Extract structured information from web pages using LLM.
AI agents call firecrawl_extract to retrieve information from Mcp Registry Registry without modifying anything — typically the context-gathering step in research, monitoring, and reporting workflows, before the agent takes action elsewhere.
Extraction of structured information from publicly accessible web pages is fundamentally a Read operation: it retrieves data without modifying or deleting anything. Severity is medium rather than low because web scraping can have side effects (rate-limiting, IP bans, or scraping restricted content) and the tool depends on LLM processing, which introduces indirect risks if misused at scale.
From the tool's definition Tool description states it 'Extract[s] structured information from web pages' — a retrieval operation. The 'firecrawl_' prefix groups it with sibling tools like firecrawl_scrape and firecrawl_search, which are data-gathering utilities.
Attacks that exploit this kind of access
Extract structured information from web pages using LLM. It is categorised as a Read tool in the Mcp Registry Registry MCP Server, which means it retrieves data without modifying state.
Register the Mcp Registry Registry MCP server in PolicyLayer and add a rule for firecrawl_extract: 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 Mcp Registry Registry. Nothing to install.
firecrawl_extract 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 firecrawl_extract 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 firecrawl_extract. 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.
firecrawl_extract is provided by the Mcp Registry Registry MCP server (@mastra/mcp-registry-registry). PolicyLayer sits as a proxy in front of this server to enforce policies before tool calls reach the server.
