Search captured network requests by keyword (supports regex). Useful for finding API endpoints that contain specific data.
AI agents call browser_search_requests to retrieve information from Playwright MCP Server without modifying anything — typically the context-gathering step in research, monitoring, and reporting workflows, before the agent takes action elsewhere.
This tool retrieves and filters previously captured network request data. While it operates within a browser automation context (which could enable malicious scraping), the tool itself performs only read operations on cached request logs.
From the tool's definition Tool description states 'Search captured network requests by keyword' - a read-only query operation. The word 'search' and 'finding' indicate data retrieval without modification. No mutations, deletions, or side effects are described.
Attacks that exploit this kind of access
Search captured network requests by keyword (supports regex). Useful for finding API endpoints that contain specific data. It is categorised as a Read tool in the Playwright MCP Server MCP Server, which means it retrieves data without modifying state.
Register the Playwright MCP Server MCP server in PolicyLayer and add a rule for browser_search_requests: 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 Playwright MCP Server. Nothing to install.
browser_search_requests 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 browser_search_requests 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 browser_search_requests. 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.
browser_search_requests is provided by the Playwright MCP Server MCP server (leviathangk/playwrightmcpforcrawler). PolicyLayer sits as a proxy in front of this server to enforce policies before tool calls reach the server.
