dsh-mcp-tunnel: Spinning Up an Outbound Tunnel for a Local MCP Server

`dsh-mcp-tunnel` is a networking tool plugin for DeepSeek Harness (DSH) designed to address the issue of local MCP Servers being inaccessible to remote Agents. It creates secure tunnels via a Docker Compose stack, using `mcp-proxy` and `cloudflared` to map local services to HTTPS URLs without exposing local ports. The plugin supports automatic configuration generation, certificate management, and CLI commands, but does not automatically modify host configurations; users must manually add the generated configuration snippets. Before use, a Docker environment is required, and production deployments must include their own authentication layer.
