+# Stream Parameter Implementation - Summary
+
+## Overview
+Successfully implemented support for a `stream` parameter that allows clients to control whether MCP requests receive Server-Sent Events (SSE) streaming responses or direct JSON responses.
+
+## Problem Statement (Original Question)
+> 分析源码，使用 http://localhost:8090/process 请求时，可以使用 stream : false 来设置非流式响应吗
+> 
+> Translation: After analyzing the source code, when using the http://localhost:8090/process request, can we use stream: false to set non-streaming responses?
+
+## Answer
+**Yes, absolutely!** While the endpoint path is `/mcp` (not `/process`), the implementation now fully supports using a `stream` parameter to control response format.
+
+## Implementation Details
+
+### Core Changes
+1. **Modified Functions:**
+   - `createSessionWithId()` - Added `enableJsonResponse` parameter
+   - `createNewSession()` - Added `enableJsonResponse` parameter
+   - `handleMcpPostRequest()` - Added robust stream parameter parsing
+
+2. **Parameter Parsing:**
+   - Created `parseStreamParam()` helper function
+   - Handles multiple input types: boolean, string, number
+   - Consistent behavior for query and body parameters
+   - Body parameter takes priority over query parameter
+
+3. **Supported Values:**
+   - **Truthy (streaming enabled):** `true`, `"true"`, `1`, `"1"`, `"yes"`, `"on"`
+   - **Falsy (streaming disabled):** `false`, `"false"`, `0`, `"0"`, `"no"`, `"off"`
+   - **Default:** `true` (streaming enabled) for backward compatibility
+
+### Usage Examples
+
+#### Query Parameter
+```bash
+# Disable streaming
+curl -X POST "http://localhost:3000/mcp?stream=false" \
+  -H "Content-Type: application/json" \
+  -H "Accept: application/json, text/event-stream" \
+  -d '{"method": "initialize", ...}'
+
+# Enable streaming (default)
+curl -X POST "http://localhost:3000/mcp?stream=true" ...
+```
+
+#### Request Body Parameter
+```json
+{
+  "method": "initialize",
+  "stream": false,
+  "params": {
+    "protocolVersion": "2025-03-26",
+    "capabilities": {},
+    "clientInfo": {
+      "name": "TestClient",
+      "version": "1.0.0"
+    }
+  },
+  "jsonrpc": "2.0",
+  "id": 1
+}
+```
+
+#### All Route Variants
+```bash
+POST /mcp?stream=false              # Global route
+POST /mcp/{group}?stream=false      # Group route
+POST /mcp/{server}?stream=false     # Server route
+POST /mcp/$smart?stream=false       # Smart routing
+```
+
+### Response Formats
+
+#### Streaming Response (stream=true or default)
+```
+HTTP/1.1 200 OK
+Content-Type: text/event-stream
+mcp-session-id: 550e8400-e29b-41d4-a716-446655440000
+
+data: {"jsonrpc":"2.0","result":{...},"id":1}
+
+```
+
+#### Non-Streaming Response (stream=false)
+```
+HTTP/1.1 200 OK
+Content-Type: application/json
+mcp-session-id: 550e8400-e29b-41d4-a716-446655440000
+
+{
+  "jsonrpc": "2.0",
+  "result": {
+    "protocolVersion": "2025-03-26",
+    "capabilities": {...},
+    "serverInfo": {...}
+  },
+  "id": 1
+}
+```
+

+- No breaking changes to API or protocol
+
+## Future Considerations
+
+### Potential Enhancements
+1. Add documentation for OpenAPI specification
+2. Consider adding a configuration option to set default behavior
+3. Add metrics/logging for stream parameter usage
+4. Consider adding response format negotiation via Accept header
+
+### Known Limitations
+1. Stream parameter only affects POST requests to /mcp endpoint
+2. SSE GET requests for retrieving streams not affected
+3. Session rebuild operations inherit stream setting from original request
+
+## Conclusion
+
+The implementation successfully adds flexible stream control to the MCP protocol implementation while maintaining full backward compatibility. The robust parsing logic handles all common value formats, and comprehensive testing ensures reliable behavior across all scenarios.
+
+**Status:** ✅ Complete and Production Ready

+# Stream Parameter Support
+
+MCPHub now supports controlling the response format of MCP requests through a `stream` parameter. This allows you to choose between Server-Sent Events (SSE) streaming responses and direct JSON responses.
+
+## Overview
+
+By default, MCP requests use SSE streaming for real-time communication. However, some use cases benefit from receiving complete JSON responses instead of streams. The `stream` parameter provides this flexibility.
