​
n8n Server

​
Overview

The n8n server provides comprehensive integration with n8n automation platform, enabling AI assistants to manage workflows, monitor executions, and trigger automations programmatically.

​
Getting Started

1

Connect to n8n

Add the n8n server to your Nexus environment through the server directory.
2

Configure API Access

Provide your n8n instance API URL and API key for authentication.
3

Test Connection

Start with a simple command like list workflows to verify the connection works properly.

​
What You Can Do

Workflow Management

Create, update, activate, and delete n8n workflows programmatically

Execution Monitoring

Track workflow executions, view results, and monitor automation performance

Webhook Triggers

Execute workflows via webhook calls with custom input data and headers

Automation Control

Activate and deactivate workflows to control when automations run

​
Use Cases

  • Dynamic Workflow Creation: Build workflows programmatically based on business requirements
  • Conditional Automation: Activate/deactivate workflows based on schedules or events
  • Bulk Operations: Manage multiple workflows simultaneously across projects
  • Integration Orchestration: Coordinate complex multi-step automations
  • Execution Tracking: Monitor workflow success rates and performance metrics
  • Error Analysis: Identify and analyze failed executions for troubleshooting
  • Performance Optimization: Track execution duration and optimize slow workflows
  • Audit Trail: Maintain logs of workflow changes and execution history
  • Webhook Integration: Trigger workflows from external systems via webhooks
  • Data Processing: Process incoming data through automated workflow pipelines
  • Notification Systems: Set up automated alerts and notification workflows
  • API Orchestration: Chain multiple API calls through workflow automation

​
Available Tools (11)

Complete lifecycle management of n8n workflows from creation to deletion.Core Workflow Operations
Retrieve a list of all workflows with optional filtering by active/inactive status
Retrieve detailed information about a specific workflow by ID
Create new workflows with nodes, connections, and configuration settings
Modify existing workflows including nodes, connections, and metadata
Remove workflows permanently from the n8n instance
Workflow State Management
Enable workflows to run automatically based on their trigger conditions
Disable workflows to prevent automatic execution while preserving configuration
Monitor and manage workflow execution history and results.
Retrieve workflow executions with filtering by workflow, status, and pagination support
Get detailed execution information including node results and error data
Remove specific execution records from the execution history
Use status filters (‘success’, ‘error’, ‘waiting’, ‘canceled’) to find specific execution types quickly.
Execute workflows via HTTP webhooks with custom data and headers.
Trigger workflow execution via webhook with optional input data and custom headers
Pro Tip: Use meaningful workflow names for webhook endpoints and include error handling in your workflows for robust webhook processing.

​
Resources

The n8n server provides direct access to workflow and execution data through resource endpoints.
Access entire data collections for browsing and discovery:

Workflows

n8n://workflows
Access the complete workflow directory

Execution Statistics

n8n://execution-stats
View execution metrics and performance data
Access specific records when you know their ID:

Workflow Details

n8n://workflows/{id}
Get comprehensive workflow information including nodes and connections

Execution Details

n8n://executions/{id}
Get detailed execution results including node outputs and error information
Pro Tip: Use collection endpoints to discover workflows and executions, then switch to individual record endpoints for detailed analysis.

​
Configuration Requirements

​
Authentication Setup

The n8n server requires API key authentication with your n8n instance:
  • API Key: Your n8n instance API key (generated in n8n Settings → API Keys)
  • API URL: Your n8n instance API endpoint (e.g., https://n8n.example.com/api/v1)
  • Webhook Credentials (optional): Username/password for webhook authentication
  • Default API URL: https://n8n.civic.com/api/v1
  • Default Webhook Username: username
  • Default Webhook Password: password
Ensure your n8n instance is accessible from the internet and API access is enabled in your n8n configuration.
The n8n server requires appropriate API permissions in your n8n instance to create, modify, and execute workflows.
