Apply paragraph formatting (alignment·indent·line_spacing) to the Nth paragraph in an .hwpx. Adds a new paraPr to header.xml and retargets the paragraph
AI agents use apply_hwp_paragraph_style to create or update resources in Hwp — usually the action step of a workflow, after the agent has gathered context. Every call changes real data in your Hwp environment.
This tool modifies document formatting properties (alignment, indent, line spacing) by adding/updating paragraph properties in the XML. These changes are reversible—formatting can be changed back or removed—making this a Write operation rather than Destructive. The impact is limited to visual presentation of a single paragraph without deleting content or executing arbitrary code.
From the tool's definition Tool description states it 'Apply paragraph formatting' and 'Adds a new paraPr to header.xml and retargets the paragraph', which are reversible modifications to document structure.
Documented attack patterns abuse exactly the kind of access apply_hwp_paragraph_style 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 apply_hwp_paragraph_style:
{
"version": "1",
"default": "deny",
"tools": {
"apply_hwp_paragraph_style": {
"limits": [
{
"counter": "apply_hwp_paragraph_style_rate",
"window": "minute",
"max": 30,
"scope": "grant"
}
]
}
}
}apply_hwp_paragraph_style stays usable, but capped — an agent stuck in a loop can't make hundreds of changes a minute. Everything else on the server is denied unless you say otherwise.

Apply paragraph formatting (alignment·indent·line_spacing) to the Nth paragraph in an .hwpx. Adds a new paraPr to header.xml and retargets the paragraph. It is categorised as a Write tool in the Hwp MCP Server, which means it can create or modify data. Consider rate limits to prevent runaway writes.
Register the Hwp MCP server in PolicyLayer and add a rule for apply_hwp_paragraph_style: 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.
apply_hwp_paragraph_style is a Write tool with medium risk. Write tools should be rate-limited to prevent accidental bulk modifications.
Yes. Add a rate_limit block to the apply_hwp_paragraph_style 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 apply_hwp_paragraph_style. 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.
apply_hwp_paragraph_style 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.
