n8n

n8n is a visual, node-based workflow automation platform that anchors this cluster. It competes with Zapier and Make.com but differentiates on self-hosting, native code nodes, AI-first features (agents, guardrails, AI builder, Chat Hub), and a deep integration ecosystem (1100+ nodes, 2700+ templates). Throughout the cluster, n8n evolves from a primary build surface to a backend layer that Claude Code can discover, execute, and fix via its instance-level MCP server. n8n 2.0 (December 2025) focused on back-end scalability and introduced subworkflow wait-and-return behaviour.

Key facts

• Offers both n8n Cloud (managed, includes AI workflow builder) and self-hosted (community edition, no AI builder but unlimited executions)
• Core nodes include schedule trigger, event triggers, subworkflows, split-out, aggregate, set, if, switch, code, HTTP request, loop, webhook, AI agent, tools, Google Sheets
• Version 1.119 introduced native guardrail nodes (keywords, jailbreak, NSFW, PII, secret keys, topical alignment, URLs, custom)
• Version 1.118 enabled OpenAI responses API in the chat model node (web search, file search, code interpreter, MCP built-in tools)
• Version 1.21.2 introduced instance-level MCP with OAuth and access token authentication
• A newer official MCP beta discussed in ^[src-086] extends the pattern from search/get/execute toward agent-assisted workflow creation and editing with reference documents.
• Version 2.0 (beta Dec 8 2025, stable Dec 15) focused on security, reliability, and scalability; subworkflows must now be published before being callable
• Exposes a REST API at /api/v1 for programmatic workflow creation, retrieval, and management
• Has a 39-page community-distributed essential-nodes reference used as a learning scaffold
• n8n Desk uses n8n as the execution layer behind a desktop agent interface, with chat, co-work, workflow-building, encrypted credentials, and visible execution history ^[src-086].
