AI agents call cache_stats to retrieve information from Coin without modifying anything — typically the context-gathering step in research, monitoring, and reporting workflows, before the agent takes action elsewhere.
With no description provided, confidence is moderately reduced. However, the name strongly suggests a diagnostic/informational function that queries cache state. No evidence of side effects, data modification, execution, destruction, or financial impact. Classified as Read with low severity since it merely retrieves internal metrics.
From the tool's definition Tool name 'cache_stats' with empty description; based on naming convention in a market-data server context, this appears to retrieve cache statistics/metrics rather than modify data.
Attacks that exploit this kind of access
cache_stats. It is categorised as a Read tool in the Coin MCP Server, which means it retrieves data without modifying state.
Register the Coin MCP server in PolicyLayer and add a rule for 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 Coin. Nothing to install.
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 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 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.
cache_stats is provided by the Coin MCP server (sweetcornna/coin-mcp). PolicyLayer sits as a proxy in front of this server to enforce policies before tool calls reach the server.
