Ready for 3.0Ready for 3.0. This template uses no nodes that n8n 3.0 removes. No removed nodes, versions or helpers found. Static check, last run 2026-10-19.
What this workflow does
This AI workflow has 11 nodes and runs when an MCP client calls one of its tools (plus 1 other trigger). Along the way it connects Embeddings OpenAI, Reranker Cohere, Google Sheets and Perplexity and 4 more.
How it runs
Trigger: When an MCP client calls one of its tools (plus 1 other trigger).
- AI Agent: runs an AI agent, with model: OpenAI Chat Model; 1 tool (MCP Client knowledge); memory: Postgres Chat Memory
Services it uses
Before you upgrade to n8n 3.0
Nothing in this workflow is removed in n8n 3.0, so it should import and run after the upgrade.
