multi_agent (Multi-Agent Database System) is an n8n automation template that implements a multi-agent system for querying a database via a webhook trigger and OpenAI. Reach for it when you want users or teammates to ask questions about your Postgres data in plain language without writing SQL, when you need an AI-agent pipeline where multiple agents coordinate database lookups, or when you're building a natural-language interface on top of a relational database. Trigger: webhook. Integrations: Postgres Tool, OpenAI. The workflow receives an incoming webhook request, routes it through OpenAI-powered agents that interpret the query, and fetches results from PostgreSQL. Stack: n8n, PostgreSQL, OpenAI API. Deploy by importing the JSON template into your n8n instance — requires a configured Postgres connection and an OpenAI API key. The direction is inbound query handling and data retrieval, not report generation or data export. Works well for teams already running n8n with a Postgres backend; not suitable if your database is not PostgreSQL or n8n is unavailable in your stack.
