Runway MCP | Brand Kits become references for connected agents
Runway MCP now lets connected agents find Brand Kits and use their assets as references. The September 22 update is listed for all plans, with access through MCP remaining read-only. Kit creation and editing continue inside Runway, giving the connection a defined role in an AI creative workflow.
Brand references can travel into an agent workflow
For designers, the useful change is access to an established reference collection from an agent session. It could support a brief that depends on specific visual material, such as a campaign direction or product identity. The quality of that starting point will still depend on what the team puts into the kit.
A reference collection should answer practical questions before generation begins. Which image represents the current product? Which treatment expresses the intended mood? Which elements should remain recognizable? Making those decisions explicit can help a team avoid spending its first review explaining why an output followed an outdated or unsuitable example.
Prepare the kit around actual creative decisions
Consider organizing a kit around one production purpose before attempting to cover an entire brand. A launch campaign might need a narrower visual direction than an evergreen content library. Keeping that distinction clear can make it easier for a creator to explain why one set of references is appropriate for the current brief.
Text instructions should describe how the references are meant to influence the result. A palette reference, a composition example, and a product photograph serve different purposes. Asking for a visual that simply looks like the kit leaves important decisions open, including which features are essential and which are only suggestions.
Read access keeps kit maintenance in Runway
Read-only access separates reference use from reference maintenance. That boundary matters when several people depend on the same collection: generating from a kit and changing its contents are different responsibilities. A team should agree who keeps the source collection current before relying on it for repeated creative requests.
When a campaign direction changes, review the kit in Runway before producing another batch. It is also sensible to record which references were intended for a particular brief. This gives reviewers a concrete basis for assessing the result, rather than relying on memory of a visual direction discussed earlier.
Test consistency with a small campaign brief
A useful pilot could ask for several interpretations of one approved concept. Compare the treatment of recognizable product details, background mood, and visual emphasis. Treat these as evaluation criteria chosen by the team, rather than assumed guarantees from the connection. Reference access alone does not establish that every generated result is brand-ready.
Keep the first review small enough to explain each rejection. If a variation misses the brief, identify whether the source material was ambiguous or the instructions left room for the wrong interpretation. That distinction can guide the next change and reduce the temptation to generate more options without improving the creative setup.
IMPORTANT: Brand Kits are read-only through Runway MCP. Create and edit them in Runway itself.{alertWarning}
Daisuki's Take: What This Means for Designers
We think this update is most valuable for teams that already have a deliberate reference system. Making that system available to an agent could help preserve the thinking behind a brief as work moves into another interface.
We would give kit preparation the same attention as prompt writing. A carefully written request cannot compensate for a collection that mixes unrelated campaigns, superseded assets, and examples with no explanation of their intended use.
Start with a single campaign and a clearly owned kit. Judge whether the team reaches acceptable variations with fewer clarification rounds. That is a more useful outcome than simply having brand references available in another place.
