+# Blog MCP
+
+AI-powered blog writing assistant with tone of voice and visual style guides.
+
+## Overview
+
+The Blog MCP helps AI agents write blog articles with consistent voice and style. It provides:
+
+- **Prompts** for setting up blogs, creating style guides, and writing articles
+- **Tools** for generating cover images and validating article structure
+- **Resources** with templates for tone of voice and visual style guides
+
+## Key Concept
+
+Articles are stored as **markdown files with YAML frontmatter** in the git repository. The MCP guides the workflow - the agent reads/writes files directly. This enables:
+
+- Git-based version control for all content
+- Easy integration with static site generators
+- Future compatibility with deco.cx git-based editor
+
+## File Structure
+
+```
+project/

+## Article Format

+date: 2025-01-27
