How I Built an AI Agent That Actually Works: n8n + Needle MCP

TL;DR: Plug the Needle Remote MCP endpoint into n8n's AI Agent node and let GPT-4o (or Turbo) search, summarize, and update every PDF, slide deck, Jira ticket, or email in seconds—no servers, no vector-DB babysitting, just an HTTPS URL and a Bearer token.

Why this matters

• LLMs without context are parrots—Needle pipes your content through RAG
• n8n already runs your automations—add a chat front-end
• Remote MCP = zero infra—Needle runs the server for you

Setup steps

1. Add Needle credential in n8n (Header Auth)
2. Wire up the AI Agent graph
3. Smoke-test: "List my Needle collections"
4. Build real-world recipes (Zendesk replies, sales one-pagers, research digests)
