Set up banish for Gemini CLI

banish runs as an MCP server. Register it in Gemini CLI and every command it runs through banish comes back compacted, so Gemini spends far fewer tokens on verbose shell and tool output.

Prerequisites

• banish installed. See install and confirm with banish version.
• Gemini CLI, which supports MCP servers over stdio.

Register banish

Add banish to your Gemini CLI settings at ~/.gemini/settings.json (user scope) or .gemini/settings.json (project scope):

{
  "mcpServers": {
    "banish": { "command": "banish", "args": ["serve"] }
  }
}

If Gemini cannot find banish on your PATH, replace "banish" with the absolute path from which banish.

Verify

Start Gemini CLI and list its tools. banish exposes every verb in your extensions as an MCP tool - with the defaults you get 45-plus tools such as banish_gs, banish_dps, and banish_kpods. If they appear, banish is wired in.

What you get

Gemini now reads compacted output through banish. See MCP server for how verbs become tools, the benchmarks for measured savings, and set up an agent for the general flow.
