Plow Latch
Safely handle logins and credential entry for AI agents without putting passwords in model context
About Plow Latch
Plow Latch helps MCP-compatible AI agents complete browser actions that require login. Users can review the accounts, sites, files, and commands involved, then choose one-time or ongoing permission; Latch fills approved credentials directly in the browser, keeping them out of the agent's context and logs. The vault is encrypted on Mac, its key is protected by macOS Keychain, and no cloud copy is retained.
