A chatbot answers questions; an agent gets work done. It plans, searches, calls tools and reports the result.
Agents alongside workflows
In practice agents sit alongside workflows such as n8n: the workflow detects an event and the agent decides what to do — for example read an invoice, record it and alert on a mismatch.
Several agents, several roles
For complex work, several agents with separate roles coordinate. Protocols such as MCP standardise safe agent access to tools and data.
Start small
The key is to start small: one repetitive process, one metric, and a human review path for sensitive decisions.
