CVE-2026-0755critical · fixedCVSS 9.8

gemini-mcp-tool vulnerable to OS command injection and @file exfiltration via prompt quoting (CVE-2026-0755)

Untrusted prompt input could reach the Gemini CLI @file parser, allowing read/exfiltration of arbitrary local files (@/etc/passwd, @~/.ssh/id_rsa, @../../secret). On Windows, unquoted cmd.exe metacharacters could break out into OS command injection. Fix (1.1.6): removed the broken shell:false double-quote wrapping; added assertSafeFileReferences() to contain @file refs to the working directory; hardened Windows cmd.exe argument quoting.

Affected: >= 1.1.2Fixed in 1.1.6source →

Gemini MCP Tool

📚 View Full Documentation - Search me!, Examples, FAQ, Troubleshooting, Best Practices

This is a simple Model Context Protocol (MCP) server that allows AI assistants to interact with the Gemini CLI. It enables the AI to leverage the power of Gemini's massive token window for large analysis, especially with large files and codebases using the @ syntax for direction.

Ask gemini natural questions, through claude or Brainstorm new ideas in a party of 3!

TLDR: + ()

Goal: Use Gemini's powerful analysis capabilities directly in Claude Code to save tokens and analyze large files.

Prerequisites

🚀 Important: Gemini CLI is retired. This tool now defaults to Antigravity CLI (`agy`)

On 2026-06-18, Google retired the Gemini CLI for free, Google AI Pro, and Google AI Ultra users (and individual Gemini Code Assist / GitHub-org users). Its successor is the Antigravity CLI (agy). See Google's announcement.

From 2026-06-18 this tool selects the agy backend automatically. If you are on an affected tier, just install agy:

curl -fsSL https://antigravity.google/cli/install.sh | bash   # macOS / Linux

Then run agy once to sign in. Nothing else to change.

Enterprise / Standard-license or paid-API-key user? Your Gemini CLI access is unaffected by the retirement. To keep using it, set one env var on the MCP server:

GEMINI_MCP_BACKEND=gemini

Variable	Purpose
`GEMINI_MCP_BACKEND`	`gemini` or `agy`/`antigravity`. Unset uses the date-aware default (`agy` from 2026-06-18).
`AGY_CLI_PATH`	Full path to the `agy` binary if it isn't on the server's PATH.
`GEMINI_MCP_TIMEOUT`	Overall CLI run timeout in minutes (default 45).

The agy backend is experimental: print mode is Gemini 3.5 Flash-only, replies come from agy's stdout (transcript recovery only as a fallback), and tool execution isn't sandboxed in -p. The tool emits a notice when a requested model/sandbox can't be honored, and surfaces agy's own errors (quota, auth) verbatim. Full analysis: docs/migration/antigravity-cli.md.

Before using this tool, ensure you have:

Node.js (v16.0.0 or higher)
Google Gemini CLI installed and configured

One-Line Setup

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

For Windows users

Use -- y instead of -y:

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

Verify Installation

Type /mcp inside Claude Cod
