Verifies the configured eToro API key works and lists any agent-portfolios on the account (read-only).
AI agents call etoro_check_connection to retrieve information from eToro MCP Server without modifying anything — typically the context-gathering step in research, monitoring, and reporting workflows, before the agent takes action elsewhere.
This tool performs a connection health check and retrieves portfolio listing metadata. No state changes, no financial transactions, and no command execution occurs. The read-only designation and listing behavior fit the Read category definition. Severity is low because the information returned (API validity and portfolio names) poses minimal risk even if exposed to a malicious agent.
From the tool's definition Description explicitly states 'read-only' and 'verifies... and lists', indicating data retrieval with no modifications or side effects.
