What findOneBlocklist does on Twenty MCP Server
AI agents call findOneBlocklist 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 findOneBlocklist is rated Low
This tool retrieves a single blocklist record from the CRM system. It performs a read-only query operation with no side effects—no data is created, modified, deleted, or executed. The low severity reflects minimal risk; an AI agent querying blocklist data poses no significant harm to the system or business operations.
From the tool's definition Tool name "findOneBlocklist" and description "can be provided to request your **blocklist**" indicate a retrieval operation. The verb "find" and the phrase "request your blocklist" clearly denote querying/fetching data without modification.
