+## Ouranos Deployment
+
+The FreeCAD Robust MCP Server runs on `caliban.incus` and is exposed via Titania's HAProxy with TLS termination.
+
+### Architecture
+
+```
+External Agent (e.g., Claude Desktop / MCP Switchboard)
+        │  MCP Protocol (Streamable HTTP, TLS)
+        │  https://freecad-mcp.ouranos.helu.ca/mcp
+        ▼
+  Titania HAProxy (TLS termination, wildcard cert)
+        │  http://caliban.incus:22032/mcp
+        ▼
+  FreeCAD Robust MCP Server (HTTP transport mode)
+        │  XML-RPC (localhost:9875)
+        ▼
+  FreeCAD (GUI or headless)
+```
+
+### Integration
+
+The MCP URL is registered in `group_vars/all/vars.yml`:
+
+```yaml
+freecad_mcp_url: https://freecad-mcp.ouranos.helu.ca/mcp
+```
+
+The route is served via Titania's HAProxy using the existing `*.ouranos.helu.ca` Let's Encrypt wildcard certificate.
+
+**To deploy:** `ansible-playbook ansible/haproxy/configure.yml`

+## Port Numbering
+
+Well-known ports running as a service may be used: Postgresql 5432, Prometheus Metrics 9100.
+
+However inside a docker project, the number plan needs to be followed to avoid port conflicts and confusion:
+XXXYZ
+XXX Project Number or 220 for external project 
+Y Service: 0 reserved, 1-4 flexible, 5 database, 6 MCP, 7 API, 8 Web App, 9 Prometheus metrics
+Z Instance: The running instance of this app on the same host, starting at 1.  May also be used to handle exceptions.
+
+255 Incus port forwarding: Ports in ths range are forwarded from the Incus host to Incus containers (defined in Terraform)
+
+514ZZ is the syslog port.  Docker containers send their syslog to an Alloy syslog collector port.  ZZ is the application instance, they just need to be different on the same host and increment from 01.
