+# MCPHub Coding Instructions
+
+**ALWAYS follow these instructions first and only fallback to additional search and context gathering if the information here is incomplete or found to be in error.**
+
+## Project Overview
+
+MCPHub is a TypeScript/Node.js MCP (Model Context Protocol) server management hub that provides unified access through HTTP endpoints. It serves as a centralized dashboard for managing multiple MCP servers with real-time monitoring, authentication, and flexible routing.
+
+**Core Components:**
+
+- **Backend**: Express.js + TypeScript + ESM (`src/server.ts`)
+- **Frontend**: React/Vite + Tailwind CSS (`frontend/`)
+- **MCP Integration**: Connects multiple MCP servers (`src/services/mcpService.ts`)
+- **Authentication**: JWT-based with bcrypt password hashing
+- **Configuration**: JSON-based MCP server definitions (`mcp_settings.json`)
+- **Documentation**: API docs and usage instructions(`docs/`)
+
+## Working Effectively
+
+### Bootstrap and Setup (CRITICAL - Follow Exact Steps)
+
+```bash
+# Install pnpm if not available
+npm install -g pnpm
+
+# Install dependencies - takes ~30 seconds
+pnpm install
+
+# Setup environment (optional)
+cp .env.example .env
+
+# Build and test to verify setup
+pnpm lint                    # ~3 seconds - NEVER CANCEL
+pnpm backend:build          # ~5 seconds - NEVER CANCEL
+pnpm test:ci                # ~16 seconds - NEVER CANCEL. Set timeout to 60+ seconds
+pnpm frontend:build         # ~5 seconds - NEVER CANCEL
+pnpm build                  # ~10 seconds total - NEVER CANCEL. Set timeout to 60+ seconds
+```
+
+**CRITICAL TIMING**: These commands are fast but NEVER CANCEL them. Always wait for completion.
+
+### Development Environment
+
+```bash
+# Start both backend and frontend (recommended for most development)
+pnpm dev                    # Backend on :3001, Frontend on :5173
+
+# OR start separately (required on Windows, optional on Linux/macOS)
+# Terminal 1: Backend only
+pnpm backend:dev            # Runs on port 3000 (or PORT env var)
+
+# Terminal 2: Frontend only
+pnpm frontend:dev           # Runs on port 5173, proxies API to backend
+```
+
+**NEVER CANCEL**: Development servers may take 10-15 seconds to fully initialize all MCP servers.
+
+### Build Commands (Production)
+
+```bash
+# Full production build - takes ~10 seconds total
+pnpm build                  # NEVER CANCEL - Set timeout to 60+ seconds
+
+# Individual builds
+pnpm backend:build          # TypeScript compilation - ~5 seconds
+pnpm frontend:build         # Vite build - ~5 seconds
+
+# Start production server
+pnpm start                  # Requires dist/ and frontend/dist/ to exist
+```
+
+### Testing and Validation
+
+```bash
+# Run all tests - takes ~16 seconds with 73 tests
+pnpm test:ci                # NEVER CANCEL - Set timeout to 60+ seconds
+
+# Development testing
+pnpm test                   # Interactive mode
+pnpm test:watch             # Watch mode for development
+pnpm test:coverage          # With coverage report
+
+# Code quality
+pnpm lint                   # ESLint - ~3 seconds
+pnpm format                 # Prettier formatting - ~3 seconds
+```
+
+**CRITICAL**: All tests MUST pass before committing. Do not modify tests to make them pass unless specifically required for your changes.
+
+## Manual Validation Requirements
+
+**ALWAYS perform these validation steps after making changes:**
+
+### 1. Basic Application Functionality
+
+```bash
+# Start the application
+pnpm dev
+
+# Verify backend responds (in another terminal)
+curl http://localhost:3000/api/health
+# Expected: Should return health status
+
+# Verify frontend serves
+curl -I http://localhost:3000/
+# Expected: HTTP 200 OK with HTML content
+```
+
+### 2. MCP Server Integration Test
+
+```bash
+# Check MCP servers are loading (look for log messages)
+# Expected log output should include:
+# - "Successfully connected client for server: [name]"
+# - "Successfully listed [N] tools for server: [name]"
+# - Some servers may fail due to missing API keys (normal in dev)
+```
+
+### 3. Build Verification
+
+```bash
+# Verify production build works
+pnpm build
+node scripts/verify-dist.js
+# Expected: "✅ Verification passed! Frontend and backend dist files are present."
+```
+
+**NEVER skip these validation steps**. If any fail, debug and fix before proceeding.
+
+## Project Structure and Key Files
+
+### Critical Backend Files
+
+- `src/index.ts` - Application entry point
+- `src/server.ts` - Express server setup and middleware
+- `src/services/mcpService.ts` - **Core MCP server management logic**

