N8n Fabric

Workflow Automation Fabric Layer

n8n-fabric wraps n8n with an MCP server, Qdrant vector storage, and Redis caching—making workflows searchable, memorable, and orchestratable alongside git-steer and aiana.

Features

MCP Server

• Full n8n API access - Workflows, executions, credentials, nodes
• Semantic search - Find workflows by meaning, not just name
• Cross-fabric coordination - Works with git-steer and aiana

Workflow Intelligence

• Vector embeddings - Workflows stored in Qdrant for similarity search
• Pattern recognition - "How did I handle webhook → transform → API?"
• Playbook recall - Find and reuse proven workflow patterns

Infrastructure

• Docker Compose - One command to run full stack
• Redis caching - Fast workflow metadata and execution state
• PostgreSQL - n8n's persistent storage

---

Quick Start

Docker Compose (Recommended)

# Clone repository
git clone https://github.com/ry-ops/n8n-fabric
cd n8n-fabric

# Start full stack (n8n + Qdrant + Redis + PostgreSQL)
docker compose up -d

# Check status
docker compose ps

# View n8n UI
open http://localhost:5678

Local Development

# Install dependencies
uv sync

# Set environment variables
export N8N_URL=http://localhost:5678
export N8N_API_KEY=your-api-key

# Run MCP server
uv run n8n-fabric-mcp

Configuration

Environment Variables

Variable	Description	Default
N8N_URL	n8n API URL	http://localhost:5678
N8N_API_KEY	n8n API key	(required)
QDRANT_URL	Qdrant URL	http://localhost:6343

Fabric Ecosystem

n8n-fabric is part of the ry-ops fabric ecosystem:

Fabric	Role	MCP Tools
n8n-fabric	Workflow execution, playbooks	Workflows, executions, credentials
git-steer	Repo lifecycle, version control	Repos, branches, security, PRs
aiana	Semantic memory, pattern recall	Memory search, context injection

Cross-Fabric Examples

"Remember how I built the Slack notification workflow"
  → aiana searches memory
  → n8n-fabric retrieves workflow
  → Returns full workflow JSON

"Create a new webhook-to-Slack workflow and commit it"
  → n8n-fabric creates workflow
  → git-steer commits workflow JSON to repo
  → aiana indexes for future recall

"Run my deployment notification playbook"
  → aiana recalls playbook pattern
  → n8n-fabric executes workflow
  → git-steer logs deployment
