NAT traversal has become an increasingly more significant issue in the current real-world network environment. To address this issue, MCP uses one-way communication. One-way communication has the MCP agent initiating the connection to, and polling of commands from, the server. Each request is a CGI-like command query or log transmission. To reduce the network impact, the MCP agent keeps connection alive and open as much as possible. A subsequent request uses an existing open connection. If the connection breaks, all SSL connections to the same host benefit from session ID cache that drastically reduces re-connection time.
