About Gemini MCP Tool
Gemini MCP Tool is a small MCP server that lets an assistant such as Claude Code call the Gemini CLI, using Gemini's large context window to analyse big files and codebases referenced with @ syntax, or to brainstorm alongside the calling model. The aim is to save the calling model's own context and tokens.
Gemini MCP Tool is listed in this index written primarily in TypeScript, with 2.3k stars on GitHub. Its latest recorded repository push was in July 2026; that is not an ASE editorial review date.
Before connecting: access and data
This record's specific permissions have not been reviewed by ASE. Read the publisher's documentation before copying setup or connecting.
- List the accounts, files and services the enabled tools can read, change or execute. Check your actual credentials and discovered tools.
- Use narrowly scoped credentials and read-only mode where supported. Review proposed writes before approving them; a generated configuration does not apply these limits for you.
- Local launch is not local-only data processing. External services receive requests, and your client may pass tool results to its model provider. Check both destinations before sharing private data.
- Keep keys and browser session files out of shared config, repositories and screenshots. Know how to disconnect the server and separately revoke its credentials or account sessions.
Add Gemini MCP Tool to your MCP client
Generated from the launch command in the project's README. Your client starts the server on demand.
