MCP.Pizza Chef: Puliczek

Two tools do all the work: one saves something you want kept, the other finds it again later by meaning rather than exact wording, so asking what you eat for breakfast can surface a note about porridge. It runs on Cloudflare and stays free at ordinary volumes, roughly a thousand saved notes. A ready-made public instance exists that you can point at in minutes, but nothing checks who you are, and the code has not changed since April 2025.

MCP Memory

MCP Memory is a MCP Server that gives MCP Clients (Cursor, Claude, Windsurf and more) the ability to remember information about users (preferences, behaviors) across conversations. It uses vector search technology to find relevant memories based on meaning, not just keywords. It's built with Cloudflare Workers, D1, Vectorize (RAG), Durable Objects, Workers AI and Agents.

mcp-memory FAQ

Who else can read my memories?
Anyone who has your address. There is no password, key, sign-in or token of any kind. The web address you paste into your app contains a plain user name, and anyone who has that address can read, edit and delete everything stored under it.
The readme mentions a rate limit as protection. Does that help?
No. The limit of a hundred requests a minute is declared in the deployment settings but is never actually applied anywhere in the running code, so the protection the readme leans on does not exist. Treat this as an open notebook and keep anything sensitive out of it.
Does it cost anything?
Not for normal personal use. The free Cloudflare allowances cover roughly a thousand saved notes and about twenty-eight thousand look-ups a month. Beyond that you pay Cloudflare's usual rates for the storage and search it uses.
Do I need a key or an account?
Not if you use the ready-made public instance, which is free and needs nothing but a web address pasted into your app. Running your own copy needs a free Cloudflare account and a one-click deploy, plus a search index created with the right settings.
Which apps does it work in?
Cursor, Claude and Windsurf are named, and any app that accepts a remote MCP address will work the same way. Setup is pasting one small block containing your address.
Can I use this to stop repeating myself to my assistant?
Yes, that is exactly the point. You tell it your preferences once, and later conversations can search that store instead of starting cold every time.
Can it delete or list memories from chat?
No. Only two tools exist, one to save and one to search. Viewing and deleting happen through the web page attached to your own instance, not through your assistant.
Is it still maintained?
The code has not been touched since April 2025, more than a year ago. It also ships without a licence file, which means no permission to reuse it has formally been granted, so check with your employer before putting work information into it.
