Haruspex Gemini CLI Extension

Live 0–100 stock scoring across 20+ dimensions, available as a Gemini CLI extension. Wraps the @haruspex-guru/mcp-server-gemini npm package — the Gemini-tuned distribution of the Haruspex MCP server (sister to @haruspex-guru/mcp-server which serves Claude Desktop / Base44 / Cursor).

Install

gemini extensions install https://github.com/Haruspex-guru/haruspex-gemini-extension

For local development from a clone of this directory:

gemini extensions install --path .

On install, Gemini will prompt for your Haruspex API Key (hrspx_*). Get one at https://haruspex.guru/haruspex-api.

What ships

• 4 skills: score-lookup, dimension-compare, supply-chain-risk, thesis-builder (auto-loaded from skills/)
• 3 slash commands: /haruspex-score, /haruspex-compare, /haruspex-watchlist (from commands/)
• An MCP server config that spawns the Haruspex MCP via npx on demand
• A GEMINI.md that teaches the agent how to call everything
