Browser for AI Agent

Let AI agents read and control browser tabs through MCP.

Features & Capabilities

Browser for AI Agent is a browser extension for AI agents. It connects to a local Native Messaging Host and exposes an MCP service, allowing MCP-compatible AI agents to read browser tab content, inspect tab information, and call page tools in the user’s browser environment.

Features:

  • Read active tab content, title, URL, page errors, and localStorage
  • Access cookies for browser automation tasks explicitly requested by the user
  • Execute scripts in tabs or in the extension background
  • Manage and call toolsets for repeatable web automation workflows
  • Support page-provided tools through WebMCP
  • Subscribe to community or custom toolsets
All capabilities are exposed through a local MCP service configured by the user. The extension does not sell user data or use it for advertising. Only connect trusted AI agents and subscribe to toolsets from trusted sources.

Is Browser for AI Agent Safe?

Risk impact
Risk impact measures the level of extra permissions an extension has access to. A low risk impact extension cannot do much harms, whereas a high risk impact extension can do a lot of damage like stealing your password, bypassing your security settings, and accessing your personal data. High risk impact extensions are not necessarily malicious. However, if they do turn malicious, they can be very harmful.

Browser for AI Agent requires a lot of sensitive permissions. Exercise caution before installing.

Risk likelihood
Risk likelihood measures the probability that a Firefox add-on may turn malicious. This is determined by the publisher and the Firefox add-on reputation on Firefox Add-ons Store, the amount of time the Firefox add-on has been around, and other signals about the Firefox add-on. Our algorithms are not perfect, and are subject to change as we discover new ways to detect malicious extensions. We recommend that you always exercise caution when installing a Firefox add-on.

Browser for AI Agent is recently added, and hasn't been around long enough for us to gather enough data to accurately assess its risk level.
