Documentation Lookup AI Agent with Context7 & Gemini

This n8n workflow creates a sophisticated AI agent specialized in documentation lookup, leveraging Context7 for context-aware queries and Google Gemini as the reasoning engine. It uses the Multi-Agent Collaboration Protocol (MCP) to expose the agent via a secure SSE endpoint, allowing external clients like Python scripts, VS Code extensions, or other AI systems to send natural language queries (e.g., 'How do I use Flexbox in Tailwind CSS?') without handling complex orchestration.

The main workflow starts with a Context7 MCP Server Trigger node, which sets up a long, random-path endpoint for 'security by obscurity'. It connects to a Tool Workflow node named 'call_context7_ai_agent', presenting a single tool interface to clients. This tool invokes a sub-workflow containing the core logic: a Context7 Workflow Start node receives the query, followed by a Context7 AI Agent node powered by Gemini.

Benefits include offloading agentic reasoning to n8n, simplifying client-side integration, and enabling scalable documentation queries. Use cases span developer tools, IDE plugins, customer support bots, and internal knowledge bases, saving hours on custom agent builds. Compatible only with self-hosted n8n using community nodes.
