Create a new Word document Parameters: - file_path: Document save path
AI agents use create_document to create or update resources in Doc/docx — usually the action step of a workflow, after the agent has gathered context. Every call changes real data in your Doc/docx environment.
This tool creates new Word documents, which is a reversible write operation. While it doesn't modify existing data, it does create persistent file system artifacts. Severity is medium because the blast radius is limited to document creation; an agent could create many files or overwrite by reusing paths, but this is less severe than the destructive operations (delete_paragraph, delete_table_row, delete_text) also…
From the tool's definition The tool 'create_document' with description 'Create a new Word document' and parameter 'file_path: Document save path' creates new files. This is a write operation that modifies the filesystem by introducing new documents.
Documented attack patterns abuse exactly the kind of access create_document gives an agent:
PolicyLayer is an MCP gateway — it sits between your AI agents and Doc/docx, and nothing reaches the server without passing your rules. This is the rule we recommend for create_document:
{
"version": "1",
"default": "deny",
"tools": {
"create_document": {
"limits": [
{
"counter": "create_document_rate",
"window": "minute",
"max": 30,
"scope": "grant"
}
]
}
}
}create_document 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.

Create a new Word document Parameters: - file_path: Document save path. It is categorised as a Write tool in the Doc/docx MCP Server, which means it can create or modify data. Consider rate limits to prevent runaway writes.
Register the Doc/docx MCP server in PolicyLayer and add a rule for create_document: 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 Doc/docx. Nothing to install.
create_document 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 create_document 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 create_document. 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.
create_document is provided by the Doc/docx MCP server (meterlong/mcp-doc). PolicyLayer sits as a proxy in front of this server to enforce policies before tool calls reach the server.
Start from Doc/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.
