Description
Give local MCP clients permission-controlled access to Chrome tabs. Tenmomo.ai Browser Agent is the Chrome companion for a local, open-source MCP browser broker. It lets coding agents inspect and operate Chrome only through a broker running on your own computer. Each MCP session may control only tabs that it created. Tabs opened by you or by another session remain read-only. Commands are serialized per tab, and closing or expiring a session releases its ownership without closing your browser tabs. The extension includes two explicit safety boundaries: Chrome's password and autofill stores are always outside agent authority, and actions on configured finance-transaction domains are denied unless the owner approves that one request. The extension rereads the page URL immediately before execution. The extension and broker communicate only over 127.0.0.1. There is no cloud service, analytics, advertising, remote account, or telemetry. The companion broker must be installed separately from the public source repository: https://github.com/tenmomo/browser-agent — Release notes — 0.3.0 — Stateless HTTP MCP endpoint on port 32147. No sessions or initialization handshake required — agents send tool calls directly. Loopback connections skip auth for local use. Finance-domain and password-store safety checks apply. 0.2.1 — Extension icons, optional scripting permission for site grants, symlink-safe server resolution. 0.2.0 — Initial public release. Multi-session broker with tab ownership, per-tab command serialization, finance-domain approval prompts, password-store exclusion, and execution-time URL recheck.
