AI agents use hwp_replace_text to create or update resources in HWP MCP Server — usually the action step of a workflow, after the agent has gathered context. Every call changes real data in your HWP MCP Server environment.
This tool modifies document content by finding and replacing text, which is a reversible write operation. It does not execute code, delete data irreversibly, move money, or cause external side effects beyond document manipulation. While the replace_all parameter could affect multiple instances, the operation remains reversible (undo available in document editors).
From the tool's definition Tool name 'hwp_replace_text' and description '문서에서 텍스트를 찾아 바꿉니다' (finds and replaces text in document). Parameters include 'find' (text to find), 'replace' (text to replace with), and 'replace_all' (replace all occurrences, default True).
Documented attack patterns abuse exactly the kind of access hwp_replace_text gives an agent:
PolicyLayer is an MCP gateway — it sits between your AI agents and HWP MCP Server, and nothing reaches the server without passing your rules. This is the rule we recommend for hwp_replace_text:
{
"version": "1",
"default": "deny",
"tools": {
"hwp_replace_text": {
"limits": [
{
"counter": "hwp_replace_text_rate",
"window": "minute",
"max": 30,
"scope": "grant"
}
]
}
}
}hwp_replace_text 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.

문서에서 텍스트를 찾아 바꿉니다. Args: find: 찾을 텍스트 replace: 바꿀 텍스트 replace_all: 모두 바꾸기 여부 (기본값: True) Returns: str: 결과 메시지. It is categorised as a Write tool in the HWP MCP Server MCP Server, which means it can create or modify data. Consider rate limits to prevent runaway writes.
Register the HWP MCP Server MCP server in PolicyLayer and add a rule for hwp_replace_text: 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 MCP Server. Nothing to install.
hwp_replace_text 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 hwp_replace_text 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 hwp_replace_text. 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.
hwp_replace_text is provided by the HWP MCP Server MCP server (jkf87/hwp-mcp). PolicyLayer sits as a proxy in front of this server to enforce policies before tool calls reach the server.
Start from HWP MCP Server, add the rest of your stack, and see everything your agents can call. Then put policy on all of it.
