Gemini MCP Wrapper

MCP wrapper for Gemini CLI tool with stderr logging support for Claude Code.

Installation

Using Claude Code CLI (easiest):

claude mcp add gemini-cli --scope user -- npx -y gemini-mcp-wrapper

Or install globally:

npm install -g gemini-mcp-wrapper

Then add to ~/.claude/mcp.json:

{
  "mcpServers": {
    "gemini-cli": {
      "command": "gemini-mcp-wrapper",
      "args": []
    }
  }
}

Prerequisites

You need both the Gemini CLI and the MCP tool:

# Install Gemini CLI (official Google tool)
npm install -g @google/gemini-cli

# Install gemini-mcp-tool (MCP server for Claude Code)
npm install -g gemini-mcp-tool

# Authenticate with Gemini
gemini auth

What it does

This wrapper:

• Runs gemini-mcp-tool via npx
• Redirects stderr to ~/gemini-mcp.log for debugging
• Keeps stdout clean for JSON-RPC communication with Claude Code

Debugging

Check logs if you encounter issues:

tail -f ~/gemini-mcp.log
