Discover available command categories and get an overview of what each category does. Use this to find commands for a specific task.
AI agents call hana_discover_categories to retrieve information from SAP HANA CLI without modifying anything — typically the context-gathering step in research, monitoring, and reporting workflows, before the agent takes action elsewhere.
This is a pure informational/discovery tool that queries and returns categorical metadata about available commands. There are no side effects, data modification, code execution, or destructive operations. It falls squarely into the Read category with low severity due to minimal blast radius.
From the tool's definition Tool is described as 'Discover available command categories and get an overview of what each category does' — it retrieves and lists metadata about available commands without executing them or modifying data.

Discover available command categories and get an overview of what each category does. Use this to find commands for a specific task. It is categorised as a Read tool in the SAP HANA CLI MCP Server, which means it retrieves data without modifying state.
Register the SAP HANA CLI MCP server in PolicyLayer and add a rule for hana_discover_categories: 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 SAP HANA CLI. Nothing to install.
hana_discover_categories 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 hana_discover_categories 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 hana_discover_categories. 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.
hana_discover_categories is provided by the SAP HANA CLI MCP server (hana-cli). PolicyLayer sits as a proxy in front of this server to enforce policies before tool calls reach the server.
