FAQ from Browser Control MCP

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.

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).

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.
