Enable or disable write permissions for specific categories. Scopes by risk: HIGH (users, contacts, surveys — unrecoverable), MEDIUM (surveyDesign — reprogrammable), LOW (questionsAndBlocks — trash recoverable), MINIMAL (distributions). Use this to grant only the minimum permissions needed.
AI agents use set_write_scopes to create or update resources in Qualtrics MCP Server — usually the action step of a workflow, after the agent has gathered context. Every call changes real data in your Qualtrics MCP Server environment.
While this tool itself is a permission-control mechanism (which could be classified as Execute), its primary function is to grant or revoke write access to other tools that modify data. The tool has direct side effects: enabling HIGH-risk write scopes allows creation/modification of surveys, contacts, and user data.
From the tool's definition Tool enables or disables write permissions for categories including 'users, contacts, surveys' which are described as 'unrecoverable', and 'surveyDesign' which is 'reprogrammable'.
Documented attack patterns abuse exactly the kind of access set_write_scopes gives an agent:
PolicyLayer is an MCP gateway — it sits between your AI agents and Qualtrics MCP Server, and nothing reaches the server without passing your rules. This is the rule we recommend for set_write_scopes:
{
"version": "1",
"default": "deny",
"tools": {
"set_write_scopes": {
"limits": [
{
"counter": "set_write_scopes_rate",
"window": "minute",
"max": 30,
"scope": "grant"
}
]
}
}
}set_write_scopes 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.

Enable or disable write permissions for specific categories. Scopes by risk: HIGH (users, contacts, surveys — unrecoverable), MEDIUM (surveyDesign — reprogrammable), LOW (questionsAndBlocks — trash recoverable), MINIMAL (distributions). Use this to grant only the minimum permissions needed. It is categorised as a Write tool in the Qualtrics MCP Server MCP Server, which means it can create or modify data. Consider rate limits to prevent runaway writes.
Register the Qualtrics MCP Server MCP server in PolicyLayer and add a rule for set_write_scopes: 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 Qualtrics MCP Server. Nothing to install.
set_write_scopes 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 set_write_scopes 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 set_write_scopes. 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.
set_write_scopes is provided by the Qualtrics MCP Server MCP server (yrvelez/qualtrics-mcp-server). PolicyLayer sits as a proxy in front of this server to enforce policies before tool calls reach the server.
Start from Qualtrics MCP Server, add the rest of your stack, and see everything your agents can call. Then put policy on all of it.
