AI agents call luogu_get_capabilities 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 simply queries and reports the status of available capabilities without side effects. It retrieves static information about system capabilities and authentication requirements. No data is modified, deleted, or executed. This is a straightforward informational/introspection tool, consistent with the server's read-only nature.
From the tool's definition Tool name and description indicate a read-only capability reporting function: 'Report which... capabilities are available'. No data creation, modification, deletion, or execution of arbitrary operations.
Attacks that exploit this kind of access

Register the Luogu MCP server in PolicyLayer and add a rule for luogu_get_capabilities: 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_get_capabilities 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_get_capabilities 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_get_capabilities. 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_get_capabilities 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.