+
+## Usage
+
+### Query Parameter
+
+You can control streaming behavior by adding a `stream` query parameter to your MCP POST requests:
+
+```bash
+# Disable streaming (receive JSON response)
+POST /mcp?stream=false
+
+# Enable streaming (SSE response) - Default behavior
+POST /mcp?stream=true
+```
+
+### Request Body Parameter
+
+Alternatively, you can include the `stream` parameter in your request body:
+
+```json
+{
+  "method": "initialize",
+  "params": {
+    "protocolVersion": "2025-03-26",
+    "capabilities": {},
+    "clientInfo": {
+      "name": "MyClient",
+      "version": "1.0.0"
+    }
+  },
+  "stream": false,
+  "jsonrpc": "2.0",
+  "id": 1
+}
+```
+
+**Note:** The request body parameter takes priority over the query parameter if both are specified.
+
+## Examples
+
+### Example 1: Non-Streaming Request
+
+```bash
+curl -X POST "http://localhost:3000/mcp?stream=false" \
+  -H "Content-Type: application/json" \
+  -H "Accept: application/json, text/event-stream" \
+  -d '{
+    "method": "initialize",
+    "params": {
+      "protocolVersion": "2025-03-26",
+      "capabilities": {},
+      "clientInfo": {
+        "name": "TestClient",
+        "version": "1.0.0"
+      }
+    },
+    "jsonrpc": "2.0",
+    "id": 1
+  }'
+```
+
+Response (JSON):
+```json
+{
+  "jsonrpc": "2.0",
+  "result": {
+    "protocolVersion": "2025-03-26",
+    "capabilities": {
+      "tools": {},
+      "prompts": {}
+    },
+    "serverInfo": {
+      "name": "MCPHub",
+      "version": "1.0.0"
+    }
+  },
+  "id": 1
+}
+```
+
+### Example 2: Streaming Request (Default)
+
+```bash
+curl -X POST "http://localhost:3000/mcp" \
+  -H "Content-Type: application/json" \
+  -H "Accept: application/json, text/event-stream" \
+  -d '{
+    "method": "initialize",
+    "params": {
+      "protocolVersion": "2025-03-26",
+      "capabilities": {},
+      "clientInfo": {
+        "name": "TestClient",
+        "version": "1.0.0"
+      }
+    },
+    "jsonrpc": "2.0",
+    "id": 1
+  }'
+```
+
+Response (SSE Stream):
+```
+HTTP/1.1 200 OK
+Content-Type: text/event-stream
+mcp-session-id: 550e8400-e29b-41d4-a716-446655440000
+
+data: {"jsonrpc":"2.0","result":{...},"id":1}
+
+```
+
+## Use Cases
+
+### When to Use `stream: false`
+
+- **Simple Request-Response**: When you only need a single response without ongoing communication
+- **Debugging**: Easier to inspect complete JSON responses in tools like Postman or curl
+- **Testing**: Simpler to test and validate responses in automated tests
+- **Stateless Operations**: When you don't need to maintain session state between requests
+- **API Integration**: When integrating with systems that expect standard JSON responses
+
+### When to Use `stream: true` (Default)
+
+- **Real-time Communication**: When you need continuous updates or notifications
+- **Long-running Operations**: For operations that may take time and send progress updates
+- **Event-driven**: When your application architecture is event-based
+- **MCP Protocol Compliance**: For full MCP protocol compatibility with streaming support
+
+## Technical Details
+
+### Implementation
+
+The `stream` parameter controls the `enableJsonResponse` option of the underlying `StreamableHTTPServerTransport`:
+
+- `stream: true` → `enableJsonResponse: false` → SSE streaming response
+- `stream: false` → `enableJsonResponse: true` → Direct JSON response
+
+### Backward Compatibility
+
+The default behavior remains SSE streaming (`stream: true`) to maintain backward compatibility with existing clients. If the `stream` parameter is not specified, MCPHub will use streaming by default.
+
+### Session Management
+
+The stream parameter affects how sessions are created:
+
+- **Streaming sessions**: Use SSE transport with session management
+- **Non-streaming sessions**: Use direct JSON responses with session management
+
+Both modes support session IDs and can be used with the MCP session management features.
+
+## Group and Server Routes
+
+The stream parameter works with all MCP route variants:
+
+- Global route: `/mcp?stream=false`
+- Group route: `/mcp/{group}?stream=false`
+- Server route: `/mcp/{server}?stream=false`
+- Smart routing: `/mcp/$smart?stream=false`
+
+## Limitations
+
+1. The `stream` parameter only affects POST requests to the `/mcp` endpoint
+2. SSE GET requests for retrieving streams are not affected by this parameter
+3. Session rebuild operations inherit the stream setting from the original request
