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 16 nodes and runs when another workflow calls it. Along the way it connects OpenRouter Chat Model, MCP Client, Qdrant Vector Store and Embeddings Google Gemini and 1 more.
How it runs
Trigger: When another workflow calls it.
- ReadIncidentContext (Code): runs custom JavaScript code
- Call 'attachmentsAnalyzer' (Execute Sub-workflow): calls another n8n workflow
- Merge: merges the data from its input branches
- Set: empty attachments (Edit Fields (Set)): sets 2 fields: attachments_context, attachments_count
- SetVars (Edit Fields (Set)): sets 12 fields: GITHUB_ORG, K8S_NAMESPACE, K8S_CLUSTERS…
- AI Agent: runs an AI agent, with model: OpenRouter Chat Model; 6 tools (K8S, Github, Grafana, Mattermost…)
- Post a message (Mattermost): uses Mattermost
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.
