# Custom Tools

> Build your own multi-step workflow automations.

## Creating a custom tool

<Steps>
  <Step title="Navigate to Tools">
    Go to **Tools** in the sidebar and click **Create Tool**.
  </Step>

  <Step title="Basic information">
    Set a name, description, and icon for your tool.
  </Step>

  <Step title="Define parameters">
    Specify the input parameters your tool accepts as a JSON schema. These values can be provided when the tool is run.
  </Step>

  <Step title="Add steps">
    Build your workflow by adding steps in sequence. Each step calls a function with specific inputs.
  </Step>

  <Step title="Configure output">
    Optionally define an output schema to structure the tool's final result.
  </Step>
</Steps>

## Step configuration

Each step in your tool maps to a function call:

| Field             | Description                                                     |
| ----------------- | --------------------------------------------------------------- |
| **Function**      | Which built-in or integration function to execute               |
| **Input mapping** | Map tool parameters or previous step outputs to function inputs |
| **Step order**    | Position in the execution sequence                              |

## Data flow between steps

Steps can reference outputs from previous steps. Use the step output reference syntax to pass data forward through your workflow.

## Marketplace templates

You can clone tools from the **Marketplace** to get started quickly:

* Browse available templates by category
* Clone a template to your organization
* Customize the steps and parameters for your use case

## Running custom tools

Custom tools support all execution methods:

* **Manual** — run from the dashboard with custom input
* **API** — `POST /v1/tools/run/{toolId}` with JSON body
* **Webhook** — configure a webhook trigger for external systems
* **Agent** — attach the tool to an agent for dynamic invocation
