Search for API documentation and endpoints from VNDirect, FireAnt, or SSI. Returns information about available APIs, endpoints, and documentation URLs.
AI agents call search_vn_stock_api to retrieve information from VN Stock API 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 and queries existing API documentation and endpoint metadata. It has no side effects, does not execute operations, modify data, or access sensitive market data directly. The blast radius of misuse is minimal — an agent could only retrieve publicly available API documentation that would be accessible through normal channels.
From the tool's definition Tool description states it 'Search for API documentation and endpoints' and 'Returns information about available APIs, endpoints, and documentation URLs' — purely informational retrieval with no modification, deletion, execution, or financial operations.
