Own your context.
openmemfs is a memory made of text files, kept in your own Postgres. You read and edit it in a Notion-style editor; your agents read and write the same files through MCP and a REST API. Change harness whenever you like: your context stays.
git clone https://github.com/gverdugo-dev/openmemfs.git
cd openmemfs && docker compose up
claude mcp add --transport http openmemfs http://localhost:8080/mcpYours
Your server, your database, your rules. Plain files you can export, read and move.
Any agent
Every harness that speaks MCP gets the same tools: list, read, write, tag, search, commit.
Personal
One person and their agents. No accounts out of the box: add only what you need.
Extend it
Small on purpose, extended by modules. Ask your agent for a tab, a tool or a page, and share it.
The guides
Short, and in order: from why it exists to running it in the cloud.