+- **Frontend feature**: Start from `frontend/src/pages/` or `frontend/src/components/`
+- **Add tests**: Follow patterns in `tests/` directory
+
+### Common Development Tasks
+
+#### Adding a new MCP server:
+
+1. Add server definition to `mcp_settings.json`
+2. Restart backend to load new server
+3. Check logs for successful connection
+4. Test via dashboard or API endpoints
+
+#### API development:
+

+1. Create/modify components in `frontend/src/components/`
+2. Add pages in `frontend/src/pages/`
+3. Update routing if needed
+4. Test in development mode with `pnpm frontend:dev`
+
+#### Documentation:
+
+1. Update or add docs in `docs/` folder
+2. Ensure README.md reflects any major changes
+
+## Validation and CI Requirements
+
+### Before Committing - ALWAYS Run:
+
+```bash
+pnpm lint                   # Must pass - ~3 seconds
+pnpm backend:build          # Must compile - ~5 seconds
+pnpm test:ci                # All tests must pass - ~16 seconds
+pnpm build                  # Full build must work - ~10 seconds
+```
+
+**CRITICAL**: CI will fail if any of these commands fail. Fix issues locally first.
+
+### CI Pipeline (.github/workflows/ci.yml)
+
+- Runs on Node.js 20.x
+- Tests: linting, type checking, unit tests with coverage
+- **NEVER CANCEL**: CI builds may take 2-3 minutes total
+
+## Troubleshooting
+
+### Common Issues
+
+- **"uvx command not found"**: Some MCP servers require `uvx` (Python package manager) - this is expected in development
+- **Port already in use**: Change PORT environment variable or kill existing processes
+- **Frontend not loading**: Ensure frontend was built with `pnpm frontend:build`
+- **MCP server connection failed**: Check server command/args in `mcp_settings.json`
+
+### Build Failures
+
+- **TypeScript errors**: Run `pnpm backend:build` to see compilation errors
+- **Test failures**: Run `pnpm test:verbose` for detailed test output
+- **Lint errors**: Run `pnpm lint` and fix reported issues
+
+### Development Issues
+
+- **Backend not starting**: Check for port conflicts, verify `mcp_settings.json` syntax
+- **Frontend proxy errors**: Ensure backend is running before starting frontend
+- **Hot reload not working**: Restart development server
+
+## Performance Notes
+
+- **Install time**: pnpm install takes ~30 seconds
+- **Build time**: Full build takes ~10 seconds
+- **Test time**: Complete test suite takes ~16 seconds
+- **Startup time**: Backend initialization takes 10-15 seconds (MCP server connections)
+
+**Remember**: NEVER CANCEL any build or test commands. Always wait for completion even if they seem slow.

