Add a section break at a paragraph. break_type: nextPage/continuous/evenPage/oddPage.
AI agents use add_section_break 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 structure reversibly by inserting section breaks—a non-destructive write operation. It alters the document layout and formatting but does not delete data, execute code, or cause irreversible changes. Confidence is high because the action is explicit and limited in scope.
From the tool's definition Tool name 'add_section_break' and description 'Add a section break at a paragraph' indicate structural modification of document content.
Documented attack patterns abuse exactly the kind of access add_section_break 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_section_break:
{
"version": "1",
"default": "deny",
"tools": {
"add_section_break": {
"limits": [
{
"counter": "add_section_break_rate",
"window": "minute",
"max": 30,
"scope": "grant"
}
]
}
}
}add_section_break 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.

Add a section break at a paragraph. break_type: nextPage/continuous/evenPage/oddPage. 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_section_break: 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_section_break 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_section_break 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_section_break. 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_section_break 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.
