在Excel工作簿中插入空列。 Args: file_path: Excel工作簿的完整路径或相对于输出目录的路径 sheet_name: 工作表名称 col_idx: 要插入列的位置（从1开始） Returns: 操作结果信息
AI agents use insert_column to create or update resources in Office Editor — usually the action step of a workflow, after the agent has gathered context. Every call changes real data in your Office Editor environment.
This tool creates/modifies spreadsheet structure by inserting columns, which is reversible (columns can be deleted). It does not execute arbitrary code, delete data, or involve financial operations. It qualifies as Write rather than Execute because the effect is deterministic spreadsheet modification, not conditional execution of external operations.
From the tool's definition Tool description states it inserts empty columns into Excel workbooks (插入空列). The function parameters (file_path, sheet_name, col_idx) indicate structural modification of spreadsheet data. The return value confirms an operation result is returned.
Documented attack patterns abuse exactly the kind of access insert_column gives an agent:
PolicyLayer is an MCP gateway — it sits between your AI agents and Office Editor, and nothing reaches the server without passing your rules. This is the rule we recommend for insert_column:
{
"version": "1",
"default": "deny",
"tools": {
"insert_column": {
"limits": [
{
"counter": "insert_column_rate",
"window": "minute",
"max": 30,
"scope": "grant"
}
]
}
}
}insert_column 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.

在Excel工作簿中插入空列。 Args: file_path: Excel工作簿的完整路径或相对于输出目录的路径 sheet_name: 工作表名称 col_idx: 要插入列的位置（从1开始） Returns: 操作结果信息. It is categorised as a Write tool in the Office Editor MCP Server, which means it can create or modify data. Consider rate limits to prevent runaway writes.
Register the Office Editor MCP server in PolicyLayer and add a rule for insert_column: 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 Office Editor. Nothing to install.
insert_column 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 insert_column 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 insert_column. 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.
insert_column is provided by the Office Editor MCP server (thewdy/office-editor-mcp). PolicyLayer sits as a proxy in front of this server to enforce policies before tool calls reach the server.
