Hey folks!
Quick post here to talk about a recent release for Forgetful, the open source AI Memory MCP.
I say recent, it's actually coming up to a month since I actually pushed the release, 15th Jan was when version 0.2.0 was pushed.
Since then I've been utilising Forgetful in some quite big projects in my day to day work and also, in the evenings when everyone in my household is asleep and I get to play, I've been building some cool little apps on the back of it.
One of the key features of 0.2.0 was the Server Side Event streaming and activity tracking. If you are running this as a service or a docker container, then it is available under /api/v1/activity/stream
With this feature enabled, you can now have other services subscribe to an events endpoint and then whenever events take place, such as for example when a new memory gets created, an entities list of aliases gets appended or a obsolete code artifact is deleted, services that are subscribed will be notified.
The obvious benefit is that if you are building tools, agents or applications around Forgetful, then previously you would have had to to poll for data changes. This is no longer the case now, Forgetful now has a heartbeat and anything that cares to listen can hear it.
As part of the release itself I also optimised the graph endpoint, which is used to bring back your full knowledge graph, and it now supports pagination and sorting.
All this should aid users who are looking to build visual applications around forgetful itself, which I know as coding agents get better, more and more of us will want to do.
All this came off the back of feedback from users of the tool and collated over discord, reddit and dev.to communities. Which is nice as part of the reason I enjoy open source is because of the community aspect, so please keep offering up ideas and contributions.
I went about implementing this, with Claude Code, since Opus 4.5 i code less now and mostly just have a back and forth with Claude Code and let it write the code. Most of forgetful itself was hand written, or at least a significant amount of the walking skeleton was with Sonnet 4.5 filling in the remaining verticals once I had authorisation, memories and user veriticals completed. Now however with new projects I reference my patterns from Forgetful so the agent itself can build the walking skeleton with me just through conversations.
From my own work I haad used event bus architecture before, so I decided that would be the obvious pattern here. So I asked Claude to implement that based on an exmaple it had seen in Forgetful from an old project I had encoded.
I then implemented a queue based handler to emmit events to SSE clients, from a seperate example of another solution I had used previously but had encoded the solution into Forgetful.
I could have just told the AI to look at the code, but pointing it at a directory, specifiying the exact piece of code and so on, was much harder than me just typing 'use the event bus pattern I used in x", I enjoy it when the work I have put in in the past, means I can can be super lazy now :-D.
Oh and to show off a bit of my own front end vibe coding (I am a backend engineer at heart) - check out my video of my own personal assistant AI that I am working on.
It's a pet project I've been working on for over 6 months (the memory for which was one of the main drivers behind developing Forgetful :)).
Enjoy!
