AI agents call get_hwp_field_value 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.
This tool retrieves field values from HWP documents without modifying, deleting, or executing code. It is a straightforward data query operation that returns information. The low severity reflects minimal blast radius—an AI agent misusing this tool can only read field data, which poses no destructive or financial risk.
From the tool's definition Tool name 'get_hwp_field_value' and description 'Get a Hancom field' indicate a retrieval operation. The verb 'Get' and the read-only nature of field value extraction confirm this is a query operation with no side effects.
Documented attack patterns abuse exactly the kind of access get_hwp_field_value 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 get_hwp_field_value:
{
"version": "1",
"default": "deny",
"tools": {
"get_hwp_field_value": {}
}
}get_hwp_field_value is read-only, so it stays allowed — but everything else on the server is denied unless you say otherwise.

Get a Hancom field. It is categorised as a Read tool in the Hwp MCP Server, which means it retrieves data without modifying state.
Register the Hwp MCP server in PolicyLayer and add a rule for get_hwp_field_value: 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.
get_hwp_field_value 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 get_hwp_field_value 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 get_hwp_field_value. 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.
get_hwp_field_value 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.
