+# 🧠 AI Research Engine
+
+**Self-hosted agentic AI search infrastructure** — your private research cloud.
+
+AI agents connect via MCP to discover, crawl, index, and synthesize knowledge from the web — all running on your own Proxmox hardware.

+
+## MCP Tools (10)
+
+| Tool | Description |
+|------|-------------|
+| `search_web(query)` | Full-text search across indexed documents |
+| `semantic_search(query)` | Vector search by meaning (Qdrant) |
+| `crawl_url(url)` | Crawl a URL into the index |

+
+## Quick Start
+
+```bash
+# Check status
+curl http://10.30.20.249:8000/api/status
+
+# Search
+curl "http://10.30.20.249:8000/api/search?q=knowledge+graphs"
+
+# Crawl a URL
+curl "http://10.30.20.249:8000/api/crawl?url=https://example.com&depth=1"
+
+# Deep research
+curl "http://10.30.20.249:8000/api/research?topic=LED+grow+lights"
+
+# Generate report
+curl "http://10.30.20.249:8000/api/report?topic=AI+agents"
+```
+
+## Deployment
+
+On CT 145 (10.30.20.249):
+
+```bash
+# Services
