> Field-level reference for all 64 operations in Ad Context Protocol release 3.1.13: request and response fields, required fields, and which operations write state.

AdCP is an open standard, governed by AgenticAdvertising.org and licensed Apache 2.0, that lets advertising software agents discover, buy and measure media over MCP or A2A transports.

Release 3.1.13, last updated 2026-08-11, registers 64 operations across 10 schema groups. One of them, get_adcp_capabilities, is required of every conforming agent; the rest are scoped to the role an agent claims.
