# Workflow as a Tool

Workflow as a tool means taking an entire multi-step automation - a chain of nodes that hits an API, transforms data, writes to a database - and exposing it to an agent as one callable function. The agent does not know or care how many steps sit behind the call; it sees a name, a description, and a parameter schema. Cole's framing is blunt: "my favorite part is you can literally call any n8n workflow as a tool" [0:05:13]. The payoff is leverage. An automation platform already ships integrations with hundreds of services, so wiring workflows in as tools hands the agent that entire catalog at once: "I use n8n workflows as my agent tools to interact with things like slack and Google drive it is just the perfect combo to build AI agents super quickly" [0:01:39].

The wiring is deliberately identical to any other tool. You attach the workflow to the agent node the same way you attach a hosted API: "we're going to do this through making n8n workflows as tools that we attach to our tools agent here just like we did with the brave search API" [0:15:41]. What makes it work is the two pieces of metadata every tool needs - a schema and a trigger condition: "you just tell the AI agent how to use this workflow like what parameters to give and then also you tell it when to use that workflow just like you would with any tool that you might Define in custom code" [0:05:28]. That last clause is the point. There is no special no-code semantics here; the same [tool design](./tool-design.md) discipline that governs a Python function - unambiguous name, precise description, tight parameter list - governs a workflow.

Architecturally this is the clean seam between the two halves of [agents vs. workflows](./agents-vs-workflows.md). The agent supplies non-deterministic reasoning about *which* capability to invoke; the workflow supplies a [deterministic](./deterministic-workflows.md) execution path once invoked. Failures stay contained inside the workflow rather than inside the model's reasoning, which is why this pattern underpins [hybrid no-code + code architectures](./hybrid-no-code-and-code.md) - a coded agent calling no-code workflows, or the reverse.
