Memory Kit · MCP Edition · $69 once

One brain. Every app. Your file.

A Model Context Protocol server with six memory tools, speaking stdio and streamable HTTP, over one SQLite file that lives where you put it. Everything below is the whole story — what it does, which apps it plugs into, and the honest limits — sentence for sentence.

Memory Kit — MCP Edition

One brain. Every app. Your file.
Ready — arriving with the app

For the people working out of a terminal. Tell Claude on Monday that you take your coffee black; ask Grok on Wednesday how you take your coffee. Same file. Two companies. One brain. It is a Model Context Protocol server with six tools — remember, recall, save a conversation summary, forget, stats, and a review pass for pruning — speaking both stdio and streamable HTTP, over one SQLite file that lives where you put it. Zero dependencies. Unzip, init, connect.

01 · Claude Desktop

Over stdio

The privacy-maximum lane. Run it locally over stdio and the server is a process on your machine with your data on your own disk and nothing on a network. Run the HTTP door for web and phone apps and it sits behind a bearer token, on your disk or on a box you rent — your choice, and the README says exactly what each choice means.

02 · Claude web & mobile

As a custom connector

The phone answer. Run the HTTP transport behind a tunnel or your own cloud box and add it as a custom connector.

03 · Claude Code

In the terminal

The same six tools inside the coding agent you already have open, reading and writing the same local database file.

04 · Grok

Bring your own MCP

Point it at the HTTP endpoint. When an app supplies its name, the kit records it, so stats can show that one client wrote sixty entries and another wrote twelve. A name is a label the caller reports, not an authenticated identity, and a merged memory keeps one surviving label.

Which one do you want? If you already live in a terminal, you want the MCP edition. If you want a thing you install that just opens and talks to you, you want the app. They are sold as two products because they are two different days of your life — one for terminal people, one for everyone else.
About ChatGPT: its connector surfaces mostly expect OAuth, and this kit does not ship an OAuth server in v1 — so if the only option you are offered is "connect with OAuth," it cannot attach as it stands. An OAuth layer is in development across our MCP products. It is not in v1, and nothing here depends on it landing.

Also true: ranking is keyword, recency and importance — not embeddings — so a question sharing no words with a memory can miss it. And nothing fires automatically at the start or end of a chat; the kit ships a taught-habit paragraph per app, and "save this conversation to memory" works in every client that speaks MCP — a habit you teach, not a hook that fires on its own.
Both pieces, one idea: each keeps its memory in a plain local SQLite file on your own machine — a file you can read, export, back up and carry to another computer. Nobody rents you your own memory.
