get_corporate_announcements
AI agents call get_corporate_announcements 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 corporate announcements, which is a read-only operation with no side effects. It does not execute trades, modify positions, delete data, or commit financial obligations. While the server context involves financial infrastructure, this specific tool only fetches publicly available market information.
From the tool's definition Tool name 'get_corporate_announcements' indicates retrieval of announcement data with no modification capability. The empty description limits certainty, but the 'get_' prefix and context within a financial trading server suggest a query operation.
