[STATELESS] Extract content as markdown with filtering options. Supports: raw (full content), fit (optimized, default), bm25 (keyword search), llm (AI-powered extraction). Use bm25/llm with query for specific content. Creates new browser each time. For persistence use create_session + crawl.
AI agents call get_markdown to retrieve information from MCP Server for Crawl4AI without modifying anything — typically the context-gathering step in research, monitoring, and reporting workflows, before the agent takes action elsewhere.
The tool retrieves and extracts web content in markdown format with various filtering strategies (raw, fit, bm25, llm). It performs content extraction and querying with no side effects—it does not modify, delete, or execute code on the target system. The explicit mention of 'Extract content' and 'Creates new browser each time' (implying a stateless read-only operation) confirms this is a Read category tool.
From the tool's definition Extract content as markdown with filtering options...Creates new browser each time.
Documented attack patterns abuse exactly the kind of access get_markdown gives an agent:
PolicyLayer is an MCP gateway — it sits between your AI agents and MCP Server for Crawl4AI, and nothing reaches the server without passing your rules. This is the rule we recommend for get_markdown:
{
"version": "1",
"default": "deny",
"tools": {
"get_markdown": {}
}
}get_markdown is read-only, so it stays allowed — but everything else on the server is denied unless you say otherwise.

Set action: deny in the PolicyLayer policy for get_markdown. 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.
get_markdown is provided by the MCP Server for Crawl4AI MCP server (omgwtfwow/mcp-crawl4ai-ts). PolicyLayer sits as a proxy in front of this server to enforce policies before tool calls reach the server.
Start from MCP Server for Crawl4AI, add the rest of your stack, and see everything your agents can call. Then put policy on all of it.
