# Gemini n8n Kit > 🚀 **The ultimate toolkit for orchestrating n8n workflows with Gemini CLI (Antigravity).** This repository provides specialized **Skills** and **MCP Configurations** to turn your Gemini CLI into an expert n8n developer. It is inspired by the excellent work done for Claude by `czlonkowski`, but purely re-engineered for the Gemini ecosystem. ## 📦 What's Inside? ### 1. n8n Expert Skill (`/skills/n8n-expert`) A native Gemini Skill that teaches the agent: * **Syntax Mastery:** No more broken `{{ $json... }}` expressions. * **Code Node Pro:** Generates perfect JavaScript/Python for data transformation. * **Workflow Patterns:** Knows how to build resilient webhooks, API integrations, and AI Agents. * **Validation:** Auto-detects common mistakes before you even run the workflow. ### 2. MCP Configuration (`/mcp-config`) Plug-and-play configurations to connect Gemini CLI to your local or remote n8n instance via the Model Context Protocol (MCP). ## 🚀 Installation ### Prerequisites * **Gemini CLI** (Antigravity) installed. * **n8n** instance running (local or cloud). * **Supergateway** (optional, but recommended for easy HTTP tunneling). ### Step 1: Install the Skill You can install the skill directly from this repository locally: ```bash gemini skills install ./skills/n8n-expert --scope user ``` ### Step 2: Connect n8n (MCP) Connect your n8n instance so Gemini can "see" and "control" your workflows. This kit is now optimized for the **official n8n MCP protocol**. **Option A: Using Standard SSE (Recommended)** This is the official transport protocol for the n8n MCP Client. ```bash gemini mcp add n8n-mcp "http://localhost:3000/mcp" --header "Authorization: Bearer <YOUR_TOKEN>" --trust ``` **Option B: Using npx (Quick Local Setup)** If you haven't deployed the server yet: ```bash gemini mcp add n8n-mcp "npx -y n8n-mcp" --env "MCP_MODE=stdio" --env "N8N_API_URL=http://localhost:5678" --env "N8N_API_KEY=<YOUR_N8N_KEY>" --trust ``` ## 🧠 How to Use Once installed and reloaded (`/skills reload`), just talk to Gemini: * *"Create a workflow that listens to a Webhook and sends a message to Slack."* * *"Fix the expression error in this node."* * *"Analyze my active workflows and suggest optimizations."* ## 🤝 Contribution Fork this repo, improve the skills, and open a PR! Let's build the best n8n AI tooling together. --- *Adapted for Gemini CLI by matheus-cabelo. Original concept by czlonkowski.*
