N8n Mcp Tools Expert

This is for anyone working with n8n workflows through the MCP protocol rather than the UI. It knows the difference between the two nodeType formats that'll trip you up (nodes-base.slack for validation, n8n-nodes-base.slack for workflow operations), pushes you toward detail="standard" instead of wasting tokens on detail="full", and maps out the discover-validate-update cycle that actually works. The smart parameters for IF/Switch branches are clever. Real time savers are the validation profiles and knowing that every workflow update auto-sanitizes all your nodes. Written by someone who's clearly debugged "node not found" errors enough times to document the patterns that matter.

n8n MCP Tools Expert

Master guide for using n8n-mcp MCP server tools to build workflows.

Detailed Guide

Read the detailed guide before executing this skill. It retains the complete procedure and reference material. Treat its safety, prerequisites, and validation requirements as mandatory. For focused work, load the relevant sections; for end-to-end work, read the guide completely.

When to Use

You are using the n8n-mcp toolset to discover nodes, validate configs, or manage workflows.
The task involves choosing the right MCP tool or understanding its expected parameters and usage pattern.
You need guidance on workflow creation or editing through n8n MCP rather than through the n8n UI alone.

Tool Usage Patterns

Pattern 1: Node Discovery (Most Common)

Illustrative workflow; no timing or success benchmark established.

// Step 1: Search (fast!)
const results = await search_nodes({
  query: "slack",
  mode: "OR",  // Default: any word matches
  limit: 20
});
// → Returns: nodes-base.slack, nodes-base.slackTrigger
