向飞书云文档写入 Markdown 内容。将 Markdown 解析为飞书文档块（标题、列表、代码块、引用等），追加到文档末尾。适用于向已有文档批量写入结构化内容
AI agents use write_docx_content to create or update resources in Personal Knowledge MCP Server — usually the action step of a workflow, after the agent has gathered context. Every call changes real data in your Personal Knowledge MCP Server environment.
This tool creates or modifies data in cloud documents (Feishu) by appending Markdown content. It falls squarely into the Write category: it changes document state (adds content) but is reversible—appended content can be deleted and the document restored to a previous state.
From the tool's definition Tool description explicitly states '向飞书云文档写入' (write to Feishu cloud documents) and 'Markdown 解析为飞书文档块...追加到文档末尾' (parse Markdown into Feishu document blocks and append to document end).
Documented attack patterns abuse exactly the kind of access write_docx_content gives an agent:
PolicyLayer is an MCP gateway — it sits between your AI agents and Personal Knowledge MCP Server, and nothing reaches the server without passing your rules. This is the rule we recommend for write_docx_content:
{
"version": "1",
"default": "deny",
"tools": {
"write_docx_content": {
"limits": [
{
"counter": "write_docx_content_rate",
"window": "minute",
"max": 30,
"scope": "grant"
}
]
}
}
}write_docx_content 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.

Register the Personal Knowledge MCP Server MCP server in PolicyLayer and add a rule for write_docx_content: 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 Personal Knowledge MCP Server. Nothing to install.
write_docx_content 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 write_docx_content 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 write_docx_content. 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.
write_docx_content is provided by the Personal Knowledge MCP Server MCP server (kyodule/personal-knowledge-mcp). PolicyLayer sits as a proxy in front of this server to enforce policies before tool calls reach the server.
Start from Personal Knowledge MCP Server, add the rest of your stack, and see everything your agents can call. Then put policy on all of it.
