Simplified helper to create a Likert/matrix question with statements and scale points.
AI agents use add_matrix_question 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.
This tool creates new survey questions (matrix/Likert format), which modifies survey data reversibly. It is a Write operation because questions can be edited or deleted. Severity is medium because misuse could add malformed or misleading questions to surveys, affecting data collection quality, but the impact is limited to a single survey component and is reversible.
From the tool's definition Tool name 'add_matrix_question' and description 'create a Likert/matrix question' indicate data creation within surveys. The server description confirms it enables 'survey creation, question management' through natural language control.
Documented attack patterns abuse exactly the kind of access add_matrix_question 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 add_matrix_question:
{
"version": "1",
"default": "deny",
"tools": {
"add_matrix_question": {
"limits": [
{
"counter": "add_matrix_question_rate",
"window": "minute",
"max": 30,
"scope": "grant"
}
]
}
}
}add_matrix_question 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.

Simplified helper to create a Likert/matrix question with statements and scale points. 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 add_matrix_question: 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.
add_matrix_question 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_matrix_question 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_matrix_question. 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_matrix_question 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.
Free to start. No card required.
