Execute AdCP Sponsored Intelligence (SI) Protocol operations with brand agents - start conversational sessions, send messages, preview offerings, and manage session lifecycle. Use when users want to have conversations with brand agents, explore product offerings, or manage sponsored interactions.
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
# AdCP Sponsored Intelligence (SI) Protocol This skill enables you to execute the AdCP SI Protocol with brand agents. SI enables conversational commerce sessions where users engage directly with brand agents for shopping, inquiries, and transactions. > **Buyer-side basics** — idempotency replay, `oneOf` variants, async `status:'submitted'` polling, error recovery from `adcp_error.issues[]` — live in `skills/call-adcp-agent/SKILL.md`. This skill covers per-task semantics only. ## Overview The SI Protocol provides 4 standardized tasks for managing conversational sessions: | Task | Purpose | Response Time | |------|---------|---------------| | `si_initiate_session` | Start a brand conversation | ~2-5s | | `si_send_message` | Send a message in an active session | ~1-5s | | `si_get_offering` | Preview offerings before starting | ~1-3s | | `si_terminate_session` | End a session | ~1s | ## Typical Workflow 1. **Preview** (optional): `si_get_offering` to see what the brand offers before consent 2. **Start session**: `si_initiate_session` with the user's `intent` and consent 3. **Converse**: `si_send_message` to relay user messages and action responses …

How to install
mdr add adcontextprotocol/adcp-client/adcp-si@sha256:511ba1eeeb719dceThe line at the top of this page pins the label git:20260430.6c25e2d, 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.
