Hey, thanks for the kind words — and for the CLI/agent-memory idea. I haven’t fully leaned into “index what the agents did in the repo” yet; that’s a great direction. The MCP server gets most of the love so far, but the CLI is the same pipeline (sync → chunk → embed → search), so wiring it in so agents can search their own history is totally doable. I’ll keep that in mind.
This is used to build the search index on the website (below)
This tool is made for not only local, but embedded in a ci context
MemoryLane looks really cool — same problem, different surface. Local embeddings + SQLite + hybrid FTS/vector + MCP into Claude is basically the same stack; the screenshot-ingestion and Electron UX are a neat take for “everything I’ve seen on this machine.” I’ll definitely poke around the repo.
If you want to see how we’re using custom agents on top of that pipeline, a couple of blog posts go into it: Chat with your blog
I have mostly used the entire API surface so far. Check out the usage in this github action script: https://github.com/parallax-labs/context-harness/blob/main/s...

- https://parallax-labs.github.io/context-harness/blog/enginee... (persona grounded in your own writing, inline + Lua agents) this is in the same vein. Allowing agents to write into the vector store with an MCP tool is on the road map.
