AI agents use set_page_size to create or update resources in Docx_MCP_cj — usually the action step of a workflow, after the agent has gathered context. Every call changes real data in your Docx_MCP_cj environment.
Changing page size is a Write operation—it modifies document properties in a non-destructive, reversible manner. Users can undo or change the page size again. Medium severity because incorrect page sizes could affect document rendering or printing, but the change is easily correctable and doesn't delete or execute arbitrary code.
From the tool's definition Tool name 'set_page_size' combined with description '设置页面大小' (Chinese: 'set page size') indicates modification of document formatting properties. This is a reversible change to document metadata/layout.
Documented attack patterns abuse exactly the kind of access set_page_size gives an agent:
PolicyLayer is an MCP gateway — it sits between your AI agents and Docx_MCP_cj, and nothing reaches the server without passing your rules. This is the rule we recommend for set_page_size:
{
"version": "1",
"default": "deny",
"tools": {
"set_page_size": {
"limits": [
{
"counter": "set_page_size_rate",
"window": "minute",
"max": 30,
"scope": "grant"
}
]
}
}
}set_page_size 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.

设置页面大小. It is categorised as a Write tool in the Docx_MCP_cj MCP Server, which means it can create or modify data. Consider rate limits to prevent runaway writes.
Register the Docx_MCP_cj MCP server in PolicyLayer and add a rule for set_page_size: 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_MCP_cj. Nothing to install.
set_page_size 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_page_size 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_page_size. 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_page_size is provided by the Docx_MCP_cj MCP server (rockcj/docx_mcp_cj). PolicyLayer sits as a proxy in front of this server to enforce policies before tool calls reach the server.
