OpenClaw
OpenClaw, running on a brain you own.
The open-source harness this product runs inside, with your memory attached.
OpenClaw is the open-source agent harness gbrain itself runs inside, so this is the pairing the whole thing was built around. Run it yourself and it starts with no memory of anything before the session you are in.
Point it at a gbrain workspace and it gets two things. Memory, as a place to write what it learns and read it back next week. And tools, over one MCP server rather than a folder of configs, each with its own key on disk.
You choose which tools it sees. The token in its config can be revoked without touching the harness.
