🎉 First Release: Production-Ready MCP Server Framework

We are excited to announce the first release of the MCP Server Framework! This release transforms the framework into a production-ready solution with comprehensive functionality, testing, and documentation.

✨ Key Features

🧪 Comprehensive Test Coverage

  • 42 Tests Total: Complete test coverage across all components
  • SSE Transport (14 tests): Health checks, message handling, session management, error handling
  • MCP Server (14 tests): Server creation, handler registration, tools functionality, capabilities
  • Client (14 tests): All client functionality with proper error handling

🔧 Complete MCP Protocol Implementation

  • ✅ Initialize/Initialized: Proper capability negotiation and notification handling
  • ✅ Tools Support: Complete tools/list and tools/call handlers
  • ✅ Echo Tool: Built-in example tool for testing and demonstration
  • ✅ Error Handling: JSON-RPC compliant error responses
  • ✅ Session Management: Proper SSE session validation and management

🐳 Docker Ready

  • SSE by Default: Docker container uses SSE transport out of the box
  • User-Friendly Configuration: Simple port format (8080 instead of :8080)
  • Production Ready: Optimized for deployment and scaling

📚 Comprehensive Documentation

  • API Documentation (docs/API.md): Complete endpoint reference with curl examples
  • Testing Guide (docs/TESTING.md): Detailed test coverage documentation
  • SSE Documentation (docs/SSE.md): SSE-specific transport guide
  • Updated README: Correct examples and usage instructions

🔧 Integration Testing

  • Bash Test Script: Comprehensive integration testing with cleanup
  • Python SSE Client: Proper SSE integration with request/response correlation
  • Curl Examples: Working examples for all endpoints and MCP methods

🚀 Quick Start

Docker (Recommended)

docker build -t mcp-server .
docker run -p 8080:8080 mcp-server

Binary

go build -o bin/mcp-server cmd/mcp-server/main.go
./bin/mcp-server -transport=sse -addr=8080

Health Check

curl http://localhost:8080/health
# {"status":"ok","transport":"sse","clients":0,"timestamp":1749244000}

📊 API Endpoints

Endpoint Method Purpose Status
/health GET Server health check ✅ Working
/sse GET SSE connection ✅ Working
/message POST Send MCP messages ✅ Working

🧪 Testing

# Run all tests
go test ./...

# Integration tests
./scripts/test-examples.sh

# Python SSE integration
python3 scripts/test_sse_integration.py 8080

🔄 MCP Protocol Support

  • Protocol Version: 2024-11-05
  • Transport: SSE (Server-Sent Events) and STDIO
  • Capabilities: Tools support with list and call operations
  • Error Handling: Full JSON-RPC error compliance

📈 What's New

  • Complete Tools Implementation: Full tools/list and tools/call support
  • Fixed Notification Handling: Proper distinction between requests and notifications
  • Enhanced Session Management: Robust SSE session validation
  • Production Docker Setup: SSE transport by default with user-friendly configuration
  • Comprehensive Testing: 42 tests covering all functionality and edge cases
  • Complete Documentation: API docs, testing guides, and usage examples
  • Integration Testing: Bash and Python integration test suites

🐛 Bug Fixes

  • Fixed SSE notification handling (was treating all messages as requests)
  • Enhanced port format handling (accepts 8080 instead of requiring :8080)
  • Improved error handling and JSON-RPC compliance
  • Fixed session management and validation

📝 Breaking Changes

None! This release maintains full backward compatibility while adding new functionality.
