Needs changesNeeds changes. This template uses 2 thing(s) that n8n 3.0 removes: HTTP Request Tool (legacy), AI Agent v1 (old agent modes). 2 breaking item(s) found. Static check, last run 2026-10-19.
What this workflow does
This AI workflow has 7 nodes and runs on Slack events. Along the way it connects HTTP Request, Anthropic Chat Model and Slack. It also calls api.tavily.com over HTTP.
How it runs
Trigger: On Slack events.
- Architect Agent (AI Agent): runs an AI agent, with model: Anthropic Chat Model; 1 tool (Tavily)
- Response (Edit Fields (Set)): sets 1 field: response
- Try Again (Edit Fields (Set)): sets 1 field: response
- Send a message (Slack): uses Slack
Services it uses
HTTP calls to: api.tavily.com
Before you upgrade to n8n 3.0
2 things in this workflow are removed in n8n 3.0. Fix them before you upgrade:
- HTTP Request Tool (legacy) in Tavily: replace with HTTP Request node connected to the AI Agent's Tool input.
- AI Agent v1 (old agent modes) in Architect Agent (v1.7): replace with Latest AI Agent node (Tools Agent). For SQL Agent, use a Postgres or MySQL tool with a recent AI Agent.
- Also check Slack Trigger requires a signing secret on the Slack API credential.
Rather not rewrite it? Many of these flows can be rebuilt in Make (free plan).
| Removed in 3.0 | Replace with |
|---|---|
| HTTP Request Tool (legacy) Tavily | HTTP Request node connected to the AI Agent's Tool input |
| AI Agent v1 (old agent modes) Architect Agent (v1.7) | Latest AI Agent node (Tools Agent). For SQL Agent, use a Postgres or MySQL tool with a recent AI Agent. |
