, this can lead to issues. Ensure that your default Node version on your system is high enough to properly run the server.
