Runway Brand Kits in MCP: Saved Brand Context and Per-Generation References

What changed in Runway#

Runway's September 22, 2026 changelog says MCP agents can find Brand Kits and use their assets. It explicitly describes MCP access as read-only, with creation and editing remaining in the product. The entry is labeled All Plans. Runway changelog

The Agent help page, reviewed on October 17, still labels its Brand Kit feature Enterprise. It describes applying kits across a chat session and creating or updating them in Agent. These labels should not be merged into a blanket entitlement claim: confirm access to the particular MCP or in-product operation in your own plan before making it part of a production process.

Runway's help also distinguishes attached references from kit guidance and cautions that brand intent does not guarantee an outcome. That is a useful operational distinction: storing an approved logo and receiving an accurate logo in every generated frame are different achievements.

Organize the material by what it establishes#

Consider a small bicycle accessory brand preparing a series around one reflective handlebar bag. The material may include product photographs, a logo, a color palette, an illustration of a recurring cyclist, and examples of evening street lighting.

Do not place all of those materials into one undifferentiated instruction. A product photograph establishes construction. A logo establishes a precise mark. A character image establishes recognizable appearance. A lighting reference establishes an atmosphere. The palette may influence the scene without authorizing a change to the product's real color.

Create a short description for each group in your own material packet. Explain the details that carry identity and the details that can vary. “Keep the bag's rectangular opening, two attachment straps, and reflective front strip” is more useful than “make it on-brand.”

This preparation works whether you later place the material in a supported saved kit or provide selected references directly for a scene. It improves the brief without depending on a particular storage mechanism.

Separate durable rules from scene instructions#

Durable guidance describes the things that should remain true across the series: the product's construction, the character's recognizable features, and the preferred visual tone. Scene instructions describe what happens today: the cyclist locking a bicycle, opening the bag, or arriving at a café.

For the reflective bag, a durable rule might be that the reflective strip remains on the front panel. A scene instruction might ask for the cyclist to stand beside a parked bicycle under a streetlight. If you mix them, a dramatic lighting reference can accidentally become a request to redesign the bag.

Use this division when reviewing a result. If the strip changes position, the output fails a durable product condition. If the cyclist looks in an unhelpful direction, the problem is the current scene. The distinction helps you request a focused correction rather than rewriting the entire identity description.

Resolve contradictions before generation#

A reusable set of references can preserve confusion as efficiently as it preserves a decision. If one product photograph shows an old strap and another shows the current design, explain which version controls. If a character reference shows two different hairstyles, choose the intended identity for the current project.

Review the packet whenever a real product or campaign requirement changes. Keep old and current materials distinguishable in your own records. A creator should be able to tell whether an older image is an approved source, a visual inspiration, or a superseded design.

When a scene requires an exception, state it explicitly. A winter edition may use a new product color while retaining the construction. A dream sequence may use different lighting while preserving the character. Exceptions work best when the unchanged elements are just as clear as the new ones.

Use scene references with a narrow purpose#

Once the durable brief is coherent, add only the references needed for the current shot. An environment reference can explain the street layout. A movement reference can explain how the cyclist reaches into the bag. Neither should silently replace the approved product design.

An illustrative scene brief might read:

Use the product photographs for the bag's construction and color. Use the cyclist reference for appearance. The evening street image guides the lighting only. The cyclist stops beside the bicycle and opens the bag with one hand. Keep the reflective strip visible on the front panel.

This prompt is a teaching example, not an observed generation. Its useful feature is the allocation of authority. When a result drifts, you can identify which input's role was unclear.

Avoid filling a shot with every available brand asset. A logo, character, product, patterned background, slogan, and dramatic camera move may compete for attention. Decide what the viewer needs to recognize first and give it enough visual space.

Review the result at three levels#

First, review identity. Compare the product silhouette, straps, reflective strip, and character features with the approved sources. Look beyond the opening frame; a detail may drift during movement.

Second, review scene meaning. The cyclist's action should be understandable, the bag should remain the intended subject, and the environment should support the story. An output can contain the correct ingredients while communicating the wrong use of the product.

Third, review exact information. Logos, packaging words, claims, and prices deserve a separate check. Where exact text is required, use an approach that lets you control and inspect it directly instead of assuming generated lettering is reliable.

Keep a short acceptance note for each result: what was retained, what changed, and what still needs attention. This is a suggested review habit, not a claim that a platform automatically saves an approval history.

Where MyloStudio fits in the process#

MyloStudio is useful when you want to turn your brand materials into images and videos, inspect the result, and ask for a targeted revision. Its multiple-reference and source-understanding capabilities help organize a creative request; its editing and variation capabilities support continued work after the first result.

For the bag example, start by establishing the product in one clear scene. Revise an inaccurate construction detail before creating a sequence around it. Then develop different situations while keeping the approved identity brief available to the people doing the work.

Use Runway's documented Brand Kit mechanisms when their saved-context and MCP access fit your workflow and account. Use MyloStudio when your immediate goal is to develop, animate, and revise your own materials. In either route, clear source responsibilities and visible acceptance criteria make consistency something you can inspect rather than merely request.
