Use when building an AdCP signals agent — a marketplace data provider, identity provider, CDP, or any system that serves audience or contextual signals to buyers.
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 Signals Agent A signals agent serves audience and contextual targeting segments to buyer agents. The fastest path to a passing agent is to **fork the worked adapter** and replace its `// SWAP:` markers with calls to your backend. ## Pick your fork target | Specialism | Archetype | Fork this | Mock upstream | Storyboard | | -------------------- | ------------------------------------------------------------------------------- | ---------------------------------------------------------------------------------------------------- | ----------------------------------------- | -------------------- | | `signal-marketplace` | Multi-provider data marketplace (Oracle Data Cloud, LiveRamp, third-party data) | [`hello_signals_adapter_marketplace.ts`](../../examples/hello_signals_adapter_marketplace.ts) | `npx adcp mock-server signal-marketplace` | `signal_marketplace` | …

How to install
mdr add adcontextprotocol/adcp-client/build-signals-agent@sha256:0f053ae531215493The line at the top of this page pins the label git:20260508.8117e93, 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.
