Notes

• Notes are stored locally in the notes/ folder

• The notes/ folder is ignored in git

• The server runs over stdio

Why I Built This

I built this project to get hands-on experience with MCP by creating a practical local productivity tool. It helped me understand how MCP tools, resources, and prompts work together in a real Claude Desktop integration.

Future Improvements

• Support Apple Pages

• Support Google Docs

• Search notes by keyword

• Read notes by exact filename

• Add tags or metadata to notes

• Add better summarization workflows
