render_hwp_page

Render a single page of an HWP/HWPX document as SVG. If output_path is omitted, the raw SVG string is returned inline (useful for direct LLM consumption). Args: file_path, page (0-based, default 0), output_path (optional).

How to control render_hwp_page ↓

AI agents call render_hwp_page to retrieve information from Hwp without modifying anything — typically the context-gathering step in research, monitoring, and reporting workflows, before the agent takes action elsewhere.

Low Risk

This tool reads a page from a document and converts it to SVG for viewing. It only retrieves/renders existing content with no side effects on the document or external systems.

From the tool's definition Render a single page of an HWP/HWPX document as SVG... the raw SVG string is returned inline

Documented attack patterns abuse exactly the kind of access render_hwp_page gives an agent:

PolicyLayer is an MCP gateway — it sits between your AI agents and Hwp, and nothing reaches the server without passing your rules. This is the rule we recommend for render_hwp_page:

policy.json
{
  "version": "1",
  "default": "deny",
  "tools": {
    "render_hwp_page": {}
  }
}

render_hwp_page is read-only, so it stays allowed — but everything else on the server is denied unless you say otherwise.

  1. Create a free account and register Hwp — nothing to install.
  2. Add this policy — paste it, or build it visually.
  3. Point your MCP client (Claude, Cursor, anything) at your gateway URL.

What does the render_hwp_page tool do? +

Render a single page of an HWP/HWPX document as SVG. If output_path is omitted, the raw SVG string is returned inline (useful for direct LLM consumption). Args: file_path, page (0-based, default 0), output_path (optional). It is categorised as a Read tool in the Hwp MCP Server, which means it retrieves data without modifying state.

How do I enforce a policy on render_hwp_page? +

Register the Hwp MCP server in PolicyLayer and add a rule for render_hwp_page: 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 Hwp. Nothing to install.

What risk level is render_hwp_page? +

render_hwp_page is a Read tool with low risk. Read-only tools are generally safe to allow by default.

Can I rate-limit render_hwp_page? +

Yes. Add a rate_limit block to the render_hwp_page 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.

How do I block render_hwp_page completely? +

Set action: deny in the PolicyLayer policy for render_hwp_page. 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.

What MCP server provides render_hwp_page? +

render_hwp_page is provided by the Hwp MCP server (treesoop/hwp-mcp). PolicyLayer sits as a proxy in front of this server to enforce policies before tool calls reach the server.

Enforce policy on every Hwp tool call.
