WHAT IT DOES

What get_relational_metadata does on SAP Datasphere MCP Server

AI agents call get_relational_metadata to retrieve information from SAP Datasphere MCP Server without modifying anything — typically the context-gathering step in research, monitoring, and reporting workflows, before the agent takes action elsewhere.

THE RISK

Low Risk

Why get_relational_metadata needs a policy

This tool performs schema metadata discovery and inspection on SAP Datasphere assets. While it is read-only with no side effects, the severity is elevated from 'low' to 'medium' because metadata exposure in enterprise data platforms can reveal sensitive information about data structure, table names, relationships, and field definitions that could inform further attacks or unauthorized data access.

From the tool's definition Tool retrieves metadata information: 'Retrieve CSDL metadata for relational consumption', 'Returns complete schema information including tables, columns, data types, primary/foreign keys, and relationships'.

POLICY

How to control get_relational_metadata

PolicyLayer is an MCP gateway — it sits between your AI agents and SAP Datasphere MCP Server, and nothing reaches the server without passing your rules. This is the rule we recommend for get_relational_metadata:

policy.json

{
  "version": "1",
  "default": "deny",
  "tools": {
    "get_relational_metadata": {}
  }
}

get_relational_metadata is read-only, so it stays allowed — but everything else on the server is denied unless you say otherwise.

Create a free account and register SAP Datasphere MCP Server — nothing to install.
Add this policy — paste it, or build it visually.
Point your MCP client (Claude, Cursor, anything) at your gateway URL.
