Get page content in Markdown format, optimized for large language models
AI agents call browser_get_markdown to retrieve information from Concurrent Browser MCP without modifying anything — typically the context-gathering step in research, monitoring, and reporting workflows, before the agent takes action elsewhere.
This tool retrieves and converts visible page content to Markdown format. It is a read-only operation that extracts data from a webpage without creating side effects, modifying state, executing code, or performing destructive actions. The retrieval of page content poses minimal security risk as it only exposes information already visible in the browser context.

{
"version": "1",
"default": "deny",
"tools": {
"browser_get_markdown": {}
}
