I tried to install OpenRouter MCP Server using Cline Extension in VSCode Insiders as MCP Client. I got my reference from Smithery (/@mcpserver/openrouterai).

This is my cline_mcp_settings.json located at "C:\Users\takan\AppData\Roaming\Code\User\globalStorage\saoudrizwan.claude-dev\settings":

{
  "mcpServers": {
    "openrouterai": {
      "command": "npx",
      "args": ["-y", "@smithery/cli@latest", "run", "@mcpserver/openrouterai"],
      "env": {
        "OPENROUTER_API_KEY": "xxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxx",
        "OPENROUTER_DEFAULT_MODEL": "google/gemini-2.0-pro-exp-02-05:free"
      }
    }
  }
}

I got "spawn npx ENOENT spawn npx ENOENT" after Cline automatically connected with the server after I saved the file.

I found a discussion similar to my problem in a GitHub Issue "Connect MCP Servers error"spawn npx enoent" #1948". However, they are just posting their .json file without any explanation. So here is my own solution:

1. Make sure you have Node.js installed (I'm using Node Version Manager).
2. Install "OpenRouter MCP Server" globally. I added "-g" to install globally and run it in a powershell.

npm install -g @mcpservers/openrouterai

3. Edit the cline_mcp_settings.json which I found at:

C:\Users\Username\AppData\Roaming\Code - Insiders\User\globalStorage\saoudrizwan.claude-dev\settings

4. Change the "command" into where my node.exe is located.

"command": "C:\Program Files\nodejs\node.exe".

5. Change the "args" into where my @mcpservers/openrouterai is located.

"args": [ "C:\Program Files\nodejs\node_modules\@mcpservers\openrouterai\dist\index.js" ],
