gemini_chatLABSCO SUMMARY
A second opinion from Gemini, on the credentials your CLI already holds.
Because it shells out to the Gemini CLI, there is no separate API key to manage: whatever your CLI is authorised to do, the server can do. Three tools, all of them straight passthrough.
What it is
A server that wraps the Gemini CLI: chat, generation with temperature control, and the list of available models.
What you get
- A message sent to Gemini and its reply returned, with the model selectable and gemini-pro as the default (gemini_chat)
- Content generated from a prompt, with a model and a temperature you choose (gemini_generate)
- The Gemini models your CLI credentials can reach (gemini_list_models)
Requirements
Node.js 18 or newer, and the Gemini CLI installed, credentialed and on your PATH. If the gemini command does not run in your shell, neither does the server.
Setup effort
Build from source — git clone https://github.com/blesscat/gemini-cli-mcp
USE CASES
01
Getting a second model's answer without switching apps
Send the question to Gemini and read the reply in the conversation you are already in.
02
Generating a draft at a temperature you control
Set the temperature explicitly rather than accepting whatever the default is.
03
Checking which Gemini models you actually have access to
List them from your own credentials instead of going by the documentation.
04
Comparing two models on the same prompt
Run the prompt through Gemini and set it against the answer your main assistant gave.
3 tools
Listed in project docs. Your client may show a different list.
