Copy all permissions from one role to another (full replacement).
AI agents use superset_role_copy_permissions 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 or modifies access control data by copying permissions between roles. While the operation is reversible (permissions can be reconfigured), it has significant blast radius: an AI agent misusing this could grant unintended privileges to roles, escalating access across the system or affecting multiple users whose access depends on that role.
From the tool's definition Tool description states: 'Copy all permissions from one role to another (full replacement).' This modifies role permissions, which is a reversible data change operation.
Documented attack patterns abuse exactly the kind of access superset_role_copy_permissions 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_copy_permissions:
{
"version": "1",
"default": "deny",
"tools": {
"superset_role_copy_permissions": {
"limits": [
{
"counter": "superset_role_copy_permissions_rate",
"window": "minute",
"max": 30,
"scope": "grant"
}
]
}
}
}superset_role_copy_permissions 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.

Copy all permissions from one role to another (full replacement). 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_copy_permissions: 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_copy_permissions 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_copy_permissions 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_copy_permissions. 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_copy_permissions 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.
