An extension for Chrome, Opera, Edge, and Firefox that integrates with KeePass, MacPass, and KeePassXC to find and fill credentials, generate secure passwords and passkeys, and save new logins directly to your database—no manual copying required.
This extension can be used with coding agents such as OpenCode. Read FAQs page for more info. Also check the mcp.json (LLM tool definition) file which defines available tools for an agent, using JSON-RPC 2.0 as the envelope and JSON Schema for input/output.
