라벨 어휘 목록 + 카탈로그 signature 를 반환한다 (signature 가 같으면 캐시 재사용).
AI agents call list_labels to retrieve information from Assetcache without modifying anything — typically the context-gathering step in research, monitoring, and reporting workflows, before the agent takes action elsewhere.
This tool retrieves metadata about available labels and a catalog signature for caching purposes. It performs a read-only query with no ability to modify, delete, execute code, or trigger external operations. The blast radius of misuse is minimal—an agent querying labels cannot cause harm to assets or system state.
From the tool's definition Tool name 'list_labels' and description 'returns label vocabulary list + catalog signature' indicate data retrieval with no modification or side effects. The mention of signature comparison for cache reuse confirms this is a query operation.

라벨 어휘 목록 + 카탈로그 signature 를 반환한다 (signature 가 같으면 캐시 재사용). It is categorised as a Read tool in the Assetcache MCP Server, which means it retrieves data without modifying state.
Register the Assetcache MCP server in PolicyLayer and add a rule for list_labels: 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 Assetcache. Nothing to install.
list_labels 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 list_labels 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 list_labels. 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.
list_labels is provided by the Assetcache MCP server (v0o0v/assetcache-mcp). PolicyLayer sits as a proxy in front of this server to enforce policies before tool calls reach the server.
