Highlights

  • Automatic snapshots + rollback: before every update, partial edit, or delete, the previous state of the workflow is saved locally. n8n_rollback_workflow restores any version — and can even recreate a deleted workflow. Agents can now edit workflows without fear.
  • Real end-to-end testing: n8n_trigger_webhook calls a Webhook-trigger workflow on your instance and returns the actual HTTP response, closing the build → test → fix loop.
  • Guided MCP prompts: build-workflow and fix-workflow walk any MCP client through the full validated build and repair process.
  • Node catalog x3: from 19 to ~60 curated nodes — more triggers, data utilities, databases (Postgres, MySQL, MongoDB, Redis, Supabase, Airtable, Notion, S3), Google/Microsoft, messaging (Discord, WhatsApp, Twilio, Teams), business apps (GitHub, Jira, HubSpot, Stripe, Shopify), and LangChain AI sub-nodes.
  • Docker support: ship the server as a container with persistent snapshot storage.
  • Automated releases: publishing a GitHub release now publishes to npm with provenance via CI.

55 tools, 2 prompts. See the CHANGELOG for details.
