AI agents use edit_text_frame to create or update resources in InDesign UXP MCP Server — usually the action step of a workflow, after the agent has gathered context. Every call changes real data in your InDesign UXP MCP Server environment.
This tool modifies content within a document (text frame) but does not delete or permanently destroy data. The change is reversible through undo/redo functionality typical in InDesign. While it can alter a user's document, the blast radius is limited to the specific text frame being edited and does not affect the entire project structure, styles, or other elements.
From the tool's definition Tool name is 'edit_text_frame' and description states 'Edit an existing text frame'. The verb 'edit' indicates modification of existing content.
Documented attack patterns abuse exactly the kind of access edit_text_frame gives an agent:
PolicyLayer is an MCP gateway — it sits between your AI agents and InDesign UXP MCP Server, and nothing reaches the server without passing your rules. This is the rule we recommend for edit_text_frame:
{
"version": "1",
"default": "deny",
"tools": {
"edit_text_frame": {
"limits": [
{
"counter": "edit_text_frame_rate",
"window": "minute",
"max": 30,
"scope": "grant"
}
]
}
}
}edit_text_frame 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.

Edit an existing text frame. It is categorised as a Write tool in the InDesign UXP MCP Server MCP Server, which means it can create or modify data. Consider rate limits to prevent runaway writes.
Register the InDesign UXP MCP Server MCP server in PolicyLayer and add a rule for edit_text_frame: 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 InDesign UXP MCP Server. Nothing to install.
edit_text_frame 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 edit_text_frame 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 edit_text_frame. 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.
edit_text_frame is provided by the InDesign UXP MCP Server MCP server (theloniuser/indesign-uxp-server). PolicyLayer sits as a proxy in front of this server to enforce policies before tool calls reach the server.
