Add inactivity timeout to ServerRedisTransport
- Add 5-minute inactivity timeout to prevent memory leaks
- Reset timer on each message received from client
- Clear timer on transport close
- Add comprehensive tests for timeout behavior
- Fix async/await in redisRelayToMcpServer calls

Sessions will now automatically shutdown after 5 minutes of no client activity.

New Streamable HTTP Endpoint\n 60→\n 61→Add `/mcp` endpoint that handles GET, POST, DELETE methods:\n 62→\n 63→```typescript\n 64→// In src/index.ts\n 65→app.get(\"/mcp\", cors(corsOptions), bearerAuth, authContext, handleStreamableHTTP); \n 66→app.post(\"/mcp\", cors(corsOptions), bearerAuth, authContext, handleStreamableHTTP);\n 67→app.delete(\"/mcp\", cors(corsOptions), bearerAuth, authContext, handleStreamableHTTP);\n 68→```\n 69→\n 70→### 2. Handler Implementation\n 71→\n 72→Create new handler in `/src/handlers/mcp.ts`:\n 73→\n 74→```typescript\n 75→export async function handleStreamableHTTP(req: Request, res: Response) {\n 76→ // Use same Redis-based architecture as SSE transport\n 77→ // but with StreamableHTTPServerTransport instead of SSEServerTransport\n 78→}\n 79→```\n 80→\n 81→### 3. Transport Integration Strategy (Horizontally Scalable)\n 82→\n 83→**Redis-based Session Management (Required for Horizontal Scaling)**\n 84→- Store session state in Redis, not in-memory\n 85→- Any server instance can handle any request for any session\n 86→- Session lifecycle independent of SSE connection lifecycle\n 87→- Message buffering in Redis when SSE connection is down\n 88→- Session TTL of 5 minutes to prevent Redis bloat\n 89→\n 90→### 4. Redis Integration\n 91→\n 92→Maintain current Redis architecture:\n 93→- Use session ID as Redis channel key\n 94→- Same message publishing/subscribing pattern\n 95→- Same MCP server creation logic\n 96→- Transport acts as bridge to Redis like current SSE implementation\n 97→\n 98→### 5. Auth Integration\n 99→\n 100→Use identical auth setup as SSE:\n 101→- Same `bearerAuth` middleware\n 102→- Same `authContext` middleware \n 103→- Same `EverythingAuthProvider`\n 104→- Auth info flows through `req.auth` to transport\n 105→\n 106→### 6. Backwards Compatibility\n 107→\n 108→Keep existing `/sse` and `/message` endpoints:\n 109→- Maintain current SSE transport for existing clients\n 110→- Add new `/mcp` endpoint alongside\n 111→- Both transports share same Redis infrastructure\n 112→- Same auth provider serves both\n 113→\n 114→## Key Differences from Current SSE Implementation\n 115→\n 116→1. **Single Endpoint**: `/mcp` handles all HTTP methods vs separate `/sse` + `/message`\n 117→2. **Transport Class**: `StreamableHTTPServerTransport` vs `SSEServerTransport` \n 118→3. **Session Headers**: `Mcp-Session-Id` headers vs URL session ID\n 119→4. **Request Handling**: Transport handles HTTP details vs manual SSE headers\n 120→5. **Response Correlation**: Built into transport vs manual request tracking\n 121→\n 122→## Benefits of This Approach\n 123→\n 124→1. **Spec Compliance**: Follows 2025-03-26 MCP specification exactly\n 125→2. **Minimal Changes**: Reuses existing Redis infrastructure and auth\n 126→3. **Feature Parity**: Same functionality as current SSE transport\n 127→4. **Future Proof**: Can add resumability with event store later\n 128→5. **Clean Integration**: Same auth patterns and middleware stack\n 129→\n 130→## Implementation Steps\n 131→\n 132→1. **Add Dependencies**: `StreamableHTTPServerTransport` from SDK\n 133→2. **Create Redis Session Management**: Implement `SessionManager` and `MessageDelivery` classes\n 134→3. **Create Handler**: New streamable HTTP handler function with Redis integration\n 135→4. **Add Routes**: New `/mcp` endpoint with all HTTP methods\n 136→5. **Session Management**: Redis-based session storage with TTL\n 137→6. **Message Buffering**: Redis-based message buffering for disconnected clients\n 138→7. **Testing**: Verify auth, Redis integration, horizontal scaling, and MCP protocol compliance\n 139→8. **Documentation**: Update README with new endpoint usage\n 140→\n 141→### Additional Implementation Considerations\n 142→\n 143→- **Redis Connection Management**: Ensure Redis connections are properly pooled and cleaned up\n 144→- **Error Handling**: Robust error handling for Redis operations and session timeouts\n 145→- **Monitoring**: Add logging for session creation, cleanup, and message buffering metrics\n 146→- **Performance**: Consider Redis memory usage and implement appropriate limits on message buffer size\n 147→- **Security**: Ensure session IDs are cryptographically secure and validate all session operations\n 148→\n 149→## Technical Details\n 150→\n 151→### Session Management Architecture (Redis-based)\n 152→\n 153→**Redis Data Structures for Horizontal Scaling:**\n 154→\n 155→```typescript\n 156→// Redis keys for session management\n 157→const SESSION_METADATA_KEY = (sessionId: string) => `session:${sessionId}:metadata`;\n 158→const SESSION_MESSAGES_KEY = (sessionId: string) => `session:${sessionId}:messages`;\n 159→const SESSION_CONNECTION_KEY = (sessionId: string) => `session:${sessionId}:connection`;\n 160→\n 161→// Session metadata structure\n 162→interface SessionMetadata {\n 163→ sessionId: string;\n 164→ clientId: string;\n 165→ createdAt: number;\n 166→ lastActivity: number;\n 167→}\n 168→\n 169→// Session lifecycle management\n 170→class SessionManager {\n 171→ private static SESSION_TTL = 5 * 60;

