Call an AdCP agent

Overview

AdCP (Ad Context Protocol) agents expose a fixed tool surface (get_products, create_media_buy, get_signals, …) over MCP or A2A. Tool names come from get_adcp_capabilities; exact request/response shapes come from get_schema(tool_name) when the agent exposes it, otherwise from the bundled JSON Schemas your SDK ships (the layout differs by SDK — see "Discovery chain" below). 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 get_products, create_media_buy, sync_creatives, 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)
