java.lang.Object

io.jenkins.plugins.mcp.server.McpServerShutdownListener

@Restricted(org.kohsuke.accmod.restrictions.NoExternalUse.class)
@Extension
public class McpServerShutdownListener
extends Object

Listens for Jenkins shutdown events and notifies MCP clients.

This class hooks into Jenkins' termination lifecycle to update the health endpoint status, allowing connected MCP clients to detect when Jenkins is shutting down and prepare for reconnection.

The shutdown sequence:

1. Jenkins initiates shutdown
2. This terminator is called, setting the health endpoint to "shutting_down" state
3. A grace period allows clients to detect the state change via the health endpoint
4. Jenkins completes shutdown
