AI agents call get_notes to retrieve information from Kommo CRM 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 notes associated with leads, contacts, or companies in the CRM system. It performs a read-only query operation with no side effects, no data modification, and no irreversible actions. The blast radius of misuse is minimal—an agent could retrieve notes it shouldn't access, but no data would be deleted, modified, or financial actions taken.
From the tool's definition Tool name is 'get_notes' and description states 'Obter notas de um lead, contato ou empresa' (Get notes from a lead, contact or company). The verb 'get' and 'obter' (obtain) indicate data retrieval without modification.
