读取网页的主要内容。当需要阅读特定网页的文本内容时使用此工具（不包括 GitHub，GitHub 相关内容请使用专门的 GitHub 工具）。此工具会自动提取主要内容，忽略广告、导航栏等干扰元素。支持普通 HTML 页面和需要 JS 渲染的页面。
AI agents call read_webpage to retrieve information from MCP Toolkit without modifying anything — typically the context-gathering step in research, monitoring, and reporting workflows, before the agent takes action elsewhere.
The tool's core function is to fetch and extract text content from web pages. It has no side effects, does not modify data, does not execute arbitrary operations, and does not involve financial transactions. It is a straightforward read operation similar to a GET request.
From the tool's definition Tool description states '读取网页的主要内容' (reads main content of webpages) and 'automatically extracts main content' with no mention of modifying, deleting, executing code, or financial operations. This is purely a retrieval operation.

Register the MCP Toolkit MCP server in PolicyLayer and add a rule for read_webpage: 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 Toolkit. Nothing to install.
read_webpage 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 read_webpage 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 read_webpage. 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.
read_webpage is provided by the MCP Toolkit MCP server (zxfgds/mcp-toolkit). PolicyLayer sits as a proxy in front of this server to enforce policies before tool calls reach the server.
