About n8n (AI Workflow Automation) MCP Server
Connect your n8n instance to any AI agent and take full control of your node-based workflow automation, execution diagnostics, and project orchestration through natural conversation.
LlamaIndex agents combine n8n (AI Workflow Automation) tool responses with indexed documents for comprehensive, grounded answers. Connect 7 tools through the Vinkius and query live data alongside vector stores and SQL databases in a single turn — ideal for hybrid search, data enrichment, and analytical workflows.
What you can do
- Workflow Orchestration — List all managed automation workflows and retrieve detailed JSON logic nodes, including link mappings and trigger configurations directly from your agent
- Execution Diagnostics — Extract historical execution logs to track success/failure boundaries and retrieve absolute trace logs for rapid debugging of automation failures
- Node-Level Inspection — Deep-dive into specific execution IDs to extract bounded node-level output blocks and identify exact processing errors natively
- Credential Audit — List metadata mapping saved automation credentials to verify system types and IDs without exposing literal secure tokens
- Collaborative Visibility — Enumerate provisioned team users and assigned roles to verify access targets across your n8n infrastructure securely
- Organizational Tags — List arbitrary category tags used to group and sort complex workflow logic dimensions across your automation workspace
- Metadata Inspection — Retrieve precise graph representations for specific workflows to understand the underlying logic and data transformation flows instantly
The n8n (AI Workflow Automation) MCP Server exposes 7 tools through the Vinkius. Connect it to LlamaIndex in under two minutes — no API keys to rotate, no infrastructure to provision, no vendor lock-in. Your configuration, your data, your control.
