Merge horizontal cells in a row of a table by setting colSpan on the first cell and removing the absorbed cells. Args: file_path, table_index, row, col_start, col_count (>=2), output_path (optional).
AI agents use merge_hwp_cells_horizontal 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 creates a reversible change to document structure (merging table cells) without permanently destroying data or executing arbitrary code. While it modifies the document, the operation is not destructive—merged cells can be unmerged. This qualifies as Write rather than Destructive.
From the tool's definition Tool modifies table structure by merging cells (setting colSpan and removing absorbed cells). Description explicitly states 'Merge horizontal cells in a row' which is a reversible structural modification to a document.
Documented attack patterns abuse exactly the kind of access merge_hwp_cells_horizontal 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 merge_hwp_cells_horizontal:
{
"version": "1",
"default": "deny",
"tools": {
"merge_hwp_cells_horizontal": {
"limits": [
{
"counter": "merge_hwp_cells_horizontal_rate",
"window": "minute",
"max": 30,
"scope": "grant"
}
]
}
}
}merge_hwp_cells_horizontal 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.

Merge horizontal cells in a row of a table by setting colSpan on the first cell and removing the absorbed cells. Args: file_path, table_index, row, col_start, col_count (>=2), output_path (optional). 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 merge_hwp_cells_horizontal: 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.
merge_hwp_cells_horizontal 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 merge_hwp_cells_horizontal 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 merge_hwp_cells_horizontal. 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.
merge_hwp_cells_horizontal 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.
