Comprehensive guide for building n8n workflows using MCP tools with node discovery, validation, and workflow management.

• Provides four tool categories: node discovery (search, get details), configuration validation with multiple profiles, workflow management (create, update, deploy), and access to 2,700+ templates
• Critical distinction between nodeType formats: nodes-base.* for search/validate tools versus n8n-nodes-base.* for workflow creation and updates
• Validation profiles (minimal, runtime, ai-friendly, strict) and detail levels (standard recommended, full for debugging) prevent common configuration errors and token waste
• Iterative workflow building pattern with 56-second average between edits, auto-sanitization on all nodes, and smart parameters (branch, case) for multi-output node connections
• Includes performance benchmarks, common mistakes, and unified tool reference covering get_node modes, validate_node profiles, and template deployment
