call-adcp-agent SKILL.md skillA
call-adcp-agent from adcontextprotocol/adcp-client is an agent skill: a SKILL.md folder an AI agent loads when a task calls for it.
mdr add adcontextprotocol/adcp-client/call-adcp-agent@git:20261019.1159cd0Pins git:20261019.1159cd0 in mdr.lock. Pin the fingerprint instead.

Wire-level invariants for any AdCP buyer call — idempotency_key replay semantics, account `oneOf` variants, async `status:'submitted'`+`task_id` polling, error recovery from `adcp_error.issues[]`. Load before any per-protocol task skill (adcp-media-buy, adcp-creative, adcp-signals, adcp-governance, adcp-si, adcp-brand) when calling an AdCP agent as a buyer.
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
# Call an AdCP agent ## Overview AdCP (Ad Context Protocol) agents expose a fixed tool surface over MCP or A2A. For media buying, prefer the AdCP 3.2 lifecycle: `list_products` → `buy_products` → `control_media_buy`, or `request_proposals` → `refine_proposals` → `accept_proposal`. The established `get_products` / `create_media_buy` / `update_media_buy` surface remains for 3.0/3.1 compatibility. Tool names come from `get_adcp_capabilities`; exact request/response shapes come from `get_schema(tool_name)` when available or from the bundled JSON Schemas. This skill teaches the invariants that don't live cleanly in any schema: cross-tool patterns, async flow, error recovery. ## When to Use - User wants to call a publisher / SSP / retail media network over AdCP - Tool names like `list_products`, `buy_products`, `request_proposals`, `sync_creatives`, or `get_signals` appear in the available-tools list - Agent card advertises `protocolVersion: '0.3.0'` with `skills` listing AdCP tool names - **Not this skill:** building an AdCP seller agent (see `@adcp/client/skills/build-seller-agent/` and analogous SDK skills) ## Discovery chain Walk these in order on first contact: …

How to install
mdr add adcontextprotocol/adcp-client/call-adcp-agent@sha256:0e90451669023b68The line at the top of this page pins the label git:20261019.1159cd0, 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.
