Get Comment by Identifier task.commentitem.get

If you are developing integrations for Bitrix24 using AI tools (Codex, Claude Code, Cursor), connect to the MCP server so that the assistant can utilize the official REST documentation.

Scope: task

Who can execute the method: any user with read access permission for the task or higher
