Convert a webpage URL to clean markdown. Returns markdown content with a quality score (0-100) indicating how well the content was extracted.
AI agents call convert_url to retrieve information from UnWeb MCP Server without modifying anything — typically the context-gathering step in research, monitoring, and reporting workflows, before the agent takes action elsewhere.
The tool fetches a remote URL and converts its content to markdown, returning the result. This is a read-only retrieval operation with no side effects on any external system. The only potential concern is SSRF (fetching internal URLs), which raises severity slightly above trivial, but the operation remains firmly in the Read category.

Register the UnWeb MCP Server MCP server in PolicyLayer and add a rule for convert_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 UnWeb MCP Server. Nothing to install.
convert_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 convert_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 convert_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.
