What this workflow does
This AI workflow has 25 nodes and runs when a chat message arrives. Along the way it connects OpenAI Chat Model and SerpApi (Google Search).
How it runs
Trigger: When a chat message arrives.
- Tool Finder (AI Agent): runs an AI agent, with model: OpenAI Chat Model; 1 tool (SerpAPI); memory: Window Buffer Memory; output parser: Structured Output Parser
- Reviewer (AI Agent): runs an AI agent, with model: OpenAI Chat Model; 1 tool (SerpAPI)
- Reviewer (AI Agent): runs an AI agent, with model: OpenAI Chat Model; 1 tool (SerpAPI)
- Reviewer (AI Agent): runs an AI agent, with model: OpenAI Chat Model; 1 tool (SerpAPI)
- Reviewer (AI Agent): runs an AI agent, with model: OpenAI Chat Model; 1 tool (SerpAPI)
- Reviewer (AI Agent): runs an AI agent, with model: OpenAI Chat Model; 1 tool (SerpAPI)
- Merge: merges the data from its input branches
- Aggregate: combines items into one
- Compiler (AI Agent): runs an AI agent, with model: OpenAI Chat Model

Before you upgrade to n8n 3.0
2 things in this workflow are removed in n8n 3.0. Fix them before you upgrade:
- SerpApi (Google Search) in SerpAPI1, SerpAPI, SerpAPI3…: no direct replacement: call the SerpApi REST API with an HTTP Request tool, or use a verified community node.
- AI Agent v1 (old agent modes) in Reviewer 1 (v1.7), Reviewer 2 (v1.7), Reviewer 3 (v1.7)…: replace with Latest AI Agent node (Tools Agent). For SQL Agent, use a Postgres or MySQL tool with a recent AI Agent.
Rather not rewrite it? Many of these flows can be rebuilt in Make (free plan).
| Removed in 3.0 | Replace with |
|---|---|
| SerpApi (Google Search) SerpAPI1, SerpAPI, SerpAPI3, SerpAPI4, SerpAPI5, SerpAPI2 | No direct replacement: call the SerpApi REST API with an HTTP Request tool, or use a verified community node |
| AI Agent v1 (old agent modes) Reviewer 1 (v1.7), Reviewer 2 (v1.7), Reviewer 3 (v1.7), Reviewer 4 (v1.7), Reviewer 5 (v1.7), Compiler (v1.7), Tool Finder (v1.7) | Latest AI Agent node (Tools Agent). For SQL Agent, use a Postgres or MySQL tool with a recent AI Agent. |
