Get the base URL of the configured Superset instance.
AI agents call superset_get_base_url to retrieve information from MCP Superset without modifying anything — typically the context-gathering step in research, monitoring, and reporting workflows, before the agent takes action elsewhere.
This tool retrieves configuration metadata (a base URL) without modifying, executing, or deleting any data. It is a simple query operation that returns a read-only value used for constructing API endpoints. The blast radius if misused is minimal—an attacker would only learn the server's URL, which is typically non-sensitive deployment information.
From the tool's definition Tool name 'superset_get_base_url' and description 'Get the base URL of the configured Superset instance' indicate a retrieval operation with no side effects.
Documented attack patterns abuse exactly the kind of access superset_get_base_url 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_get_base_url:
{
"version": "1",
"default": "deny",
"tools": {
"superset_get_base_url": {}
}
}superset_get_base_url is read-only, so it stays allowed — but everything else on the server is denied unless you say otherwise.
Free to start. No card required.
Get the base URL of the configured Superset instance. It is categorised as a Read tool in the MCP Superset MCP Server, which means it retrieves data without modifying state.
Register the MCP Superset MCP server in PolicyLayer and add a rule for superset_get_base_url: 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_get_base_url is a Read tool with low risk. Read-only tools are generally safe to allow by default.
Yes. Add a rate_limit block to the superset_get_base_url 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_get_base_url. 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_get_base_url 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.