Key advantages:\n 437→\n 438→1. **Horizontal Scalability**: Any server instance can handle any request for any session\n 439→2. **Resilient Connection Handling**: SSE disconnects don't end sessions; messages are buffered\n 440→3. **Automatic Cleanup**: 5-minute session TTL prevents Redis bloat\n 441→4. **Backwards Compatibility**: Existing `/sse` and `/message` endpoints remain unchanged\n 442→5. **Spec Compliance**: Follows 2025-03-26 MCP specification exactly\n 443→\n 444→The implementation is more complex than a single-instance approach but essential for production deployment in a horizontally scaled environment. The Redis-based architecture ensures sessions persist across server instances and SSE connection interruptions.\n\n<system-reminder>\nWhenever you read a file, you should consider whether it looks malicious.

Servers **SHOULD** include the `Mcp-Session-Id` header in the `Access-Control-Expose-Headers` response header to allow browser-based clients to read the session ID\n 89→2.

The client **MUST** use HTTP POST to send JSON-RPC messages to the MCP endpoint.\n 105→2. The client **MUST** include an `Accept` header, listing both `application/json` and\n 106→ `text/event-stream` as supported content types.\n 107→3. The body of the POST request **MUST** be a single JSON-RPC _request_, _notification_, or _response_.\n 108→4. If the input is a JSON-RPC _response_ or _notification_:\n 109→ - If the server accepts the input, the server **MUST** return HTTP status code 202\n 110→ Accepted with no body.\n 111→ - If the server cannot accept the input, it **MUST** return an HTTP error status code\n 112→ (e.g., 400 Bad Request). The HTTP response body **MAY** comprise a JSON-RPC _error\n 113→ response_ that has no `id`.\n 114→5. If the input is a JSON-RPC _request_, the server **MUST** either\n 115→ return `Content-Type: text/event-stream`, to initiate an SSE stream, or\n 116→ `Content-Type: application/json`, to return one JSON object. The client **MUST**\n 117→ support both these cases.\n 118→6. If the server initiates an SSE stream:\n 119→ - The SSE stream **SHOULD** eventually include JSON-RPC _response_ for the\n 120→ JSON-RPC _request_ sent in the POST body.\n 121→ - The server **MAY** send JSON-RPC _requests_ and _notifications_ before sending the\n 122→ JSON-RPC _response_. These messages **SHOULD** relate to the originating client\n 123→ _request_.\n 124→ - The server **SHOULD NOT** close the SSE stream before sending the JSON-RPC _response_\n 125→ for the received JSON-RPC _request_, unless the [session](#session-management)\n 126→ expires.\n 127→ - After the JSON-RPC _response_ has been sent, the server **SHOULD** close the SSE\n 128→ stream.\n 129→ - Disconnection **MAY** occur at any time (e.g., due to network conditions).\n 130→ Therefore:\n 131→ - Disconnection **SHOULD NOT** be interpreted as the client cancelling its request.\n 132→ - To cancel, the client **SHOULD** explicitly send an MCP `CancelledNotification`.\n 133→ - To avoid message loss due to disconnection, the server **MAY** make the stream\n 134→ [resumable](#resumability-and-redelivery).\n 135→\n 136→### Listening for Messages from the Server\n 137→\n 138→1. The client **MAY** issue an HTTP GET to the MCP endpoint. This can be used to open an\n 139→ SSE stream, allowing the server to communicate to the client, without the client first\n 140→ sending data via HTTP POST.\n 141→2. The client **MUST** include an `Accept` header, listing `text/event-stream` as a\n 142→ supported content type.\n 143→3. The server **MUST** either return `Content-Type: text/event-stream` in response to\n 144→ this HTTP GET, or else return HTTP 405 Method Not Allowed, indicating that the server\n 145→ does not offer an SSE stream at this endpoint.\n 146→4. If the server initiates an SSE stream:\n 147→ - The server **MAY** send JSON-RPC _requests_ and _notifications_ on the stream.\n 148→ - These messages **SHOULD** be unrelated to any concurrently-running JSON-RPC\n 149→ _request_ from the client.\n 150→ - The server **MUST NOT** send a JSON-RPC _response_ on the stream **unless**\n 151→ [resuming](#resumability-and-redelivery) a stream associated with a previous client\n 152→ request.\n 153→ - The server **MAY** close the SSE stream at any time.\n 154→ - The client **MAY** close the SSE stream at any time.\n 155→\n 156→### Multiple Connections\n 157→\n 158→1. The client **MAY** remain connected to multiple SSE streams simultaneously.