- `dist/` - Backend build output (TypeScript compilation)
- `frontend/dist/` - Frontend build output (Vite bundle)
- `coverage/` - Test coverage reports
- **Never edit these manually**
-
-### Localization
-
- Translations sit in `locales/` (en.json, fr.json, tr.json, zh.json)
- Frontend uses react-i18next
-
-### Docker and Deployment
-
- `Dockerfile` - Multi-stage build with Python base + Node.js
- `entrypoint.sh` - Docker startup script
- `bin/cli.js` - NPM package CLI entry point
+- Backend services live in `src`, grouped by responsibility (`controllers/`, `services/`, `dao/`, `routes/`, `utils/`), with `server.ts` orchestrating HTTP bootstrap.
+- `frontend/src` contains the Vite + React dashboard; `frontend/public` hosts static assets and translations sit in `locales/`.
+- Jest-aware test code is split between colocated specs (`src/**/*.{test,spec}.ts`) and higher-level suites in `tests/`; use `tests/utils/` helpers when exercising the CLI or SSE flows.
+- Build artifacts and bundles are generated into `dist/`, `frontend/dist/`, and `coverage/`; never edit these manually.

 ## Build, Test, and Development Commands

-### Development Environment
-
-```bash
-# Start both backend and frontend (recommended for most development)
-pnpm dev                    # Backend on :3001, Frontend on :5173
-
-# OR start separately (required on Windows, optional on Linux/macOS)
-# Terminal 1: Backend only
-pnpm backend:dev            # Runs on port 3000 (or PORT env var)
-
-# Terminal 2: Frontend only
-pnpm frontend:dev           # Runs on port 5173, proxies API to backend
-
-# Frontend preview (production build)
-pnpm frontend:preview       # Preview production build
-```
-
-**NEVER CANCEL**: Development servers may take 10-15 seconds to fully initialize all MCP servers.
-
-### Production Build
-
-```bash
-# Full production build - takes ~10 seconds total
-pnpm build                  # NEVER CANCEL - Set timeout to 60+ seconds
-
-# Individual builds
-pnpm backend:build          # TypeScript compilation to dist/ - ~5 seconds
-pnpm frontend:build         # Vite build to frontend/dist/ - ~5 seconds
-
-# Start production server
-pnpm start                  # Requires dist/ and frontend/dist/ to exist
-```
-
-Run `pnpm build` before release or publishing.
-
-### Testing and Validation
-
-```bash
-# Run all tests - takes ~16 seconds with 73 tests
-pnpm test:ci                # NEVER CANCEL - Set timeout to 60+ seconds
-
-# Development testing
-pnpm test                   # Interactive mode
-pnpm test:watch             # Watch mode for development
-pnpm test:coverage          # With coverage report
-
-# Code quality
-pnpm lint                   # ESLint - ~3 seconds
-pnpm format                 # Prettier formatting - ~3 seconds
-```
-
-**CRITICAL**: All tests MUST pass before committing. Do not modify tests to make them pass unless specifically required for your changes.

- **Install time**: pnpm install takes ~30 seconds
- **Build time**: Full build takes ~10 seconds
- **Test time**: Complete test suite takes ~16 seconds
- **Startup time**: Backend initialization takes 10-15 seconds (MCP server connections)
+- `pnpm dev` runs backend (`tsx watch src/index.ts`) and frontend (`vite`) together for local iteration.
+- `pnpm backend:dev`, `pnpm frontend:dev`, and `pnpm frontend:preview` target each surface independently; prefer them when debugging one stack.
+- `pnpm build` executes `pnpm backend:build` (TypeScript to `dist/`) and `pnpm frontend:build`; run before release or publishing.
+- `pnpm test`, `pnpm test:watch`, and `pnpm test:coverage` drive Jest; `pnpm lint` and `pnpm format` enforce style via ESLint and Prettier.

