Use when building an AdCP generative seller — an AI ad network, generative DSP, or platform that sells inventory AND generates creatives from briefs.
Collected from public GitHub. Every version is saved exactly as it was and never changes. Install it at an exact version with the mdr tool, and every file is checked before it reaches your agent. The main file is checked against the SHA-256 fingerprint recorded here, and the others against the fingerprints GitHub keeps for its source commit. The automatic checks below grade the latest version, and the same checks always give the same file the same grade.
What the file says
# Build a Generative Seller Agent A generative seller does everything a standard seller does (products, media buys, delivery) **plus** generates creatives from briefs. The buyer sends a creative brief instead of uploading pre-built assets. Your platform resolves the brand identity, generates the creative, and serves it. A generative seller that sells programmatic inventory MUST also accept standard IAB formats (display images, VAST tags, HTML banners). The generative capability is additive — buyers who already have creatives need to upload them directly. ## Pick your fork target There's no dedicated `hello_generative_seller_adapter_*.ts` yet — generative-seller is `sales-non-guaranteed` + `creative-generative`, so adopters fork the seller adapter and add the `build_creative` surface. | Specialism | Status | Fork this | Add | Storyboard | | --- | --- | --- | --- | --- | | `creative-generative` | stable | [`hello_seller_adapter_non_guaranteed.ts`](../../examples/hello_seller_adapter_non_guaranteed.ts) | `creatives.buildCreative`, `creatives.previewCreative`, brand-resolution logic | `creative_generative` | …

How to install
mdr add adcontextprotocol/adcp-client/build-generative-seller-agent@sha256:56177e7cb7118ac0The line at the top of this page pins the label git:20260503.5118d4a, which is what most people want. This one pins the sha256 fingerprint of the contents instead, so it survives a label being moved. Either way the exact version is written to mdr.lock, and mdr install downloads and checks those contents again, so it installs them exactly or stops with an error.
