What is gemini-mcp CLAUDE.md?

Project instructions for a server that connects Claude to Google's Gemini AI models. Gemini is Google's family of generative AI models, and an MCP server is a service that makes tools available to an AI client.

Use them when developing or testing the Gemini connection, command-line interface, logging, or tools for querying and collaborating with Gemini.

They explain the server's components, commands, configuration, and available tools so an agent can work in the project without guessing how the connection is built.

Token cost

What it costs to keep this loaded

Counted locally with the o200k_base tokenizer, which is exact for GPT models; Claude uses its own tokenizer and its counts differ. Treat this as one consistent yardstick across the catalogue rather than a bill. Prices are per million input tokens.

Model	Per session	Once invoked
Fable 5.1	$0.02566	$0.02566
Opus 5	$0.01283	$0.01283
Sonnet 5	$0.00513	$0.00513

Security

Grade A, and why

gemini-mcp CLAUDE.md scanned grade A with 0 findings against 26 rules in 11 categories — prompt injection, anti-refusal, data exfiltration, privilege escalation, supply chain, agent snooping, system-prompt leakage, SSRF and excessive agency — measured 8d ago.

A static scan of the body, not an audit. Every finding is printed with the line that produced it so you can judge whether it matters here. A mod is markdown that instructs an agent; that is exactly why what it instructs is worth reading.

Nothing flagged

None of the 26 patterns this scan looks for appear in this file: no shell pipes, no recursive deletes, no credential paths, no hidden text, no instruction-override or anti-refusal phrasing, no agent-config snooping. That is not a guarantee, it is the absence of the things that are checkable.

Gemini MCP Server Project Guide

This document provides essential information for Claude when working with this Gemini MCP server project.

Project Overview

This project is an MCP (Model Context Protocol) server that connects Claude to Google's Gemini 3 AI models. It enables bidirectional collaboration between Claude and Gemini, allowing them to work together by sharing capabilities and agent tools.

Version: 0.8.1 Package: @rlabs-inc/gemini-mcp MCP Registry: io.github.rlabs-inc/gemini-mcp

Key Components

src/index.ts: Dual-mode entry point (MCP server or CLI)
src/server.ts: MCP server implementation
src/cli/: CLI implementation with themes and commands
src/gemini-client.ts: Client for Google's Generative AI API (includes thinking levels, image/video generation)
src/utils/logger.ts: Logging utilities with configurable verbosity
src/tools/*.ts: Various tool implementations for integration with Claude Code

Tools Implemented

Query (query.ts): Direct queries to Gemini with thinking level control
- thinkingLevel: minimal, low, medium, high
Brainstorm (brainstorm.ts): Collaborative brainstorming between Claude and Gemini
Analyze (analyze.ts): Code and text analysis using Gemini
Summarize (summarize.ts): Content summarization at different detail levels
Image Gen (image-gen.ts):
- gemini-generate-image: Generate images with Nano Banana Pro
  - Up to 4K resolution (1K, 2K, 4K)
  - 10 aspect ratios (1:1, 2:3, 3:2, 3:4, 4:3, 4:5, 5:4, 9:16, 16:9, 21:9)
  - Google Search grounding for real-world accuracy
  - Returns base64 that Claude can SEE!
- gemini-image-prompt: Generate prompts for other image tools (legacy)
Image Edit (image-edit.ts): Multi-turn conversational image editing
- gemini-start-image-edit: Start an editing session
- gemini-continue-image-edit: Continue refining with follow-up prompts
- gemini-end-image-edit: Close a session
- gemini-list-image-sessions: List active sessions

Hashed on every crawl. A supply-chain change to an agent config is a question of when, not whether, so the history is kept rather than the latest state alone.
