WHAT IT DOES

What crypto.cex-ticker does on Mcp

AI agents call crypto.cex-ticker to retrieve information from Mcp without modifying anything. It is typically the context-gathering step in research, monitoring, and reporting workflows, before the agent takes action elsewhere.

RISK

Why crypto.cex-ticker is rated Low

This is a data-retrieval tool that queries real-time market pricing information. No write, execute, destructive, or financial operations occur — the tool only reads and returns ticker data. The severity is low because misuse carries minimal risk (returning stale or incorrect price quotes has limited blast radius compared to trade execution or fund transfers).

From the tool's definition Tool retrieves 'current price, best bid/ask, 24h open/high/low, 24h + 30d volume, and 24h percent change' — purely informational queries with no side effects.
