Fetch a website and return its content as raw HTML, markdown, or plain text
AI agents call fetchWebsite to retrieve information from Advanced Web Fetching MCP Server without modifying anything — typically the context-gathering step in research, monitoring, and reporting workflows, before the agent takes action elsewhere.
The fetchWebsite tool retrieves and transforms existing web content into different formats but does not create, modify, delete, or execute any operations. It is a straightforward data retrieval function with no side effects on the target system or data. The low severity reflects minimal risk unless the tool is used to access sensitive content, but the tool itself performs no risky operations.
From the tool's definition Tool description states 'Fetch a website and return its content as raw HTML, markdown, or plain text' - purely retrieves data with no modification, deletion, or execution capabilities.
Attacks that exploit this kind of access
Fetch a website and return its content as raw HTML, markdown, or plain text. It is categorised as a Read tool in the Advanced Web Fetching MCP Server MCP Server, which means it retrieves data without modifying state.
Register the Advanced Web Fetching MCP Server MCP server in PolicyLayer and add a rule for fetchWebsite: 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 Advanced Web Fetching MCP Server. Nothing to install.
fetchWebsite 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 fetchWebsite 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 fetchWebsite. 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.
fetchWebsite is provided by the Advanced Web Fetching MCP Server MCP server (llmbaseai/mcp-servers). PolicyLayer sits as a proxy in front of this server to enforce policies before tool calls reach the server.
