* fix: Separate MCP GET SSE body timeout from POST and suppress SDK-internal stream recovery - Add a dedicated GET Agent with a configurable `sseReadTimeout` (default 5 min, matching the Python MCP SDK) so idle SSE streams time out independently of POST requests, preventing the reconnect-loop log flood described in Discussion #11230. - Suppress "SSE stream disconnected" and "Failed to reconnect SSE stream" errors in setupTransportErrorHandlers — these are SDK-internal recovery events, not transport failures. "Maximum reconnection attempts exceeded" still escalates. - Add optional `sseReadTimeout` to BaseOptionsSchema for per-server configuration. - Add 6 tests: agent timeout separation, custom sseReadTimeout, SSE disconnect suppression (3 unit), and a real-server integration test proving the GET stream recovers without a full transport rebuild. * fix: Refactor MCP connection timeouts and error handling - Updated the `DEFAULT_SSE_READ_TIMEOUT` to use a constant for better readability. - Introduced internal error message constants for SSE stream disconnection and reconnection failures to improve maintainability. - Enhanced type safety in tests by ensuring the options symbol is defined before usage. - Updated the `sseReadTimeout` in `BaseOptionsSchema` to enforce positive values, ensuring valid configurations. * chore: Update SSE read timeout documentation format in BaseOptionsSchema - Changed the default timeout value comment in BaseOptionsSchema to use an underscore for better readability, aligning with common formatting practices. |
