GBrain Tools launches as a password manager for AI agents

GBrain, a product from Garry Tan's team, has launched under the name GBrain Tools on Product Hunt. The maker describes it as a password manager for AI, where accounts are connected once and then used from ChatGPT, Claude, Claude Code, Cursor or a terminal.

According to the maker, no AI holds a password itself, and each one only gets the access the user gives it. Every action it takes is recorded in one shared log. The listing gives the price as $19 a month and separately describes GBrain's memory as a folder of markdown files that users can read, edit and export.

The maker says the team built the tool because it kept reconnecting its apps whenever a new AI model or open-source harness came out. Connections can be reached over MCP or with a command line tool called gbrainio. The page also offers $100 off the first month of a team workspace.

Developers building agents can reach third-party accounts over MCP or from a terminal without putting credentials into each tool's config file. A single log of agent actions and per-tool access grants could make it easier to audit what an agent did. The security and pricing claims come from the maker's listing and have not been checked elsewhere.
