WHAT IT DOES

What UpdateOneMessageFolder does on Twenty MCP Server

AI agents use UpdateOneMessageFolder 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.

RISK

Why UpdateOneMessageFolder is rated Medium

The tool updates a single message folder entity within the Twenty CRM system. This is a reversible modification operation (Write category), not destructive. Severity is medium because misuse could corrupt user organization (e.g., renaming/moving message folders unintentionally), but the effects are limited to one folder and reversible.

From the tool's definition Tool name 'UpdateOneMessageFolder' indicates a modification operation. The description 'Update One messageFolder' confirms it modifies an existing CRM data entity.
