What is an agentic workflow?
An agentic workflow is a process where an AI agent decides which tools to call and in what order to reach a stated goal, instead of following a fixed sequence of steps. You describe the outcome; the agent plans, calls APIs, reads results, and adjusts. Traditional automation runs the same path every time.
Agentic workflow versus fixed automation
A Zapier zap or a cron job runs a predetermined path. Trigger fires, step one, step two, done. That is reliable and easy to reason about, and it breaks the moment the situation differs from the one it was built for.
An agent is given a goal and a set of tools. It works out the path, and it can take a different path next time because the inputs changed. The gain is flexibility. The cost is that the behaviour is no longer fully predictable, which is why the interesting design question is where a person still signs off.
What an agent needs from a tool
- A narrow, nameable job. Tools an agent can use well do one thing with a clear name. Broad tools with many modes produce unreliable selection.
- Structured output. An agent chains steps by reading results. Typed JSON is composable; prose has to be re-parsed by the model at every hop.
- Context it does not have to carry. If brand voice lives on the server, the agent does not spend context on it and cannot get it wrong.
- Honest errors. An agent can recover from a 429 with a reset header. It cannot recover from a 200 containing an apology.
A worked example
A content agent is told to draft this week's posts about a launch. It reads the changelog, calls a content endpoint once per platform, calls it again for a thread, writes the drafts into a review queue, and posts a summary to Slack. Nobody specified that sequence. The agent assembled it from the goal and the tools available.
The human step is unchanged and deliberate: the drafts wait for approval. Automating production while keeping judgment is the whole point of the arrangement.
Agentic workflow questions
What is the difference between an agentic workflow and automation?
Automation executes a fixed sequence defined in advance. An agentic workflow gives a model a goal and a set of tools and lets it decide the sequence, which means it can handle situations the author did not anticipate, at the cost of running a different path each time.
Which tools run agentic workflows?
Claude Code runs them from a terminal against your files and any HTTP API. n8n and Make support agent nodes inside otherwise conventional workflows. Custom agents built on a model API work the same way, calling tools until the goal is met.
Do agents need an MCP server to call an API?
No. An agent can call any REST endpoint directly with curl or fetch. An MCP server is the cleaner option for a workflow you run repeatedly, because it exposes the operation as a named tool with typed inputs instead of a shell command.
