What this does
gemini-mcp exposes a set of tools to Claude over the Model Context Protocol. After you add it to claude_desktop_config.json (snippet above) and restart Claude Desktop, those tools become callable inside any conversation.
Requirements
This server needs the following environment variables to be set before it can run:
GEMINI_API_KEY GEMINI_IMAGE_MODEL GEMINI_OUTPUT_DIR GEMINI_INPUT_DIR GEMINI_UPLOAD_DIR GEMINI_REFERENCE_DIR GEMINI_TIMEOUT_MS GEMINI_HEARTBEAT_MS GEMINI_CHAIN_RETRY_MS GEMINI_DEBUG GEMINI_RATE_CARD
Set these via the env object in your MCP config (see claude_desktop_config.json snippet above).
