get_all_assets
AI agents call get_all_assets to retrieve information from Alpaca MCP Server without modifying anything — typically the context-gathering step in research, monitoring, and reporting workflows, before the agent takes action elsewhere.
This tool retrieves asset information from Alpaca's trading infrastructure. It performs a read-only query operation that returns data about available assets (stocks, options, crypto) without modifying, deleting, or executing any trades. The absence of description lowers confidence slightly, but the consistent 'get_' naming pattern and sibling tool context strongly indicate a Read category classification.
From the tool's definition Tool name 'get_all_assets' combined with server context showing sibling tools like 'get_account_info' and 'get_asset_info' indicates a retrieval operation.
