Key Takeaway
n8n Agents lets you attach workflows you have already built as tools, keeping set procedures in workflows. The feature announced on September 25 is still a preview, so start with small internal tasks.
Which procedures should you attach as tools?
Procedures with clear inputs and results fit, such as looking up an account, adding a note to a set field, or sending a notification to the person in charge. The narrower the job each tool does, the less room the agent has to call more actions than it needs. Check input validation and failure handling on the workflow side that you attach as a tool.
In which direction do agents and workflows connect?
| Direction | Setup |
|---|---|
| Agent calls a procedure | Connect an existing workflow as a tool |
| Procedure calls an agent | Use the Message an Agent node |
| Sensitive external actions | Check the tool approval setting |
Credentials are connected separately for each tool, and the permission to edit or publish an agent follows n8n roles. Just because the connection works does not mean you need to put a shared admin account into every tool.
What should you test before production?
In a test channel, send both a normal request and one with missing inputs. Also check whether notes or notifications run twice, and whether the task stops when you reject an approval. You need to be able to read the tool inputs, outputs, and error records left in the session to find the cause of a failure.
Can you use it in your own installation?
The official announcement distinguishes availability conditions for Cloud, Community Self-hosted, and Enterprise. Publish only after checking the setup documentation and execution quota that match your installation.
