Cache-Statistiken: Trefferquote, gespeicherte Eintraege, gesparte API-Calls.
AI agents call news_cache_stats to retrieve information from Pypi:news Monitor without modifying anything — typically the context-gathering step in research, monitoring, and reporting workflows, before the agent takes action elsewhere.
This tool retrieves statistical information about cache performance with no side effects, data modification, code execution, or destructive capabilities. It is a read-only query of existing cache metrics, making it a Read category tool with low severity risk.
From the tool's definition Tool name 'news_cache_stats' and description 'Cache-Statistiken: Trefferquote, gespeicherte Eintraege, gesparte API-Calls' (Cache statistics: hit rate, stored entries, saved API calls) indicate retrieval and querying of cache performance metrics only.

Cache-Statistiken: Trefferquote, gespeicherte Eintraege, gesparte API-Calls. It is categorised as a Read tool in the Pypi:news Monitor MCP Server, which means it retrieves data without modifying state.
Register the Pypi:news Monitor MCP server in PolicyLayer and add a rule for news_cache_stats: 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 Pypi:news Monitor. Nothing to install.
news_cache_stats 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 news_cache_stats 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 news_cache_stats. 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.
news_cache_stats is provided by the Pypi:news Monitor MCP server (pypi:news-monitor-mcp). PolicyLayer sits as a proxy in front of this server to enforce policies before tool calls reach the server.
