On 2026-10-25 the server answered initialize and tools/list without a sign-in. First answer in 224 ms.

• Its tools do every use case we checked: turn a story idea or script into episodes; generate consistent characters and locations for a video series.
• Checked on 2 of the 7 days it takes to judge reliability.

Said by rules from the measurements above. The likely first call is a model's pick from the tool list; read its description before relying on it.

A program checks the server once a day: initialize and tools/list, no model. Tokens are the definitions' length at about four characters a token. The grade averages six checks of every tool's name, description, schema and annotations; it says how well the tools are described, not whether they work. The score weighs what was measured and nothing else: answering (25%), doing the product's job (25%), definitions (20%), context (10%), use (10%) and how readily a client connects (10%). A part that was not measured is left out, and a hidden instruction caps the score at 40. The state of vendors' MCP servers: method and numbers →

• list_project_jobs

  List generation jobs for a project, newest first.

• list_shot_continuity_references

  List the continuity reference images attached to one shot. get_scene_assets also returns these, but only for a whole scene — use this when you need the asset ids, for example to remove one or update its guidance. Each reference's saved…

• generate_script

  Write a full multi-episode script from a story premise. This CREATES A NEW PROJECT — it does not edit an existing one, and it takes no project_id. While the job runs, job.output carries live progress (phase, completedEpisodes…

• generate_shot_clip

  Generate a video clip for a single shot (episode_shots row). Spends credits. Returns a job id — poll it with get_job.

• generate_character_image

  Generate a reference image for a character. Spends credits. Returns a job id — poll it with get_job.

• generate_location_image

  Generate a reference image for a location. Spends credits. Returns a job id — poll it with get_job.

• generate_shot_background_image

  Generate an empty background plate for one short shot. Both reference inputs steer what the plate itself looks like — layout, prop identity, materials and lighting — and are unrelated to upload_shot_continuity_reference, which guides clip…

• generate_episode_music

  Generate a background music track for an episode. Requires the episode to already have an assembled video. Spends credits. Returns a job id — poll it with get_job.

• update_shot

  Overwrite fields on one shot. Read the shot first (get_episode_shots or get_episode_editor), decide the change yourself, then send ONLY the fields you changed — omitted fields are left untouched. To change dialogue, edit…

• update_location

  Overwrite fields on one location. Read it first (get_project_locations or get_location), then send ONLY the fields you changed — omitted fields are left untouched. IMPORTANT: a location is usually shared by several scenes across episodes…

• upload_shot_continuity_reference

  Attach an image you produced locally to a shot as a continuity reference. A continuity reference is fed into this shot's next clip generation as a layout, prop, wardrobe and screen-direction guide — it is NOT used as the shot's opening…

• attach_shot_continuity_reference

  Attach an image that already exists in this project to a shot as a continuity reference. A continuity reference is fed into this shot's next clip generation as a layout, prop, wardrobe and screen-direction guide — it is NOT used as the…

• update_shot_continuity_reference

  Set or clear the guidance on one continuity reference already attached to a shot — the note telling the video model how to use that image. List references first with list_shot_continuity_references to get the asset id. Like attaching…

• remove_shot_continuity_reference

  Detach one continuity reference from a shot. List them first with list_shot_continuity_references to get the asset id. This deletes the reference asset permanently and cannot be undone.
