合并多个Word文档。 Args: main_file_path: 主文档的完整路径或相对于输出目录的路径（合并后的文档将保存为该文件） files_to_merge: 要合并的文档路径列表 Returns: 操作结果信息
AI agents use merge_documents to create or update resources in Office Editor — usually the action step of a workflow, after the agent has gathered context. Every call changes real data in your Office Editor environment.
This is a Write operation because it creates or modifies data reversibly. It combines multiple input documents into a single output document without permanently destroying source files.
From the tool's definition Tool merges multiple Word documents by combining them into a main file. The description indicates it modifies/creates a document by combining inputs ("合并多个Word文档" / merge multiple Word documents) and saves the result ("合并后的文档将保存为该文件" / merged document will be…
Documented attack patterns abuse exactly the kind of access merge_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 merge_documents:
{
"version": "1",
"default": "deny",
"tools": {
"merge_documents": {
"limits": [
{
"counter": "merge_documents_rate",
"window": "minute",
"max": 30,
"scope": "grant"
}
]
}
}
}merge_documents 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 Office Editor MCP server in PolicyLayer and add a rule for merge_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.
merge_documents 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 merge_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 merge_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.
merge_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.
