 - **Required**: `GHOST_URL`, `GHOST_CONTENT_API_KEY` or `GHOST_ADMIN_API_KEY` (at least one)
 - **Optional**: `GHOST_VERSION`, `MCP_GHOST_MODE`, logging settings
 
-### 4. Additional Features
-- **Question**: Are there any additional features beyond basic CRUD operations?

-  - Bulk operations
-  - Content analytics/statistics
-  - Webhook support for real-time updates
+### 4. Additional Features ✅ RESOLVED
+- **Decision**: Everything available in the Ghost REST API must be covered
+- **Implementation Strategy**: If too complex, implement stubs for future development
 
-### 5. Development Environment
-- **Question**: Should the development setup include sample Ghost content for testing?
-- **Impact**: Makes testing and development easier but increases setup complexity
