Clear all cached data
AI agents call clear_cache to permanently remove resources in Crypto MCP Server — typically in cleanup and lifecycle workflows. It does its job in a single call, and there is no undo.
Clearing all cached data is an irreversible action; once the cache is purged, previously cached market data (prices, OHLCV, order books, etc.) cannot be recovered from the cache. While the underlying data can be re-fetched from exchanges, the act itself is irreversible and could cause temporary denial of cached responses, increased API load, and rate-limiting issues.

Attacks that exploit this kind of access
Clear all cached data. It is categorised as a Destructive tool in the Crypto MCP Server MCP Server, which means it can permanently delete or destroy data. Block by default and require explicit approval.
Register the Crypto MCP Server MCP server in PolicyLayer and add a rule for clear_cache: 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 Crypto MCP Server. Nothing to install.
clear_cache is a Destructive tool with critical risk. Critical-risk tools should be blocked by default and only enabled with explicit human approval.
Yes. Add a rate_limit block to the clear_cache 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 clear_cache. 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.
clear_cache is provided by the Crypto MCP Server MCP server (kamatalarajeev/mcp). PolicyLayer sits as a proxy in front of this server to enforce policies before tool calls reach the server.
