List all comments with their ID, author, date, and text.
AI agents call get_comments to retrieve information from Docx without modifying anything — typically the context-gathering step in research, monitoring, and reporting workflows, before the agent takes action elsewhere.
This tool queries and retrieves existing comment metadata (ID, author, date, text) from a Word document without altering, creating, or deleting any data. It is a straightforward read operation with minimal blast radius if misused by an agent — at worst, an agent could enumerate comments to extract information, but no document state changes occur.
From the tool's definition Tool name is 'get_comments' and description states it 'List all comments' — a pure retrieval operation with no modification or side effects.
Documented attack patterns abuse exactly the kind of access get_comments gives an agent:
PolicyLayer is an MCP gateway — it sits between your AI agents and Docx, and nothing reaches the server without passing your rules. This is the rule we recommend for get_comments:
{
"version": "1",
"default": "deny",
"tools": {
"get_comments": {}
}
}get_comments is read-only, so it stays allowed — but everything else on the server is denied unless you say otherwise.
Free to start. No card required.
List all comments with their ID, author, date, and text. It is categorised as a Read tool in the Docx MCP Server, which means it retrieves data without modifying state.
Register the Docx MCP server in PolicyLayer and add a rule for get_comments: 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. Nothing to install.
get_comments is a Read tool with low risk. Read-only tools are generally safe to allow by default.
Yes. Add a rate_limit block to the get_comments 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 get_comments. 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.
get_comments is provided by the Docx MCP server (securityronin/docx-mcp). PolicyLayer sits as a proxy in front of this server to enforce policies before tool calls reach the server.
Start from 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.
