What findOneViewField does on Twenty MCP Server
AI agents call findOneViewField to retrieve information from Twenty MCP Server without modifying anything. It is typically the context-gathering step in research, monitoring, and reporting workflows, before the agent takes action elsewhere.
Why findOneViewField is rated Low
The tool retrieves a view field definition with optional depth parameter for nested data. This is a read-only query operation with no side effects. Severity is low as it only accesses CRM metadata/configuration, not sensitive business data directly, and has minimal blast radius if misused.
From the tool's definition Tool name 'findOneViewField' uses the 'find' verb, indicating a retrieval operation. Description mentions 'request your viewField', suggesting it queries or fetches a specific field configuration without modifying data.
