How to Use the n8n (AI Workflow Automation) MCP in Windsurf

Q: How do I connect n8n (AI Workflow Automation) to Windsurf?

Edit /.codeium/windsurf/mcpconfig.json and add the server details under the mcpServers key. Cascade auto-discovers the tools the second you hit refresh in the MCP panel.

Q: Can Cascade debug failed n8n (AI Workflow Automation) runs in Windsurf?

Yes. The agent calls listworkflowexecutions to find errors, then uses getexecutiondetails to pull the exact trace logs. You get the failure context right in your IDE.

Q: What is the best way to find a specific n8n (AI Workflow Automation) process using Windsurf?

Ask Cascade to search by tag. It runs listworkflowtags to find the right category, then filters the active processes to locate your target.

Q: How does this MCP handle my saved API keys?

The liststoredcredentials tool only returns metadata about your saved authentication blocks. Your actual secret tokens never leave the n8n database. Windsurf just sees the names and types of connections you have configured.

Give Cascade direct access to your n8n (AI Workflow Automation) instance. Windsurf can audit workflows and pull execution traces instantly.

Audit n8n workflows directly inside Windsurf

Cascade uses `list_workflows` to map out your entire automation setup the second you ask for it. You don't need to open a browser tab to figure out what is running. It pulls the active definitions and drops them into your editor context. If a specific process looks suspicious, the agent chains `get_workflow_details` to inspect the node configurations. It reads the raw JSON structure of your automations. You just tell Windsurf to find the broken webhook, and Cascade does the digging.

Track process failures via MCP Server

This MCP Server exposes `list_workflow_executions` so your agent can monitor recent runs. When an API call fails in production, Cascade grabs the error logs automatically. It filters the history to find the exact moment the process died. For deep debugging, it runs `get_execution_details` on the specific failed ID. Windsurf reads the trace logs node by node. You see exactly which HTTP request timed out before writing a single line of fix code.

Map tags and user access

Managing a messy instance gets easier when your client can run `list_workflow_tags`. Cascade groups your automations by project or department instantly. It builds a map of how your background jobs are organized. It also checks who has access using `list_instance_users` and `list_stored_credentials`. You can ask Windsurf to verify if a former contractor still has active API keys saved in the system. The agent lists the metadata without exposing the actual secrets.