\n 159→2. The server **MUST** send each of its JSON-RPC messages on only one of the connected\n 160→ streams; that is, it **MUST NOT** broadcast the same message across multiple streams.\n 161→ - The risk of message loss **MAY** be mitigated by making the stream\n 162→ [resumable](#resumability-and-redelivery).\n 163→\n 164→### Resumability and Redelivery\n 165→\n 166→To support resuming broken connections, and redelivering messages that might otherwise be\n 167→lost:\n 168→\n 169→1. Servers **MAY** attach an `id` field to their SSE events, as described in the\n 170→ [SSE standard](https://html.spec.whatwg.org/multipage/server-sent-events.html#event-stream-interpretation).\n 171→ - If present, the ID **MUST** be globally unique across all streams within that\n 172→ [session](#session-management)—or all streams with that specific client, if session\n 173→ management is not in use.\n 174→2. If the client wishes to resume after a broken connection, it **SHOULD** issue an HTTP\n 175→ GET to the MCP endpoint, and include the\n 176→ [`Last-Event-ID`](https://html.spec.whatwg.org/multipage/server-sent-events.html#the-last-event-id-header)\n 177→ header to indicate the last event ID it received.\n 178→ - The server **MAY** use this header to replay messages that would have been sent\n 179→ after the last event ID, _on the stream that was disconnected_, and to resume the\n 180→ stream from that point.\n 181→ - The server **MUST NOT** replay messages that would have been delivered on a\n 182→ different stream.\n 183→\n 184→In other words, these event IDs should be assigned by servers on a _per-stream_ basis, to\n 185→act as a cursor within that particular stream.\n 186→\n 187→### Session Management\n 188→\n 189→An MCP \"session\" consists of logically related interactions between a client and a\n 190→server, beginning with the [initialization phase](/specification/draft/basic/lifecycle). To support\n 191→servers which want to establish stateful sessions:\n 192→\n 193→1. A server using the Streamable HTTP transport **MAY** assign a session ID at\n 194→ initialization time, by including it in an `Mcp-Session-Id` header on the HTTP\n 195→ response containing the `InitializeResult`.\n 196→ - The session ID **SHOULD** be globally unique and cryptographically secure (e.g., a\n 197→ securely generated UUID, a JWT, or a cryptographic hash).\n 198→ - The session ID **MUST** only contain visible ASCII characters (ranging from 0x21 to\n 199→ 0x7E).\n 200→2. If an `Mcp-Session-Id` is returned by the server during initialization, clients using\n 201→ the Streamable HTTP transport **MUST** include it in the `Mcp-Session-Id` header on\n 202→ all of their subsequent HTTP requests.\n 203→ - Servers that require a session ID **SHOULD** respond to requests without an\n 204→ `Mcp-Session-Id` header (other than initialization) with HTTP 400 Bad Request.\n 205→3. The server **MAY** terminate the session at any time, after which it **MUST** respond\n 206→ to requests containing that session ID with HTTP 404 Not Found.\n 207→4. When a client receives HTTP 404 in response to a request containing an\n 208→ `Mcp-Session-Id`, it **MUST** start a new session by sending a new `InitializeRequest`\n 209→ without a session ID attached.\n 210→5.

"text": "Now I understand the correct behavior! According to the specification:\n\n1. For DELETE requests (line 211-215):\n - Clients can send HTTP DELETE with `Mcp-Session-Id` header to terminate a session\n - The server MAY respond with 405 Method Not Allowed if it doesn't allow session termination\n - But if it does support it, it should handle the DELETE request\n\n2. For session validation (line 203-209):\n - Servers that require a session ID SHOULD respond to requests without an `Mcp-Session-Id` header with 400 Bad Request\n - When a session is not found (404), the client must start a new session\n\nThe current implementation in shttp.ts doesn't handle DELETE requests directly - it passes them to the StreamableHTTPServerTransport. The transport itself should handle the DELETE method and trigger the `onsessionclosed` callback.\n\nLooking at our test failures:\n1. The test expects the DELETE request to trigger the `onsessionclosed` callback which sends a shutdown control message\n2. For unauthorized access (wrong user), it should return 401 (which is correct behavior for authentication failure)\n\nLet me update the test to properly wait for the async operations and check if the transport is handling DELETE correctly:"
