# NEW Simplified Langflow Configuration
## What Changed
The server now **automatically finds SWI-Prolog** without needing PATH configuration or wrapper scripts!
## New Configuration (Much Simpler!)
### In Langflow UI:
**Name:** `swipl-prolog`
**Command:** `node`
**Arguments:** `/Users/keeper/Developer/MacOs/model-context-lab/products/swipl-mcp-server/dist/index.js`
**Environment Variables:** (optional)
- `SWI_MCP_READY_TIMEOUT_MS` = `30000`
That's it! No PATH configuration needed.
---
## Or Using Full Node Path (if node not in PATH):
**Command:** `/Users/keeper/.nvm/versions/node/v22.18.0/bin/node`
**Arguments:** `/Users/keeper/Developer/MacOs/model-context-lab/products/swipl-mcp-server/dist/index.js`
---
## How It Works
The server searches for SWI-Prolog in these locations automatically:
- `/opt/homebrew/bin/swipl` ✅ (Your installation)
- `/usr/local/bin/swipl`
- `/usr/bin/swipl`
- `/opt/local/bin/swipl`
- System PATH
**No manual configuration needed!**
## Expected Result
After saving the configuration:
- Wait 5-10 seconds
- Langflow should show "Connected"
- 17 tools should appear in the dropdown
- Tools include: help, capabilities, query_start, knowledge_base_load, etc.
## Test It
Remove the old wrapper script configuration and use the simple one above. It should just work!
