+# Docker MCP Gateway on LXC 303
+
+## Infrastructure
+
+- **VMID:** 303
+- **Hostname:** mcp-gateway
+- **IP:** 10.10.0.231
+- **OS:** Ubuntu 24.04
+- **Resources:** 2 cores, 4GB RAM, 16GB disk
+- **Type:** Privileged LXC on Proxmox
+- **SSH alias:** `mcp-gateway`
+
+## Purpose
+
+Centralized Docker MCP Gateway service hosting 220+ catalog MCP servers. AI clients (e.g. Claude Code) connect to a single HTTP endpoint and can discover/enable tools on the fly via dynamic tools: `mcp-find`, `mcp-add`, `mcp-remove`.
+
+## Deployment
+
+- Docker CE installed on LXC
+- Container: `docker/mcp-gateway`
+- Compose file: `/opt/mcp-gateway/docker-compose.yml`
+- Flags: `--transport=streaming --port=8811`
+- Endpoint: `http://10.10.0.231:8811/mcp`
+
+## AppArmor Fix for Docker-in-LXC
+
+Required these lines in `/etc/pve/lxc/303.conf`:
+
+```
+lxc.apparmor.profile: unconfined
+lxc.cap.drop:
+lxc.mount.auto: proc:rw sys:rw
+```
+
+Without these, Docker cannot start inside a privileged LXC due to AppArmor restrictions.
+
+## Claude Code Integration
+
+Registered as user-scope MCP server:
+
+```bash
+claude mcp add --transport http --scope user docker-mcp-gateway http://10.10.0.231:8811/mcp
+```
+
+Adds the following to `~/.claude.json` mcpServers:
+
+```json
+{
+  "docker-mcp-gateway": {
+    "type": "http",
+    "url": "http://10.10.0.231:8811/mcp"
+  }
+}
+```
