AI agents call compare_documents to retrieve information from Office Editor without modifying anything — typically the context-gathering step in research, monitoring, and reporting workflows, before the agent takes action elsewhere.
This tool reads two documents and compares their contents, returning a diff result. It does not modify, create, or delete any data — it is purely a read/query operation. Severity is low as the worst case is reading file contents from the filesystem.
From the tool's definition 比较两个文档的内容差异 (Compare the content differences between two documents); returns a dictionary containing comparison results
Documented attack patterns abuse exactly the kind of access compare_documents gives an agent:
PolicyLayer is an MCP gateway — it sits between your AI agents and Office Editor, and nothing reaches the server without passing your rules. This is the rule we recommend for compare_documents:
{
"version": "1",
"default": "deny",
"tools": {
"compare_documents": {}
}
}compare_documents is read-only, so it stays allowed — but everything else on the server is denied unless you say otherwise.

Register the Office Editor MCP server in PolicyLayer and add a rule for compare_documents: 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 Office Editor. Nothing to install.
compare_documents 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 compare_documents 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 compare_documents. 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.
compare_documents is provided by the Office Editor MCP server (thewdy/office-editor-mcp). PolicyLayer sits as a proxy in front of this server to enforce policies before tool calls reach the server.
