AI agents call firecrawl_extract to retrieve information from Firecrawl Web Scraping Server without modifying any data. This is common in research, monitoring, and reporting workflows where the agent needs context before taking action. Because read operations don't change state, they are generally safe to allow without restrictions -- but you may still want rate limits to control API costs.
Even though firecrawl_extract only reads data, uncontrolled read access can leak sensitive information or rack up API costs. An agent caught in a retry loop could make thousands of calls per minute. A rate limit gives you a safety net without blocking legitimate use.
Read-only tools are safe to allow by default. No rate limit needed unless you want to control costs.

Extract structured information from web pages using LLM capabilities. Supports both cloud AI and self-hosted LLM extraction. Best for: Extracting specific structured data like prices, names, details. Not recommended for: When you need the full content of a page (use scrape); when you're not looking for specific structured data. Arguments: - urls: Array of URLs to extract information from - prompt: Custom prompt for the LLM extraction - systemPrompt: System prompt to guide the LLM - schema: JSON schema for structured data extraction - allowExternalLinks: Allow extraction from external links - enableWebSearch: Enable web search for additional context - includeSubdomains: Include subdomains in extraction Prompt Example: "Extract the product name, price, and description from these product pages." Usage Example: json { "name": "firecrawl_extract", "arguments": { "urls": ["https://example.com/page1", "https://example.com/page2"], "prompt": "Extract product information including name, price, and description", "systemPrompt": "You are a helpful assistant that extracts product information", "schema": { "type": "object", "properties": { "name": { "type": "string" }, "price": { "type": "number" }, "description": { "type": "string" } }, "required": ["name", "price"] }, "allowExternalLinks": false, "enableWebSearch": false, "includeSubdomains": false } } Returns: Extracted structured data as defined by your schema.. It is categorised as a Read tool in the Firecrawl Web Scraping Server MCP Server, which means it retrieves data without modifying state.
Register the Firecrawl Web Scraping Server 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 Firecrawl Web Scraping Server. 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 Firecrawl Web Scraping Server MCP server (NYO2008/firecrawl-mcp-server). PolicyLayer sits as a proxy in front of this server to enforce policies before tool calls reach the server.
