Create a new role (without permissions). Permissions are added via role_permission_add.
AI agents use superset_role_create to create or update resources in MCP Superset — usually the action step of a workflow, after the agent has gathered context. Every call changes real data in your MCP Superset environment.
This tool creates a new role, which is a write operation that modifies the authorization/security configuration of the Superset system. Role creation is reversible (roles can be deleted), so it falls under Write rather than Destructive. However, the severity is high because creating unauthorized roles could grant unwanted access permissions to users, affecting system security and data access controls.
From the tool's definition Tool name 'superset_role_create' and description 'Create a new role' indicate irreversible creation of a new security role object in Superset.
Documented attack patterns abuse exactly the kind of access superset_role_create gives an agent:
PolicyLayer is an MCP gateway — it sits between your AI agents and MCP Superset, and nothing reaches the server without passing your rules. This is the rule we recommend for superset_role_create:
{
"version": "1",
"default": "deny",
"tools": {
"superset_role_create": {
"limits": [
{
"counter": "superset_role_create_rate",
"window": "minute",
"max": 30,
"scope": "grant"
}
]
}
}
}superset_role_create 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.

Create a new role (without permissions). Permissions are added via role_permission_add. It is categorised as a Write tool in the MCP Superset MCP Server, which means it can create or modify data. Consider rate limits to prevent runaway writes.
Register the MCP Superset MCP server in PolicyLayer and add a rule for superset_role_create: 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 MCP Superset. Nothing to install.
superset_role_create 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 superset_role_create 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 superset_role_create. 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.
superset_role_create is provided by the MCP Superset MCP server (mcp-superset). PolicyLayer sits as a proxy in front of this server to enforce policies before tool calls reach the server.
Start from MCP Superset, 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.
