AI agents call luogu_list_algorithm_topics to retrieve information from Luogu without modifying anything — typically the context-gathering step in research, monitoring, and reporting workflows, before the agent takes action elsewhere.
This tool retrieves and enumerates metadata about algorithm topics and tags. It performs no modifications, deletions, code execution, or financial operations. The action is purely informational and queries existing data structures with no side effects.
From the tool's definition Tool name 'luogu_list_algorithm_topics' and description 'List canonical algorithm topics' indicates a retrieval operation. Server description explicitly states it is 'read-only'. The tool lists/enumerates data with no side effects.
Attacks that exploit this kind of access
List canonical algorithm topics, aliases, and known Luogu tag ids used by the high-level topic search route. It is categorised as a Read tool in the Luogu MCP Server, which means it retrieves data without modifying state.
Register the Luogu MCP server in PolicyLayer and add a rule for luogu_list_algorithm_topics: 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 Luogu. Nothing to install.
luogu_list_algorithm_topics 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 luogu_list_algorithm_topics 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 luogu_list_algorithm_topics. 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.
luogu_list_algorithm_topics is provided by the Luogu MCP server (kaiserunix/luogu-mcp-server). PolicyLayer sits as a proxy in front of this server to enforce policies before tool calls reach the server.
