概要

What is Browser Control MCP?

Browser Control MCP is an MCP server paired with a Firefox browser extension that gives AI assistants access to tab management, browsing history, and webpage text content. It provides a secure alternative to web automation MCP servers for controlling the user’s personal browser.

How to use Browser Control MCP?

Install the Firefox add-on from addons.mozilla.org or as a temporary add-on, then configure the MCP server in your mcpServers config (e.g., claude_desktop_config.json) with the EXTENSION_SECRET and optional EXTENSION_PORT. Alternatively, build from source or use the provided Docker image.

よくある質問

1

How does Browser Control MCP differ from web automation MCP servers?

It is designed to be more secure: it does not support page modification, page interactions, or arbitrary scripting. Reading webpage content requires explicit user consent per domain, and the connection is local-only with a shared secret. No remote data collection or tracking occurs.

2

What are the runtime requirements?

You need Firefox (or Firefox Developer Edition) and the Browser Control MCP browser extension. The MCP server runs locally and communicates with the extension via a configurable port (default 8089).

3

How is security handled?

User consent is enforced for reading webpage content and highlighting text. The extension provides an audit log of tool calls and tool enable/disable configuration. The MCP server uses a local-only connection with a shared secret. No third-party runtime dependencies are included in the extension.

4

Is Browser Control MCP stable?

It is marked as experimental. Use at your own risk, and exercise caution when authorizing or monitoring tool calls.

5

Which browsers are supported?

Only Firefox is supported (including Firefox Developer Edition). The extension is available via addons.mozilla.org or as a temporary add-on.
