AI agents use word_insert_text to create or update resources in Mcp Windows — usually the action step of a workflow, after the agent has gathered context. Every call changes real data in your Mcp Windows environment.
This tool modifies a Word document by inserting text at the current cursor position. This is a reversible write operation—text can be deleted or edited afterward. It does not execute code, delete data irreversibly, or move money.
From the tool's definition Tool name is 'word_insert_text' with description 'Insert text at the current selection in Word'. The verb 'insert' indicates creation/modification of document content.

PolicyLayer is an MCP gateway — it sits between your AI agents and Mcp Windows, and nothing reaches the server without passing your rules. This is the rule we recommend for word_insert_text:
{
"version": "1",
"default": "deny",
"tools": {
"word_insert_text": {
"limits": [
{
"counter": "word_insert_text_rate",
"window": "minute",
"max": 30,
"scope": "grant"
}
]
}
}
}word_insert_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.