 ## Coding Style & Naming Conventions

- **TypeScript everywhere**: Default to 2-space indentation and single quotes, letting Prettier settle formatting
- **ESM modules**: Always use `.js` extensions in imports, not `.ts` (e.g., `import { something } from './file.js'`)
- **English only**: All code comments must be written in English
- **TypeScript strict**: Follow strict type checking rules
- **Naming conventions**:
-  - Services and data access layers: Use suffixes (`UserService`, `AuthDao`)
-  - React components and files: `PascalCase`
-  - Utility modules: `camelCase`
- **Types and DTOs**: Keep in `src/types` to avoid duplication; re-export through index files only when it clarifies imports
- **ESLint configuration**: Assumes ES modules

 ## Commit & Pull Request Guidelines

 - Follow the existing Conventional Commit pattern (`feat:`, `fix:`, `chore:`, etc.) with imperative, present-tense summaries and optional multi-line context.
 - Each PR should describe the behavior change, list testing performed, and link issues; include before/after screenshots or GIFs for frontend tweaks.
 - Re-run `pnpm build` and `pnpm test` before requesting review, and ensure generated artifacts stay out of the diff.

 ### Common Pitfalls

 - Forgetting migration script → fields won't migrate to DB
 - Optional fields need `nullable: true` in entity
 - Complex objects need `simple-json` column type

-## Auto-Evolution Guidelines for AI Agents
-
-**This section provides guidelines for AI agents to automatically maintain and improve this document.**
-
-### When to Update AGENTS.md
-
-AI agents MUST update this document in the following situations:
-
-#### 1. Code-Documentation Mismatch Detected
-
-When executing tasks, if you discover that:
-
- The actual code structure differs from descriptions in this document
- File paths, imports, or module organization has changed
- New critical files or directories exist that aren't documented
- Documented files or patterns no longer exist
-
-**Action**: Immediately update the relevant section to reflect the current codebase state.
-
-**Example scenarios**:
-
- A controller is now in `src/api/controllers/` instead of `src/controllers/`
- New middleware files exist that should be documented
- The DAO implementation has been refactored with a different structure
- Build output directories have changed
-
-#### 2. User Preferences and Requirements
-
-During conversation, if the user expresses:
-
- **Coding preferences**: Indentation style, naming conventions, code organization patterns
- **Workflow requirements**: Required validation steps, commit procedures, testing expectations
- **Tool preferences**: Preferred libraries, frameworks, or development tools
- **Quality standards**: Code review criteria, documentation requirements, error handling patterns
- **Development principles**: Architecture decisions, design patterns, best practices
-
-**Action**: Add or update the relevant section to capture these preferences for future reference.
-
-**Example scenarios**:
-
- User prefers async/await over promises → Update coding style section
- User requires specific test coverage thresholds → Update testing guidelines
- User has strong opinions about error handling → Add to development process section
- User establishes new deployment procedures → Update deployment section
-
-### How to Update AGENTS.md
-
-1. **Identify the Section**: Determine which section needs updating based on the type of change
-2. **Make Precise Changes**: Update only the relevant content, maintaining the document structure
-3. **Preserve Format**: Keep the existing markdown formatting and organization
-4. **Add Context**: If adding new content, ensure it fits logically within existing sections
-5. **Verify Accuracy**: After updating, ensure the new information is accurate and complete
-
-### Update Principles
-
- **Accuracy First**: Documentation must reflect the actual current state
- **Clarity**: Use clear, concise language; avoid ambiguity
- **Completeness**: Include sufficient detail for agents to work effectively
- **Consistency**: Maintain consistent terminology and formatting throughout
- **Actionability**: Focus on concrete, actionable guidance rather than vague descriptions
-
-### Self-Correction Process
-
-Before completing any task:
-
-1. Review relevant sections of AGENTS.md
-2. During execution, note any discrepancies between documentation and reality
-3. Update AGENTS.md to correct discrepancies
-4. Verify the update doesn't conflict with other sections
-5. Proceed with the original task using the updated information
-
-### Meta-Update Rule
-
-If this auto-evolution section itself needs improvement based on experience:
-
- Update it to better serve future agents
- Add new scenarios or principles as they emerge
- Refine the update process based on what works well
-
-**Remember**: This document is a living guide. Keeping it accurate and current is as important as following it.

