This commit implements Phase 1 of the MCP SDK migration plan:
installing the official Microsoft ModelContextProtocol SDK and
creating a Proof-of-Concept to validate SDK capabilities.
Changes:
- Installed ModelContextProtocol v0.4.0-preview.3 NuGet package
- Added SDK server configuration in Program.cs (parallel with custom MCP)
- Created SdkPocTools.cs with 3 attribute-based tools:
* Ping() - Simple test tool
* GetProjectInfo() - Tool with parameters
* GetServerTime() - Tool with dependency injection
- Created SdkPocResources.cs with 2 attribute-based resources:
* GetSdkStatus() - SDK integration status
* GetHealthCheck() - Health check resource
- Enabled auto-discovery of Tools and Resources from assembly
SDK Key Findings:
- ✅ Attribute-based registration works ([McpServerToolType], [McpServerTool])
- ✅ [Description] attribute for tool/parameter descriptions
- ✅ Dependency injection supported (ILogger<T> works)
- ✅ Parameter marshalling works (Guid, bool, defaults)
- ✅ Async Task<T> return types supported
- ⚠️ McpServerResource attribute ONLY works on methods, NOT properties
- ✅ Compilation successful with .NET 9
Next Steps (Phase 2):
- Test SDK PoC at runtime (verify Tools/Resources are discoverable)
- Analyze SDK API for Resource URI patterns
- Compare SDK vs. custom implementation performance
- Create detailed migration plan
