Segments

A segment is a saved audience: one row per record of a root cube, kept when it matches a filter. It's defined over the semantic model (cubes), not over a table — tables only borrow a segment to scope their rows.

You reach it through the RevOS MCP server's generic tools on the segments resource: api_read lists and gets, api_write creates (no id) and updates (with id). api_details({ resource: "segments", operation: "create" }) is the authority on the body shape; this skill covers what that schema can't tell you.
