|
**Repository**: https://github.com/czlonkowski/n8n-skills
|
|
|
|
**Purpose**: 7 complementary skills that provide expert guidance on using n8n-mcp MCP tools effectively for building n8n workflows.
|
|
|
|
**Architecture**:
|
|
- **n8n-mcp MCP Server**: Provides data access (800+ nodes, validation, templates, workflow management)
|
|
- **Claude Skills**: Provides expert guidance on HOW to use MCP tools
|
|
- **Together**: Expert workflow builder with progressive disclosure

|
## Key MCP Tools
|
|
|
|
The n8n-mcp server provides these unified tools:
|
|
|
|
### Node Discovery
|
|
- `search_nodes` - Find nodes by keyword
|
|
- `get_node` - Unified node info with detail levels (minimal, standard, full) and modes (info, docs, search_properties, versions)
|
|
|
|
### Validation
|
|
- `validate_node` - Unified validation with modes (minimal, full) and profiles (runtime, ai-friendly, strict)
|
|
- `validate_workflow` - Complete workflow validation
|
|
|
|
### Workflow Management
|
|
- `n8n_create_workflow` - Create new workflows
|
|
- `n8n_update_partial_workflow` - Incremental updates (17 operation types including `activateWorkflow`)
|
|
- `n8n_validate_workflow` - Validate by ID
|
|
- `n8n_autofix_workflow` - Auto-fix common issues
|
|

## Working with This Repository
|
|
|
|
### When Adding New Skills
|
|
1. Create skill directory under `skills/`
|
|
2. Write SKILL.md with frontmatter
|
|
3. Add reference files as needed
|
|
4. Create 3+ evaluations in `evaluations/`
|
|
5. Test thoroughly before committing
|
|
|
|
### Skill Activation
|
|
Skills activate automatically when queries match their description triggers:
|
|
- "How do I write n8n expressions?" → n8n Expression Syntax
|
|
- "Find me a Slack node" → n8n MCP Tools Expert
|
|
- "Build a webhook workflow" → n8n Workflow Patterns
|
|
|
|
### Cross-Skill Integration
|
|
Skills are designed to work together:
|
|
- Use n8n Workflow Patterns to identify structure
|
|
- Use n8n MCP Tools Expert to find nodes
|
|
- Use n8n Node Configuration for setup
|
|
- Use n8n Expression Syntax for data mapping
|
|
- Use n8n Code JavaScript/Python for custom logic
|
|
- Use n8n Validation Expert to validate
|
|
|
|
