AI agents use find_and_replace_text 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 tool modifies document content by replacing text within a Word file. It is a reversible write operation (original text is overwritten but the document can be edited again). No code execution, deletion, or financial action is involved. Severity is medium because an AI agent could inadvertently alter important document content at scale if misused.
From the tool's definition 查找并替换文本 (find and replace text in Word document); parameters include find_text, replace_text, and save (defaults to True)
Documented attack patterns abuse exactly the kind of access find_and_replace_text 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 find_and_replace_text:
{
"version": "1",
"default": "deny",
"tools": {
"find_and_replace_text": {
"limits": [
{
"counter": "find_and_replace_text_rate",
"window": "minute",
"max": 30,
"scope": "grant"
}
]
}
}
}find_and_replace_text 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.

It is categorised as a Write tool in the Office Editor MCP Server, which means it can create or modify data. Consider rate limits to prevent runaway writes.
Register the Office Editor MCP server in PolicyLayer and add a rule for find_and_replace_text: 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.
find_and_replace_text 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 find_and_replace_text 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 find_and_replace_text. 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.
find_and_replace_text 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.
