Docker MCP Gateway LXC 303 Setup

Infrastructure

  • LXC: 303, IP: 10.10.0.231, SSH alias: mcp-gateway
  • Container: docker/mcp-gateway v2.0.1 on port 8811
  • Claude Code connection: http://10.10.0.231:8811/mcp in ~/.claude.json under mcpServers.docker-mcp-gateway (type: http)

Docker Run Command

docker run -d --name mcp-gateway --restart unless-stopped -p 8811:8811 \
  -v /var/run/docker.sock:/var/run/docker.sock \
  -v /home/cal/mcp-gateway/secrets.env:/secrets/secrets.env:ro \
  -v /home/cal/mcp-gateway/config/config.yaml:/root/.docker/mcp/config.yaml \
  -v /home/cal/mcp-gateway/config/registry.yaml:/root/.docker/mcp/registry.yaml \
  -v /home/cal/mcp-gateway/gitea-catalog.yaml:/catalogs/gitea-catalog.yaml:ro \
  docker/mcp-gateway \
  --transport=streaming --port=8811 \
  --secrets=/secrets/secrets.env \
  --additional-catalog=/catalogs/gitea-catalog.yaml \
  --servers=n8n --servers=gitea

Files on LXC at /home/cal/mcp-gateway/

  • secrets.env — contains n8n.api_key=<JWT> and gitea.token=<token>
  • config/config.yaml — server configs (n8n api_url, gitea host)
  • config/registry.yaml — enabled servers registry
  • gitea-catalog.yaml — custom catalog entry for Gitea MCP server

Notes

  • Servers n8n and gitea are pre-started via --servers flag to bypass secrets validation issues on headless Docker Engine (no Docker Desktop)
