AI agents call luogu_recommend_problems 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.
The tool recommends and suggests problems based on input parameters but does not create, modify, delete, or execute any operations. It only retrieves and presents data to the user, fitting the 'Read' category of querying and discovering data without side effects.
From the tool's definition Server is explicitly described as 'read-only MCP server for discovering and fetching Luogu problems'. Tool performs recommendation/search operations with 'search hints for further exploration', which is a discovery and retrieval function without side effects.

Register the Luogu MCP server in PolicyLayer and add a rule for luogu_recommend_problems: 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_recommend_problems 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_recommend_problems 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.
