QuestionQ36

Tool Design & MCP Integration

An MCP server provides archive_file(file_id) and delete_file(file_id) tools. Production logs indicate that the agent invokes delete_file when users request to “remove old backups,” yet company policy requires backup files to be archived. Both tools presently have minimal descriptions: “Archives a file” and “Deletes a file.” Which change most directly improves tool selection in this scenario?

Explanation

Tool descriptions are presented to the model as human-readable guidance and can serve as hints that improve its understanding of each available tool. Explicitly stating that delete_file must not be used for backup files distinguishes the tools at the point of selection, directing backup-related requests to archive_file.
