Indica cuántos documentos hay en una colección
AI agents call contar_documentos to retrieve information from Modular 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 read-only query operation against MongoDB to return a document count. It has no side effects, does not modify data, and is purely informational. The low severity reflects minimal blast radius if misused—an agent could only learn collection sizes, not access sensitive data or cause harm.
From the tool's definition Tool name 'contar_documentos' (count documents) and description 'Indica cuántos documentos hay en una colección' (Indicates how many documents are in a collection) indicate a query operation that retrieves a count metric without modifying data.
