61e0f1249c fix(backend): Fix MCP module compilation errors by using correct exception classes
Replaced non-existent ColaFlow.Shared.Kernel.Exceptions namespace references
with ColaFlow.Modules.Mcp.Domain.Exceptions in 5 files:

Changes:
- McpToolRegistry.cs: Use McpInvalidParamsException and McpNotFoundException
- AddCommentTool.cs: Use McpInvalidParamsException and McpNotFoundException
- CreateIssueTool.cs: Use McpInvalidParamsException, McpNotFoundException, and ProjectId.From()
- UpdateStatusTool.cs: Use McpNotFoundException
- ToolParameterParser.cs: Use McpInvalidParamsException for all validation errors

All BadRequestException -> McpInvalidParamsException
All NotFoundException -> McpNotFoundException

Also fixed CreateIssueTool to convert Guid to ProjectId value object.

3ab505e0f6 feat(backend): Implement Story 5.6 - Resource Registration & Discovery
Implemented pluggable resource registration and auto-discovery mechanism for MCP Resources.

Changes:
- Enhanced McpResourceDescriptor with metadata (Category, Version, Parameters, Examples, Tags, IsEnabled)
- Created ResourceDiscoveryService for Assembly scanning and auto-discovery
- Updated McpResourceRegistry with category support and grouping methods
- Enhanced ResourcesListMethodHandler to return categorized resources with full metadata
- Created ResourceHealthCheckHandler for resource availability verification
- Updated all existing Resources (Projects, Issues, Sprints, Users) with Categories and Versions
- Updated McpServiceExtensions to use auto-discovery at startup
- Added comprehensive unit tests for discovery and health check

Features:
 New Resources automatically discovered via Assembly scanning
 Resources organized by category (Projects, Issues, Sprints, Users)
 Rich metadata for documentation (parameters, examples, tags)
 Health check endpoint (resources/health) for monitoring
 Thread-safe registry operations

bfd8642d3c feat(backend): Implement Story 5.5 - Core MCP Resources Implementation
Implemented 6 core MCP Resources for read-only AI agent access to ColaFlow data:
- projects.list - List all projects in current tenant
- projects.get/{id} - Get project details with full hierarchy
- issues.search - Search issues (Epics, Stories, Tasks) with filters
- issues.get/{id} - Get issue details (Epic/Story/Task)
- sprints.current - Get currently active Sprint(s)
- users.list - List team members in current tenant

Changes:
- Created IMcpResource interface and related DTOs (McpResourceRequest, McpResourceContent, McpResourceDescriptor)
- Implemented IMcpResourceRegistry and McpResourceRegistry for resource discovery and routing
- Created ResourcesReadMethodHandler for handling resources/read MCP method
- Updated ResourcesListMethodHandler to return actual resource catalog
- Implemented 6 concrete resource classes with multi-tenant isolation
- Registered all resources and handlers in McpServiceExtensions
- Added module references (ProjectManagement, Identity, IssueManagement domains)
- Updated package versions to 9.0.1 for consistency
- Created comprehensive unit tests (188 tests passing)
- Tests cover resource registry, URI matching, resource content generation

Technical Details:
- Multi-tenant isolation using TenantContext.GetCurrentTenantId()
- Resource URI routing supports templates (e.g., {id} parameters)
- Uses read-only repository queries (AsNoTracking) for performance
- JSON serialization with System.Text.Json
- Proper error handling with McpNotFoundException, McpInvalidParamsException
- Supports query parameters for filtering and pagination
- Auto-registration of resources at startup

Test Coverage:
- Resource registry tests (URI matching, registration, descriptors)
- Resource content generation tests
- Multi-tenant isolation verification
- All 188 tests passing

c00c909489 feat(backend): Implement Story 5.4 - MCP Error Handling & Logging
Implement comprehensive error handling and structured logging for MCP module.

**Exception Hierarchy**:
- Created McpException base class with JSON-RPC error mapping
- Implemented 8 specific exception types (Parse, InvalidRequest, MethodNotFound, etc.)
- Each exception maps to correct HTTP status code (401, 403, 404, 422, 400, 500)

**Middleware**:
- McpCorrelationIdMiddleware: Generates/extracts correlation ID for request tracking
- McpExceptionHandlerMiddleware: Global exception handler with JSON-RPC error responses
- McpLoggingMiddleware: Request/response logging with sensitive data sanitization

**Serilog Integration**:
- Configured structured logging with Console and File sinks
- Log rotation (daily, 30-day retention)
- Correlation ID enrichment in all log entries

**Features**:
- Correlation ID propagation across request chain
- Structured logging with TenantId, UserId, ApiKeyId
- Sensitive data sanitization (API keys, passwords)
- Performance metrics (request duration, slow request warnings)
- JSON-RPC 2.0 compliant error responses

**Testing**:
- 174 tests passing (all MCP module tests)
- Unit tests for all exception classes
- Unit tests for all middleware components
- 100% coverage of error mapping and HTTP status codes

**Files Added**:
- 9 exception classes in Domain/Exceptions/
- 3 middleware classes in Infrastructure/Middleware/
- 4 test files with comprehensive coverage

**Files Modified**:
- Program.cs: Serilog configuration
- McpServiceExtensions.cs: Middleware pipeline registration
- JsonRpcError.cs: Added parameterless constructor for deserialization
- MCP Infrastructure .csproj: Added Serilog package reference

**Verification**:
 All 174 MCP module tests passing
 Build successful with no errors
 Exception-to-HTTP-status mapping verified
 Correlation ID propagation tested
 Sensitive data sanitization verified

48a8431e4f feat(backend): Implement MCP Protocol Handler (Story 5.1)
Implemented JSON-RPC 2.0 protocol handler for MCP communication, enabling AI agents to communicate with ColaFlow using the Model Context Protocol.

**Implementation:**
- JSON-RPC 2.0 data models (Request, Response, Error, ErrorCode)
- MCP protocol models (Initialize, Capabilities, ClientInfo, ServerInfo)
- McpProtocolHandler with method routing and error handling
- Method handlers: initialize, resources/list, tools/list, tools/call
- ASP.NET Core middleware for /mcp endpoint
- Service registration and dependency injection setup

**Testing:**
- 28 unit tests covering protocol parsing, validation, and error handling
- Integration tests for initialize handshake and error responses
- All tests passing with >80% coverage

**Changes:**
- Created ColaFlow.Modules.Mcp.Contracts project
- Created ColaFlow.Modules.Mcp.Domain project
- Created ColaFlow.Modules.Mcp.Application project
- Created ColaFlow.Modules.Mcp.Infrastructure project
- Created ColaFlow.Modules.Mcp.Tests project
- Registered MCP module in ColaFlow.API Program.cs
- Added /mcp endpoint via middleware

**Acceptance Criteria Met:**
 JSON-RPC 2.0 messages correctly parsed
 Request validation (jsonrpc: "2.0", method, params, id)
 Error responses conform to JSON-RPC 2.0 spec
 Invalid requests return proper error codes (-32700, -32600, -32601, -32602)
 MCP initialize method implemented
 Server capabilities returned (resources, tools, prompts)
 Protocol version negotiation works (1.0)
 Request routing to method handlers
 Unit test coverage > 80%
 All tests passing
