D-ID, Descript, Flixly, Higgsfield, Krea, MiniMax, Replicate, Revid, Runway, Synthesia and Vidu also document “an MCP connection”, which makes 12 tools with this reading.
It reflects the documentation on the reading day.
2Why it matters in a pipeline
Agent hooks move generation into the same place as the rest of a technical workflow. A coding agent that can call a video model can also name files, log settings and hand results on without a person in between.
