What it is
A service that stores notes and finds them again by meaning rather than by exact words. It speaks MCP, a standard way for assistants to connect to outside tools, and it also offers a plain web interface. It makes the number lists for the search itself, on your machine, so no search text is sent anywhere.
What it is good for. Anyone using a coding assistant on a long-running project who is tired of explaining the same decisions. It is also the narrower, smaller alternative to the big memory libraries: a thing you install and point an assistant at rather than a library you write code against.
- This project moved the opposite way from the usual. Its copy on Codeberg carries a notice that development moved to GitHub on 5 September 2026 and that the Codeberg copy is frozen. This report has recorded five projects leaving GitHub for Codeberg since September. This is the first it has found going the other way.
- Apache-2.0 with the holder properly named —
Copyright 2024 Heinrich Krupp— and aNOTICEfile beside it. One of only six in this edition that names a holder at all. - 21 open issues and 7 open pull requests against 752 closed pull requests. Version 11.15.0 landed on 3 October 2026, confirmed through Python's package index.
- The project's own instructions clone the wrong place. Its advanced-install and developer steps still say
git clone https://codeberg.org/doobidoo/mcp-memory-service.git, which is the copy Codeberg itself declares frozen with no further pushes. Clone from GitHub instead. - The release pace is extreme and includes security fixes. It went from version 10.66 to 11.15 in about four months, and its own change log records a fix for an authentication bypass rated 9.8 out of 10, where document routes were reachable without signing in. Falling behind on upgrades here is a real risk, and the project is less than a year old.
- No memory, disk or processor figure is published anywhere, even though it runs a search model and a database on your machine. The README states Python 3.8 or newer while the published package requires 3.10 or newer — the package is right.
mem0ai/mem0The best known of these, a library you write code against rather than a service you install, and it calls a paid model to decide what to remember; covered as entry #12 of Edition 28.

Keeps the memory as ordinary Markdown files you can read and edit yourself; AGPL-3.0 and a paid cloud tier alongside the free local install.

Worth naming so it is not mistaken for the product: the repository states it is not Zep's own service, only examples and integrations for the hosted one, so there is nothing here to self-host.
