AI agents call url_to_pdf to retrieve information from Prince Cloud 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 url_to_pdf 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.

Fetch a URL and convert it to PDF using Prince. Args: url: URL of a document to fetch and convert style: Additional CSS to apply (inline stylesheet content) page_size: Page size (e.g., A4, letter) page_margin: Page margins (e.g., 20mm) javascript: Enable JavaScript execution pdf_profile: PDF profile (e.g., PDF/A-3b, PDF/UA-1) output_filename: Output filename for the PDF (default: "output.pdf"). It is categorised as a Read tool in the Prince Cloud MCP Server, which means it retrieves data without modifying state.
Register the Prince Cloud MCP server in PolicyLayer and add a rule for url_to_pdf: 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 Prince Cloud. Nothing to install.
url_to_pdf 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 url_to_pdf 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 url_to_pdf. 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.
url_to_pdf is provided by the Prince Cloud MCP server (https://prince.cloud/mcp). PolicyLayer sits as a proxy in front of this server to enforce policies before tool calls reach the server.
