MCP tool reference - ElarisLabs

Discovery tools are free. Generation and editing tools consume credits from the key’s brand. Scheduler tools queue posts without consuming generation credits.

Model tip: pass model: "auto" (the default) to let the router pick. Or pass a specific id from list_models, such as "flux-2-flash" for fast images.

Scheduler

All tools in this group are free — they never consume credits. Use them to confirm connectivity, inspect your brand, and plan generation calls.

Tool	What it does	Key parameters
`list_brands`	Brand this key is bound to	none
`list_workspaces`	Workspace for this key	none
`list_projects`	Creative Studio projects	none
`get_project`	Single project plus flow graph	`projectId`
`list_models`	Image, video, audio models	`kind` (optional filter)
`list_templates`	Published Studio templates	none

`brand_pack_list_sizes`	Available brand-pack output sizes	none
`list_scheduler_integrations`	Connected publish accounts	none
`list_scheduled_posts`	Queued and published posts	none

These tools consume credits from the brand balance associated with the key. Call get_credits first to confirm available balance.

Tool	What it does	Key parameters
`generate_image`	Text-to-image or edit with references	`prompt`, `model`, `referenceImages`, `resolution`
`generate_video`	Text-to-video or image-to-video	`prompt`, `imageUrl`, `durationSeconds`
`regenerate_video`	Re-run video with optional variation	`prompt`, `variationHint`
`generate_audio`	Text-to-speech (ElevenLabs, Gemini)	`text`, `model`, `voice`, `language`
`create_hyperlapse`	Stitch images into a timelapse	`images[]`, `fps`, `width`, `height`
`composer_edit`	add_text, inpaint, erase, remove_background	`operation`, `imageUrl`

`brand_pack_resize`	Resize into sizes, returns a zip	`sourceImage`, `sizeKeys`

Video and brand-pack tools may take 30–90 seconds. If your MCP client has a short tool timeout, retry or request a shorter durationSeconds for video.

Scheduler tools queue posts to connected social accounts. No generation credits are consumed — only the scheduling action itself.

Tool	What it does	Notes
`schedule_post`	Queue a post to a connected account	Requires `list_scheduler_integrations` to confirm connected accounts first

Call list_scheduler_integrations before schedule_post to confirm the target platform is connected and get the correct integration ID.
