compare · Cryptosense MCP: Risk & Policy

WHAT IT DOES

What compare does on Cryptosense

AI agents call compare to retrieve information from Cryptosense without modifying anything — typically the context-gathering step in research, monitoring, and reporting workflows, before the agent takes action elsewhere.

WHY IT NEEDS A POLICY

Why compare needs a policy

Given the server's core function of providing 'real-time crypto market intelligence' and the pattern of sibling tools (get_info, check_worker_status, create_api_key), 'compare' most likely compares crypto prices or portfolio metrics — a read operation with no side effects.

From the tool's definition Tool named 'compare' on a crypto market intelligence server with sibling tools that are read-only (get_prices, trending_coins, market_overview, etc.). The server's stated purpose is 'Get prices, trending coins, market overview' — data retrieval operations.
