Fast web research with Gemini grounding. Returns answer with citations in seconds.

Uses a fixed high thinking level for higher-quality grounded answers.

Use for: quick lookups, fact-checking, current events, documentation, "what is", "how to", real-time information, news, API references, error messages.

Run the default Deep Research agent with optional File Search and MCP tools.

Resume an interrupted or in-progress research_deep session.

Use when a research_deep call was cut short (client disconnect, transport error, cancellation) or when you want to check whether a long-running session has since completed on Gemini's servers.

Because research_deep persists its session at the start, the research continues on Gemini's side even when the MCP client goes away — this tool retrieves the result once it's ready.

Call with no arguments to list recoverable sessions. Call with an interaction_id (returned by the original research_deep call or by list_research_sessions) to check a specific session's status; if it has completed, the full report is returned. Hand the result off to export_research_session(format="docx") to save the report to disk.

Save (export, download, archive) a completed research session to a file on disk — Word (.docx), Markdown (.md), or JSON. Use this to recover your report after a research_deep run completes or is interrupted, and to convert reports into a shareable Word document.

Disk-first contract. The file is always written to disk, and the absolute path is returned on the first line of the response as Saved to: <path>. When output_path is omitted the file lands in GEMINI_RESEARCH_EXPORT_DIR (default ~/.gemini-research/exports/). An EmbeddedResource is still attached so GUI hosts can expose their native "Save As" affordance.

Similar to Google's Deep Research export feature, the DOCX output is a professional Word document suitable for sharing, archiving, or further editing.

Supported formats:

• docx: Word document with headings, lists, and table of contents

• markdown: Clean .md file with full report and citations

• json: Machine-readable, all metadata preserved

Typical recovery flow:

1. research_deep(...) completes (or is resumed via resume_research).

2. export_research_session(format="docx") — no other arguments needed; the path on disk is returned in the response text.

Search for tools using natural language.

Returns matching tool definitions ranked by relevance, in the same format as list_tools.

Call a tool by name with the given arguments.

Use this to execute tools discovered via search_tools.
