Set table alignment: left, center, or right.
AI agents use set_table_alignment 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.
This tool modifies document formatting by changing table alignment, which is a reversible write operation. It does not execute arbitrary code, delete data, move funds, or cause irreversible damage. The change can be undone through standard document undo mechanisms or by setting a different alignment. Low severity because table formatting changes have minimal business impact and are easily reversible.
From the tool's definition Tool name 'set_table_alignment' and description 'Set table alignment: left, center, or right' indicate modification of document formatting properties.
Documented attack patterns abuse exactly the kind of access set_table_alignment 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 set_table_alignment:
{
"version": "1",
"default": "deny",
"tools": {
"set_table_alignment": {
"limits": [
{
"counter": "set_table_alignment_rate",
"window": "minute",
"max": 30,
"scope": "grant"
}
]
}
}
}set_table_alignment 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.

Set table alignment: left, center, or right. 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 set_table_alignment: 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.
set_table_alignment 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 set_table_alignment 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 set_table_alignment. 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.
set_table_alignment 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.
Free to start. No card required.
