{
  "mcpServers": {
    "n8n": {
      "command": "npx",
      "args": ["n8n-mcp"]
    }
  }
}

2. Hermes Agent (config.yaml)

Business Operator Use Cases

  1. Workflow Discovery — "What nodes can I use to connect my PostgreSQL database to Slack?" — agent finds the right nodes and shows wiring
  2. Automation Scaffolding — "Build me a workflow that monitors Stripe for failed payments and posts to a Slack channel" — agent generates the workflow JSON
  3. Template Matching — "I need to sync HubSpot deals to Google Sheets" — agent finds the closest template from 2,352 options
  4. Node Documentation Lookup — "What parameters does the HTTP Request node accept for OAuth2?" — agent retrieves the complete schema
  5. AI Pipeline Design — Agent recommends the 265 AI-capable nodes for building LLM-powered automation pipelines
