- Replace getRawBody with direct req.body usage since express.json() middleware already parses it
- Add debugging support with --inspect flag for dev scripts
- Add VS Code launch configurations for debugging
The issue was that getRawBody tried to read an already-consumed stream. Since express.json()
middleware is applied globally, we can directly use req.body instead.

All logs now include contextual information like sessionId, userId, and channel names
for easier debugging and monitoring.

- Add userId: string field to distinguish individual users from OAuth clients
- Prepares for user session isolation implementation
- clientId represents OAuth application, userId represents individual user
This separation allows multiple users to use the same OAuth client while
maintaining session isolation for security.

- Test error handling for invalid session IDs
- Test user session isolation scenarios (documents expected behavior)
- Use MockRedisClient directly instead of mocking the mock

- Implement new ServerRedisTransport for server->client messages using request-specific channels
- Add redisRelayToMcpServer function for dynamic request-id based subscriptions
- Update shttp handler to use new transport return types with cleanup functions
- Remove old relayTransports and helper functions in favor of new architecture
- Add comprehensive test suites for Redis transport and shttp handler components
- Fix linting issues and ensure all tests pass
The new system routes server responses to channels like:
- mcp:shttp:toclient:${sessionId}:${requestId} for request responses
- mcp:shttp:toclient:${sessionId}:__GET_stream for notifications
This enables efficient scaling across multiple shttp instances as each client
only subscribes to channels relevant to their specific requests.
