AI agents use add_animation 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.
The tool name and context of an office document editor server indicate this creates or modifies presentation animations, which is reversible data modification. This falls under Write category. Severity is low because animations are cosmetic/presentation enhancements with minimal business impact.
From the tool's definition Tool name 'add_animation' suggests modifying presentation content (animations are slide effects in PowerPoint). Sibling tools like 'add_slide', 'add_text_box', and 'add_slide_notes' all perform reversible content modifications.
Documented attack patterns abuse exactly the kind of access add_animation 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 add_animation:
{
"version": "1",
"default": "deny",
"tools": {
"add_animation": {
"limits": [
{
"counter": "add_animation_rate",
"window": "minute",
"max": 30,
"scope": "grant"
}
]
}
}
}add_animation 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.

add_animation. 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 add_animation: 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.
add_animation 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 add_animation 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 add_animation. 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.
add_animation 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.
