AI agents use modify_local_table_structure 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.
This tool modifies existing table structures in local Word documents, which is a reversible write operation. It does not delete data (not Destructive), execute arbitrary code (not Execute), or handle financial data (not Financial).
From the tool's definition Tool description states '表格批量操作' (batch table operations) and 'modify_local_table_structure' indicates modification of table structures in local files.
Documented attack patterns abuse exactly the kind of access modify_local_table_structure 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 modify_local_table_structure:
{
"version": "1",
"default": "deny",
"tools": {
"modify_local_table_structure": {
"limits": [
{
"counter": "modify_local_table_structure_rate",
"window": "minute",
"max": 30,
"scope": "grant"
}
]
}
}
}modify_local_table_structure 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.

【本地表格批量操作工具】处理本地文件的表格操作. 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 modify_local_table_structure: 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.
modify_local_table_structure 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 modify_local_table_structure 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 modify_local_table_structure. 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.
modify_local_table_structure 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.
