Extracts text content from an element. Accepts CSS/XPath selector or ref=N from snapshot.
AI agents call extract_text to retrieve information from Brave Browser MCP Server without modifying anything — typically the context-gathering step in research, monitoring, and reporting workflows, before the agent takes action elsewhere.
This tool queries and retrieves text content from DOM elements without creating, modifying, deleting, or executing any operations. It is a passive data retrieval mechanism, consistent with Read category tools like 'get' or 'fetch'. The low severity reflects minimal risk even if an agent extracts sensitive text, as the tool itself performs no irreversible actions.
From the tool's definition Tool name 'extract_text' and description 'Extracts text content from an element' indicate retrieval of data with no side effects or modifications to the browser state or content.
Attacks that exploit this kind of access

Register the Brave Browser MCP Server MCP server in PolicyLayer and add a rule for extract_text: allow, deny, rate-limit, or require approval. Point your MCP client at the PolicyLayer proxy URL and the rule is enforced on every call, before it reaches Brave Browser MCP Server. Nothing to install.
extract_text is a Read tool with low risk. Read-only tools are generally safe to allow by default.
Yes. Add a rate_limit block to the extract_text rule in your PolicyLayer policy. For example, setting max: 10 and window: 60 limits the tool to 10 calls per minute. Rate limits are tracked per agent session and reset automatically.
Set action: deny in the PolicyLayer policy for extract_text. The AI agent will receive a policy violation error and cannot call the tool. You can also include a reason field to explain why the tool is blocked.
extract_text is provided by the Brave Browser MCP Server MCP server (slaveofgod1/brave-browser-mcp). PolicyLayer sits as a proxy in front of this server to enforce policies before tool calls reach the server.