+# 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
+}
+```

+
+## 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.
+

-title: 'Output Compression'
-description: 'Reduce token consumption by compressing MCP tool outputs'
---
-
-# Output Compression
-
-MCPHub provides an AI-powered compression mechanism to reduce token consumption from MCP tool outputs. This feature is particularly useful when dealing with large outputs that can significantly impact system efficiency and scalability.
-
-## Overview
-
-The compression feature uses a lightweight AI model (by default, `gpt-4o-mini`) to intelligently compress MCP tool outputs while preserving all essential information. This can help:
-
- **Reduce token overhead** by compressing verbose tool information
- **Lower operational costs** associated with token consumption
- **Improve performance** for downstream processing
- **Better resource utilization** in resource-constrained environments
-
-## Configuration
-
-Add the compression configuration to your `systemConfig` section in `mcp_settings.json`:
-
-```json
-{
-  "systemConfig": {
-    "compression": {
-      "enabled": true,
-      "model": "gpt-4o-mini",
-      "maxInputTokens": 100000,
-      "targetReductionRatio": 0.5
-    }
-  }
-}
-```
-
-### Configuration Options
-
-| Option | Type | Default | Description |
-|--------|------|---------|-------------|
-| `enabled` | boolean | `false` | Enable or disable output compression |
-| `model` | string | `"gpt-4o-mini"` | AI model to use for compression |
-| `maxInputTokens` | number | `100000` | Maximum input tokens for compression |
-| `targetReductionRatio` | number | `0.5` | Target size reduction ratio (0.0-1.0) |
-
-## Requirements
-
-Output compression requires:
-
-1. An OpenAI API key configured in the smart routing settings
-2. The compression feature must be explicitly enabled
-
-### Setting up OpenAI API Key
-
-Configure your OpenAI API key using environment variables or system configuration:
-
-**Environment Variable:**
-```bash
-export OPENAI_API_KEY=your-api-key
-```
-
-**Or in systemConfig:**
-```json
-{
-  "systemConfig": {
-    "smartRouting": {
-      "openaiApiKey": "your-api-key",
-      "openaiApiBaseUrl": "https://api.openai.com/v1"
-    }
-  }
-}
-```
-
-## How It Works
-
-1. **Content Size Check**: When a tool call completes, the compression service checks if the output is large enough to benefit from compression (threshold is 10% of `maxInputTokens` or 1000 tokens, whichever is smaller)
-
-2. **AI Compression**: If the content exceeds the threshold, it's sent to the configured AI model with instructions to compress while preserving essential information
-
-3. **Size Validation**: The compressed result is compared with the original; if compression didn't reduce the size, the original content is used
-
-4. **Error Handling**: If compression fails for any reason, the original content is returned unchanged
-
-## Fallback Mechanism
-
-The compression feature includes graceful degradation for several scenarios:
-
- **Compression disabled**: Original content is returned
- **No API key**: Original content is returned with a warning
- **Small content**: Content below threshold is not compressed
- **API errors**: Original content is returned on any API failure
- **Error responses**: Tool error responses are never compressed
- **Non-text content**: Images and other media types are preserved as-is
-
-## Best Practices
-
-1. **Start with defaults**: The default configuration provides a good balance between compression and quality
-
-2. **Monitor results**: Review compressed outputs to ensure important information isn't lost
-
-3. **Adjust threshold**: If you have consistently large outputs, consider lowering `targetReductionRatio` for more aggressive compression
-
-4. **Use efficient models**: The default `gpt-4o-mini` provides a good balance of cost and quality; switch to `gpt-4o` if you need higher quality compression
-
-## Limitations
-
- Compression adds latency due to the AI API call
- API costs apply for each compression operation
- Very short outputs won't be compressed (below threshold)
- Binary/non-text content is not compressed

+# 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
