MCP SERVERSend a prompt, a file or a whole directory to Gemini for a second opinion, and get the review back in the same conversation.
LABSCO SUMMARY
Your primary assistant is confident whether or not it is right, and this puts an independent reader on the same files. Context is the reason to pick Gemini over its siblings here — the @ file syntax feeds it whole directories, so a review can cover more than the diff. Edits come back as OLD/NEW blocks rather than prose, which is what lets the fix be applied without copy-paste.
The Gemini server out of the Ask LLM family: it hands a prompt to the Gemini CLI on your machine and returns the answer to whichever assistant asked. It now ships as @ask-llm/gemini-mcp; the older ask-gemini-mcp package name is deprecated and the executable name is unchanged.

Add it over stdio as npx -y @ask-llm/gemini-mcp. One dated fact to check before building on it: from 2026-06-18 Google restricts the Gemini CLI to Gemini Code Assist Standard and Enterprise seats, and free, AI Pro and Ultra accounts lose access — the package still installs, but a non-enterprise account gets guidance in place of output. The repo names ask-antigravity, ask-codex, ask-claude and ask-ollama as the routes for those accounts.
One command — claude mcp add --scope user gemini -- npx -y @ask-llm/gemini-mcp
USE CASES
Send the changed file for an independent read, then apply the findings your own assistant agrees with.
Hand over the design document and ask for alternatives and trade-offs rather than approval.
Ask for the edit as structured OLD/NEW blocks so your assistant can apply them straight to the file.
Pull the remaining chunks of the cached response instead of asking the question again.
Read the session's token totals and call counts, broken down by provider and model.
Counted once with only startup setup. Other versions, modes or optional credentials may expose a different list.
ask-geminiSend a prompt to Gemini CLI (defaults to gemini-3.1-pro-preview with automatic Flash fallback on quota errors). Use for code review, second opinions, analysis, and AI-to-AI collaboration. Do not override the model parameter unless the user explicitly asks. Returns both human-readable text and a structured response (provider, model, sessionId, usage) via outputSchema.
ask-gemini-editSend a code edit request to Gemini CLI and get structured OLD/NEW edit blocks back. Gemini analyzes the files and returns precise, applicable code changes. Use this when you want Gemini to suggest specific code modifications rather than just analysis.
fetch-chunkRetrieves cached chunks from a changeMode response. Use this to get subsequent chunks after receiving a partial changeMode response.
get-usage-statsGet the current MCP server's session usage stats: total LLM calls, token totals (input/output/thinking/cached), wall time, and breakdowns per provider and per model. No data leaves your machine — counts are tracked in-memory for the lifetime of the server process. Returns both human-readable markdown and a structured JSON snapshot via outputSchema.
