Insert a new table after a paragraph with tracked insertion.
AI agents use add_table to create or update resources in Docx — usually the action step of a workflow, after the agent has gathered context. Every call changes real data in your Docx environment.
The tool creates and adds new content (a table) to a document, modifying its structure reversibly. This is a write operation—content can be undone or deleted. It does not execute arbitrary code, delete data irreversibly, or trigger financial transactions. The 'tracked insertion' feature suggests the change is recorded in the document's change tracking system, making it auditable and reversible.
From the tool's definition Tool description states 'Insert a new table' and 'tracked insertion', indicating creation of new document structure.
Documented attack patterns abuse exactly the kind of access add_table gives an agent:
PolicyLayer is an MCP gateway — it sits between your AI agents and Docx, and nothing reaches the server without passing your rules. This is the rule we recommend for add_table:
{
"version": "1",
"default": "deny",
"tools": {
"add_table": {
"limits": [
{
"counter": "add_table_rate",
"window": "minute",
"max": 30,
"scope": "grant"
}
]
}
}
}add_table 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.

Insert a new table after a paragraph with tracked insertion. It is categorised as a Write tool in the Docx MCP Server, which means it can create or modify data. Consider rate limits to prevent runaway writes.
Register the Docx MCP server in PolicyLayer and add a rule for add_table: 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 Docx. Nothing to install.
add_table 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_table 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_table. 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_table is provided by the Docx MCP server (securityronin/docx-mcp). PolicyLayer sits as a proxy in front of this server to enforce policies before tool calls reach the server.
Start from Docx, add the rest of your stack, and see everything your agents can call. Then put policy on all of it.
