AI agents use createManyFavorites to create or update resources in Twenty MCP Server — usually the action step of a workflow, after the agent has gathered context. Every call changes real data in your Twenty MCP Server environment.
This tool creates new favorite records, which is a reversible write operation. It modifies CRM data by adding favorites but does not execute arbitrary code, delete data, or move money. The blast radius is limited to non-critical metadata (favorite markers).

From the tool's definition Tool name 'createManyFavorites' and description 'Create Many favorites' indicate batch creation of favorite records in the CRM system.
