MCP Notes Server
A small Model Context Protocol (MCP) server that gives an AI a personal notes / todo store. Built for learning.
What is MCP?
MCP is an open standard that lets an AI model call functions in your code.
You expose tools (functions with a name, description, and typed inputs);
the AI reads the descriptions and decides when to call them. Communication
here happens over stdio — the AI client launches notes-server.js and exchanges
JSON messages over stdin/stdout.
Tools in this server
| Tool | What it does |
|---|---|
add_note |
Add a new note/todo |
list_notes |
List notes (filter: all / open / done) |
search_notes |
Search notes by keyword |
complete_note |
Mark a note done by id |
delete_note |
Delete a note by id |
Notes are saved to notes.json next to the server, so they survive restarts.
Run it
npm install
npm start # prints "notes-server running on stdio" then waits
It looks like it "hangs" — that's correct. It's waiting for an AI client to talk to it over stdin. Press Ctrl+C to stop.
Connect it to Claude Code (CLI)
claude mcp add notes -- node /home/tw/Documents/mcp/notes-server.js
Then in a Claude Code session, try: "Add a note to buy milk", then "list my open notes".
