Fetch any URL as clean markdown (Firecrawl). Costs $0.015 per call via x402.
AI agents call scrape_url to retrieve information from X402 Agents without modifying anything — typically the context-gathering step in research, monitoring, and reporting workflows, before the agent takes action elsewhere.
This tool retrieves and transforms web content into markdown. It performs no data modification, deletion, code execution, or financial transaction. The ability to scrape arbitrary URLs presents minimal risk in isolation — the blast radius is limited to reading publicly accessible web content. Cost tracking ($0.015 per call) is a metering concern, not a security risk that would elevate severity.
From the tool's definition Tool description explicitly states 'Fetch any URL as clean markdown' — a retrieval operation with no side effects. Firecrawl is a web scraping service that returns content in markdown format.
Attacks that exploit this kind of access
Fetch any URL as clean markdown (Firecrawl). Costs $0.015 per call via x402. It is categorised as a Read tool in the X402 Agents MCP Server, which means it retrieves data without modifying state.
Register the X402 Agents MCP server in PolicyLayer and add a rule for scrape_url: 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 X402 Agents. Nothing to install.
scrape_url 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 scrape_url 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 scrape_url. 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.
scrape_url is provided by the X402 Agents MCP server (enrichgateagent-png/x402-agents). PolicyLayer sits as a proxy in front of this server to enforce policies before tool calls reach the server.
scrape_url is one line of X402 Agents's registry record.
The record carries the whole server: verified identity, auth posture, risk grade, every tool classified, recommended policy — re-checked continuously.
