🎯 Available Nodes

📄 MediaWiki Page

Complete page management with support for:

• Get: Retrieve the content of any page
• Edit: Create new pages or update existing pages with content (automatically detects if page exists)
• Delete: Remove pages with optional deletion reason

🔍 MediaWiki Search

• Search: Find pages matching your search query with configurable result limits

🤖 AI Integration

Both nodes work seamlessly with n8n's AI Agent nodes:

1. Add nodes to your workflow - Use MediaWiki Page and MediaWiki Search as regular nodes
2. Connect to AI Agents - These nodes automatically become available as AI tools when connected to AI Agent nodes
3. "Let AI fill this in" buttons - Parameters show toggle buttons allowing AI to automatically fill values based on context
4. Intelligent automation - AI agents can read, edit, delete, and search MediaWiki content autonomously

Example AI Usage:

• AI Research Assistant: "Find information about quantum computing on Wikipedia and create a summary page"
• Content Management: "Update the company wiki page with the latest product information"
• Knowledge Discovery: "Search for pages related to machine learning and extract key concepts"

💡 Parameter Configuration

MediaWiki Page Node

• Operation: Select get, edit, or delete
• Page Title: The title of the page to operate on (AI can fill automatically)
• Page Content: Content for edit operations (AI can generate) - creates page if it doesn't exist, updates if it does
• Delete Reason: Optional reason for deletion (AI can suggest)

MediaWiki Search Node

• Search Term: Query to find matching pages (AI can formulate)
• Limit: Maximum number of results (1-500, defaults to 10)

🛠️ Development

🚀 Setup

1. Clone: git clone https://github.com/matheusfillipe/n8n-mediawiki
2. Install: npm install
