WalkthroughThis PR adds per-transport ping control flags (ssePingEnabled and streamPingEnabled) to MCPConfig, enabling selective enabling/disabling of server pings for SSE and stream protocols, with guards and error handling around ping invocations in MCPControllerRegister. Changes

Code Review
This pull request introduces configuration options to enable or disable pinging for SSE and stream connections, which is a useful feature for managing connection health. The implementation is generally sound, but I have identified a couple of areas for improvement. Specifically, there's a design issue in MCPConfig.ts where per-server configurations do not fall back to the global configuration, making it less intuitive. I've also suggested a minor enhancement to logging in MCPControllerRegister.ts to provide more context for easier debugging. Overall, good work on adding this functionality.

11-12: LGTM! Test configuration aligns with new ping control flags.The addition of
ssePingEnabledandstreamPingEnabledflags to the test fixture configuration properly exercises the new per-transport ping control functionality.plugin/controller/lib/impl/mcp/MCPControllerRegister.ts (2)
347-349: LGTM! Ping invocations properly gated by feature flags.The conditional execution of
mcpServerPingbased ongetStreamPingEnabled(name)andgetSsePingEnabled(name)correctly implements per-transport ping control, preventing unnecessary network calls when pings are disabled.Also applies to: 501-503
672-683: LGTM! Robust error handling for ping operations.Wrapping
server.ping()in try/catch/finally ensures:
- Ping failures are logged without crashing the interval
- Duration-based cleanup (clearing the interval) always executes regardless of ping outcome
This is a solid improvement for reliability.
