AI agents use add_worksheet 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 new worksheet objects within an Excel file, which is a reversible modification (sheets can be deleted). It does not execute arbitrary code, delete data, or move money. It is a Write operation because it adds/creates a new data structure. Severity is medium because misuse could create many worksheets or corrupt a workbook structure, but the impact is limited to a single file and is reversible.
From the tool's definition Tool name 'add_worksheet' and description state it 'adds a new worksheet' to an Excel workbook. The function takes a file_path and sheet_name as arguments and returns operation result information, indicating it creates new data structures within an existing…
Documented attack patterns abuse exactly the kind of access add_worksheet 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 add_worksheet:
{
"version": "1",
"default": "deny",
"tools": {
"add_worksheet": {
"limits": [
{
"counter": "add_worksheet_rate",
"window": "minute",
"max": 30,
"scope": "grant"
}
]
}
}
}add_worksheet 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.

Register the Office Editor MCP server in PolicyLayer and add a rule for add_worksheet: 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.
add_worksheet 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 add_worksheet 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 add_worksheet. 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.
add_worksheet 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.
