Saves the currently active Word document.
AI agents use word_saveActiveDocument to create or update resources in MCP Office Interop Word Server — usually the action step of a workflow, after the agent has gathered context. Every call changes real data in your MCP Office Interop Word Server environment.
Saving a document is a reversible write operation that commits in-memory changes to persistent storage. While it modifies the file system state, the changes themselves are typically not destructive (the previous version may still exist as backups or recovery files, and unsaved changes can be re-edited).
From the tool's definition Tool name 'word_saveActiveDocument' and description 'Saves the currently active Word document' indicate a write operation that persists document modifications to disk.
Documented attack patterns abuse exactly the kind of access word_saveActiveDocument gives an agent:
PolicyLayer is an MCP gateway — it sits between your AI agents and MCP Office Interop Word Server, and nothing reaches the server without passing your rules. This is the rule we recommend for word_saveActiveDocument:
{
"version": "1",
"default": "deny",
"tools": {
"word_saveActiveDocument": {
"limits": [
{
"counter": "word_saveactivedocument_rate",
"window": "minute",
"max": 30,
"scope": "grant"
}
]
}
}
}word_saveActiveDocument 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.
