## Key Research Findings

### 1. Authentication Patterns
- **Content API**: Simple query parameter authentication (`?key=api_key`)
- **Admin API**: JWT token authentication with 5-minute expiration
- **Implementation**: Node.js with jsonwebtoken library

### 2. Content Formats
- **Primary**: Lexical (JSON-based structured content)
- **Secondary**: HTML (for compatibility and input)
- **Legacy**: Mobiledoc (backward compatibility only)

### 3. API Response Patterns
- **Consistent Structure**: `{ resource_type: [...], meta: { pagination: {...} } }`
- **Error Format**: `{ errors: [{ message, context, type, ... }] }`
- **Filtering**: NQL (Node Query Language) with comprehensive operators

### 4. Error Handling Strategy
- **5 Categories**: Network, Authentication, Ghost API, MCP Protocol, File Upload
- **Comprehensive Logging**: Structured JSON with request IDs
- **Retry Logic**: Exponential backoff for transient errors

### 5. MCP Tool Architecture
- **Total Tools**: 44+ tools covering complete Ghost REST API
- **Content API**: 13 read-only tools
- **Admin API**: 31+ read/write tools including advanced features

## Implementation Readiness

### Phase 1 Prerequisites ✅
- [x] Complete API authentication documentation
- [x] Error handling patterns defined
- [x] Project structure created
- [x] TypeScript configuration ready
- [x] All dependencies specified

### Remaining for Phase 1
- [ ] **API Keys Required**: Need to complete Ghost admin setup and generate API keys
- [ ] **Implementation**: Begin Phase 1 core infrastructure development

## Next Steps

### Immediate Action Required
1. **Complete Ghost Setup**:
   - Navigate to http://localhost:2368/ghost
   - Create admin account
   - Generate Content and Admin API keys

2. **Begin Phase 1**:
   - Implement configuration system
   - Build authentication infrastructure
   - Set up logging and error handling

### Phase 1 Scope
According to PLAN.md, Phase 1 will implement:
- Configuration system with precedence (env vars → .env → defaults)
- Content and Admin API authentication
- Comprehensive logging system
- Error handling infrastructure

## Project Status

### Current State
- **Ghost Instance**: ✅ Running and accessible
- **Research**: ✅ Complete and documented
- **Project Setup**: ✅ Ready for development
- **API Keys**: ⏳ Pending manual generation
- **Implementation**: ⏳ Ready to begin Phase 1

### Success Criteria Met
- [x] Local Ghost instance running and accessible
- [x] Project structure created with all placeholder files
- [x] All dependencies installed and TypeScript compiling
- [x] Research documentation completed for authentication flows
- [x] Clear understanding of Ghost API error handling
- [ ] Both Content and Admin API keys obtained and tested (pending)

## Architecture Decisions Made

### 1. Technology Stack
- **Runtime**: Node.js v18+ with TypeScript
- **MCP SDK**: @modelcontextprotocol/sdk
- **HTTP Client**: axios (with retry and connection pooling)
- **Authentication**: jsonwebtoken for Admin API
- **Validation**: zod for runtime type checking
- **Logging**: winston for structured logging

### 2. Project Organization
- **Modular Tools**: Separate files for each resource type
- **API Separation**: Clear distinction between Content and Admin tools
- **Type Safety**: Comprehensive TypeScript types for all APIs
- **Error Handling**: Centralized error management with categories

### 3. Implementation Strategy
- **Phase-based Development**: Clear separation of concerns
- **Documentation-First**: All patterns documented before implementation
- **Testing-Ready**: Jest configuration and testing strategy planned
- **Production-Ready**: Comprehensive error handling and logging

## Documentation Quality
All contract documentation includes:
- ✅ Complete API specifications
- ✅ Implementation examples
- ✅ Error handling patterns
- ✅ Testing strategies
- ✅ Best practices and security considerations

## Phase 0 Conclusion
Phase 0 has successfully established a solid foundation for Ghost MCP development. The comprehensive research and documentation provide clear guidance for all subsequent phases. The project is now ready to proceed to Phase 1 implementation once API keys are generated.

**Estimated Time**: Phase 0 completed within planned 1-2 day timeframe.
**Quality**: High - comprehensive documentation and well-structured project setup.
**Readiness**: Ready for Phase 1 implementation.
