From v11.5.0, MCP support for Gemini-CLI is available.
Google's Gemini CLI (Command Line Interface) is a large language model that is run from the Terminal window and has access to files in the terminals current directory.
(Eastgate's summary on Gemini) Its forté is software development, and it is quite proficient at manipulating text files of various kinds. Its general knowledge (e.g. of cooking) is quite good, though it is less adept than Claude at finding good scholarly sources.
Instructions for installing Gemini-CLI may be found here: https://github.com/google-gemini/gemini-cli.
Gemini, like Claude, must launch Tinderbox when it starts up. It cannot connect to a running instance to Tinderbox. Once launched, you are free to use Tinderbox alongside Gemini.
The menu Tinderbox 11 ▸ Enable/Disable AI Integration enables and disables both Claude and Gemini. When adding Gemini to Tinderbox where Claude has been enabled, disable AI Integration and then re-enable it again to install Tinderbox/Gemini integration as well. Important: then Quit Tinderbox and allow Gemini to launch it before trying to use Gemini CLI with Tinderbox.
The built-in Hints container adds a new branch /Hints/AI/Gemini. Re-adding the Build-in Hints to an existing file will add the new container and its contents.
Gemini uses a file GEMINI.md to define the parameters of the user's project. The OS file ~/.gemini/GEMINI.md applies to all Gemini projects; each directory may also have its own GEMINI.md, which is appended to the master instructions.
