List all available business categories in the Qwery taxonomy. Categories are organized by domain (software, developer-tools, hospitality, finance, etc.).
AI agents call categories to retrieve information from Qwery MCP Server without modifying anything — typically the context-gathering step in research, monitoring, and reporting workflows, before the agent takes action elsewhere.
This tool performs a read-only query operation that retrieves structured reference data (taxonomy of business categories). There are no side effects, no data creation or modification, and no irreversible operations. The tool simply lists information, consistent with standard Read category tools like 'list' or 'fetch'.

List all available business categories in the Qwery taxonomy. Categories are organized by domain (software, developer-tools, hospitality, finance, etc.). It is categorised as a Read tool in the Qwery MCP Server MCP Server, which means it retrieves data without modifying state.
Register the Qwery MCP Server MCP server in PolicyLayer and add a rule for 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 Qwery MCP Server. Nothing to install.
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 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 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.
categories is provided by the Qwery MCP Server MCP server (kingroyalabstergo-agent/qwery-mcp). PolicyLayer sits as a proxy in front of this server to enforce policies before tool calls reach the server.
