Gemini Research MCP Server

MCP server for AI-powered research using Gemini. Fast grounded search + comprehensive Deep Research + session management.

Tools

Tool	Description	Latency
research_web	Fast web search with citations	5-30 sec

Power User Workflow

Key insight: Gemini Deep Research runs asynchronously on Google's servers. Even if VS Code disconnects, your research continues. The resume_research tool retrieves completed work.

Features

• Auto-Clarification: research_deep asks clarifying questions for vague queries via MCP Elicitation
• MCP Tasks: Real-time progress with streaming updates
• Session Persistence: Research sessions are automatically saved and can be resumed later
• Export Formats: Export to Markdown, JSON, or professional DOCX with Table of Contents
• File Search: Search your own data alongside web using file_search_store_names
• Format Instructions: Control report structure (sections, tables, tone)
