Gemini CLI MCP Tool Integration Issue - Command Spawn Error (ENOENT)

I'm experiencing errors when trying to use the Gemini-CLI MCP (Model Context Protocol) integrated with Claude Code. Despite the configuration appearing correct, Gemini commands are not working properly.

Gemini-CLI MCP Configuration

{
  "mcpServers": {
    "gemini-cli": {
      "type": "stdio",
      "command": "npx",
      "args": ["-y", "gemini-mcp-tool"],
      "env": {
        "GOOGLE_API_KEY": "[API_KEY_OCULTA]"
      }
    }
  }
}

Command Used to Add MCP

claude mcp add gemini-cli -- npx -y gemini-mcp-tool

Current Status

• ✅ MCP Server configured in project
• ✅ Google API Key configured in environment
• ✅ Package gemini-mcp-tool accessible via npx
• ❌ Gemini commands returning errors

Failed Commands Tested

• /gemini-cli:ask-gemini (MCP) ola gemini
• /gemini-cli:Help (MCP)
• /gemini-cli:ping (MCP)
• /gemini-cli:timeout-test (MCP)

Additional Context

• MCP is configured both in the current project and user home directory
• API key is present in configuration but not working properly
• Other Claude Code tools work normally

Error Logs or Messages

Error executing ask-gemini: Failed to spawn command: spawn gemini ENOENT

Error Analysis

• ENOENT: "Error: No such file or directory" - indicates that the gemini command was not found
• System is trying to execute gemini directly instead of using npx -y gemini-mcp-tool
• Possible issue with MCP configuration or command parsing

Objective

Identify and resolve the issue preventing proper functioning of the Gemini-CLI MCP to be able to use Gemini functionalities integrated with Claude Code.

For anyone experiencing issues making it work through WSL for claude desktop, here is summary of my troubleshooting session with claude.

P.S. am very not used to windows development flow, so there might be something obvious to someone
