Set up banish for Windsurf

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

Prerequisites

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

Register banish

Add banish to the Windsurf MCP config at ~/.codeium/windsurf/mcp_config.json (on Windows, %USERPROFILE%\.codeium\windsurf\mcp_config.json):

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

Restart Windsurf after editing so Cascade reloads the server list. If Windsurf cannot find banish on your PATH, replace "banish" with the absolute path from which banish.

Verify

Open Cascade and check its available 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

Cascade 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.

Other agents: Gemini CLI, OpenAI Codex, Cline, GitHub Copilot.
