# Workflow Tools

This page documents the tools available for managing n8n workflows.

## Overview

Workflow tools allow AI assistants to manage n8n workflows, including creating, retrieving, updating, deleting, activating, and deactivating workflows. These tools provide a natural language interface to n8n's workflow management capabilities.

## Available Tools

### workflow_list

Lists all workflows with optional filtering.

```

**Example Usage:**

```javascript
// List all workflows
const result = await useWorkflowList({});

## Error Handling

All workflow tools can return the following errors:

| Error | Description |
|-------|-------------|
| Authentication Error | The provided API key is invalid or missing |
| Not Found Error | The requested workflow does not exist |
| Validation Error | The input parameters are invalid or incomplete |
| Permission Error | The API key does not have permission to perform the operation |
| Server Error | An unexpected error occurred on the n8n server |

## Best Practices

- Use `workflow_list` to discover available workflows before performing operations
- Validate workflow IDs before attempting to update or delete workflows
- Check workflow status (active/inactive) before attempting activation/deactivation
- Include only the necessary fields when updating workflows to avoid unintended changes
