#2 Implement HTTP-based transport for MCP server

Description

Add support for HTTP-based transport in addition to the existing stdio transport. This will allow the MCP server to be accessed over HTTP/HTTPS, making it more flexible for different deployment scenarios.

Requirements

• Implement HTTP server using Express or similar framework
• Support SSE (Server-Sent Events) for streaming responses
• Maintain compatibility with existing stdio transport
• Add configuration options for HTTP mode (port, host, etc.)
• Update documentation with HTTP usage instructions

Implementation Plan

1. Add HTTP transport support alongside stdio
2. Create HTTP endpoints for MCP protocol
3. Add environment configuration for HTTP mode
4. Update Docker setup to support HTTP deployment
5. Document HTTP API usage

Acceptance Criteria

• Server can run in both stdio and HTTP modes
• HTTP endpoints properly implement MCP protocol
• All existing tools work over HTTP transport
• Documentation is updated with examples

Starting implementation of HTTP transport support.

Current Status: Beginning development

Next Steps:

1. Install required dependencies (express, @modelcontextprotocol/sdk)
2. Create HTTP transport module
3. Update main server to support both stdio and HTTP modes

✅ HTTP Transport Implementation Complete

All requirements for HTTP-based transport have been successfully implemented and verified.

Implementation Summary

Completed Components:

1. ✅ HTTP server implementation using Express (src/http-server.ts)
2. ✅ SSE (Server-Sent Events) transport integration via MCP SDK
3. ✅ Dual transport mode support (stdio/http) in main entry point
4. ✅ Environment configuration (TRANSPORT_MODE, HTTP_PORT, HTTP_HOST)
5. ✅ Docker support for HTTP deployment
6. ✅ Comprehensive documentation updates

Technical Details

New Files:

• src/http-server.ts - Express-based HTTP server with SSE transport
• Updated src/index.ts - Added HTTP transport mode selection
• Updated src/server.ts - Extracted server creation logic for reuse

HTTP Endpoints:

• GET /health - Health check endpoint (returns JSON status)
• GET /sse - Server-Sent Events endpoint for MCP protocol
• POST /message - Message endpoint for client requests

Features:

• CORS support for cross-origin requests
• Configurable host and port via environment variables
• All existing MCP tools work seamlessly over HTTP transport
• Maintains full compatibility with stdio transport

Verification Results

Build: ✅ TypeScript compilation successful Runtime: ✅ HTTP server starts and listens correctly Health Check: ✅ Returns proper JSON response SSE Connection: ✅ Establishes SSE transport successfully Docker: ✅ Multi-stage Dockerfile supports HTTP mode

Documentation Updates

README.md:

• Added Issue Management section to Features
• Added complete Issue Management tools documentation
• Updated Transport Modes section with HTTP details
• Added HTTP Mode usage instructions
• Added HTTP Mode with Docker examples

USAGE_EXAMPLES.md:

• Added HTTP Transport setup examples
• Added HTTP endpoint documentation
• Added MCP Client SDK usage examples
• Added HTTP testing examples with curl
• Added CORS support documentation
• Added Issue Management usage examples

Configuration Example

# .env file for HTTP mode
GOGS_SERVER_URL=https://your-gogs-server.com
GOGS_ACCESS_TOKEN=your-access-token
TRANSPORT_MODE=http
HTTP_PORT=3000
HTTP_HOST=0.0.0.0

Dependencies Added

• express@^5.1.0
• cors@^2.8.5
• @types/express@^5.0.5
• @types/cors@^2.8.19

All acceptance criteria have been met. The implementation is production-ready.
