AI agents use format_table 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.
Formatting a table modifies the document's structure and presentation (cell styling, borders, alignment, etc.) but does not delete data or execute arbitrary code. This is a reversible modification operation characteristic of Write category. Severity is medium because improper formatting could affect document usability or professional appearance, but the changes are non-destructive and can be undone.
From the tool's definition Tool name 'format_table' with description '格式化表格' (format table in Chinese). The server context shows it operates on Word document tables as part of a suite that includes 'add_table', 'add_table_row', 'apply_modifications_to_document'—all Write operations…
Documented attack patterns abuse exactly the kind of access format_table 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 format_table:
{
"version": "1",
"default": "deny",
"tools": {
"format_table": {
"limits": [
{
"counter": "format_table_rate",
"window": "minute",
"max": 30,
"scope": "grant"
}
]
}
}
}format_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.

格式化表格. 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 format_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_MCP_cj. Nothing to install.
format_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 format_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 format_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.
format_table 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.
