+#### MCP Gateway — CT 303 (10.10.0.231)
+**Purpose**: Docker MCP Gateway — centralized MCP server proxy for Claude Code
+**SSH alias**: `mcp-gateway`
+**Service**: `docker/mcp-gateway` v2.0.1 on port 8811 (`http://10.10.0.231:8811/mcp`)
+**MCP servers**: n8n (23 tools, connects to LXC 210), Gitea (109 tools, connects to git.manticorum.com)
+**Config**: `/home/cal/mcp-gateway/` — `secrets.env`, `config/config.yaml`, `config/registry.yaml`, `gitea-catalog.yaml`
+**Note**: Uses `--servers` flag for static server activation (Docker Desktop secret store unavailable on headless Engine). Custom catalog adds Gitea MCP via `docker.gitea.com/gitea-mcp-server` image.

 **Two-tier system:**
 - **Tier 1** (`health_check.py`): Pure Python, runs every 5 min via n8n. Checks containers, systemd services, disk/memory/load. Auto-restarts containers when allowed. Exit 0=healthy, 1=auto-fixed, 2=needs Claude.
 - **Tier 2** (`client.py`): Full diagnostic toolkit used by Claude during escalation sessions.
