Chats are buffered per user and batch-processed into profile fields and events, so apps can pull a user's key memories quickly instead of running a search. The server uses FastAPI, Postgres and Redis and runs in Docker; Memobase Cloud has a free tier. Python SDK `pip install memobase`, and the repo includes an MCP server (src/mcp). Apache-2.0.
