Get column definitions for a specific dataset
AI agents call get_dataset_schema to retrieve information from Superset MCP Server without modifying anything — typically the context-gathering step in research, monitoring, and reporting workflows, before the agent takes action elsewhere.
This tool retrieves metadata about dataset structure (column definitions) without executing queries, modifying data, or triggering side effects. It is a passive information-gathering operation typical of Read-category tools. The context of a Superset analytics server confirms this is a standard schema inspection utility.
From the tool's definition Tool name 'get_dataset_schema' and description 'Get column definitions for a specific dataset' indicate a data retrieval operation with no modification, deletion, or execution of code. Returns schema metadata only.
Attacks that exploit this kind of access
Get column definitions for a specific dataset. It is categorised as a Read tool in the Superset MCP Server MCP Server, which means it retrieves data without modifying state.
Register the Superset MCP Server MCP server in PolicyLayer and add a rule for get_dataset_schema: 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 Superset MCP Server. Nothing to install.
get_dataset_schema 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 get_dataset_schema 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 get_dataset_schema. 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.
get_dataset_schema is provided by the Superset MCP Server MCP server (okybaguslukmana/superset-mcp). PolicyLayer sits as a proxy in front of this server to enforce policies before tool calls reach the server.
