ask_geminiLABSCO SUMMARY
A second model as a tool, with search already attached.
The value is not the wrapper but what it wraps: a Gemini call that has Google Search and URL reading turned on, so one question can pull in pages your main assistant never fetched. It is one tool with one required parameter, and the API bill is yours.
What it is
A Deno server exposing a single tool. The prompt goes to Gemini with the googleSearch and urlContext tools enabled, so the model can look things up and read any URLs you include in the text before it answers.
What you get
- One answer to a free-text question, with the web searched automatically for current information —
ask_gemini - URLs written into the prompt read and analysed as part of that same call, with no separate fetch step
- Which model answers, set by you through
GEMINI_MODEL
Requirements
A Google Gemini API key in GEMINI_API_KEY and a model name in GEMINI_MODEL. Deno v1.40+. Runs straight from JSR: the client launches deno with --allow-net, --allow-env and jsr:@cong/gemini-mcp. Both variables must be set in the same shell that launches the server — the project calls this out because it is the usual cause of a failed start.
Setup effort
One command plus a key — deno run --allow-net --allow-env jsr:@cong/gemini-mcp, then supply credentials
USE CASES
01
Getting a second opinion mid-conversation
Hand the same question to a different model and compare what comes back before committing to an answer.
02
Answering something newer than the model's training
Ask the question plainly; the search tool is already on, so current information is fetched rather than recalled.
03
Summarising a page without a separate fetch tool
Paste the URL into the question text and let the same call read and analyse it.
