AdCP — Schemas and SDKs

Get started integrating with AdCP using our schemas and official SDKs.

Schema Access

AdCP schemas are available from two sources:

Source	URL	Best For
Website	`https://adcontextprotocol.org/schemas/v2/`	Runtime fetching, version aliases
GitHub	`https://github.com/adcontextprotocol/adcp/tree/main/dist/schemas`	Offline access, CI/CD pipelines

Both sources contain identical schemas. The GitHub repository includes all released versions with bundled schemas committed directly to the codebase.

Common Schemas

Schema	URL
Product	`https://adcontextprotocol.org/schemas/v2/core/product.json`
Media Buy	`https://adcontextprotocol.org/schemas/v2/core/media-buy.json`
Creative Format	`https://adcontextprotocol.org/schemas/v3/core/format.json`
Schema Registry	`https://adcontextprotocol.org/schemas/v3/index.json`

For AI Coding Agents

Point your AI coding agent to https://docs.adcontextprotocol.org/mcp for MCP integration documentation.

Client SDKs

AdCP provides official SDKs for JavaScript/TypeScript and Python. These work for both client and server implementations.

JavaScript / TypeScript

npm install @adcp/client

import { ADCPClient } from '@adcp/client';

const client = new ADCPClient({
  agentUrl: 'https://sales.example.com'
});

const products = await client.getProducts({
  brief: 'Video campaign for pet owners'
});

Resources:

Package exports:

@adcp/client — Main API
@adcp/client/testing — Testing utilities (includes testAgent)
@adcp/client/advanced — Advanced API features
@adcp/client/types — TypeScript type definitions

Python

pip install adcp

from adcp import ADCPClient

client = ADCPClient(agent_url='https://sales.example.com')

products = client.get_products(
    brief='Video campaign for pet owners'
)

Resources:

CLI Tools

Both SDKs include command-line tools for testing and development.

JavaScript CLI

npx @adcp/client --help
npx @adcp/client get-products --agent https://sales.example.com --brief "CTV campaign"

Python CLI

uvx adcp --help
uvx adcp get-products --agent https://sales.example.com --brief "CTV campaign"

Schema Versioning

AdCP uses semantic versioning. Choose the right path for your use case:

Path	Example	Best For
Exact version	`/schemas/2.5.3/`	Production, SDK generation
Major version	`/schemas/v2/`	Development, documentation
Minor version	`/schemas/v2.5/`	Stable development (patch updates only)

Production (Recommended)

Pin to an exact version for stability:

const SCHEMA_VERSION = '2.5.3';
const schema = await fetch(
  `https://adcontextprotocol.org/schemas/${SCHEMA_VERSION}/core/product.json`
);

Development

Use the major version alias to stay current with backward-compatible updates:

const schema = await fetch(
  'https://adcontextprotocol.org/schemas/v2/core/product.json'
);

SDK Type Generation

# TypeScript
npx json-schema-to-typescript \
  https://adcontextprotocol.org/schemas/2.5.3/core/product.json \
  --output types/product.d.ts

# Python
datamodel-codegen \
  --url https://adcontextprotocol.org/schemas/2.5.3/core/product.json \
  --output models/product.py

Bundled Schemas

For tools that don’t support $ref resolution, use bundled schemas with all references resolved inline. Bundled schemas are available from both the website and GitHub:

Website Access

https://adcontextprotocol.org/schemas/2.5.3/bundled/media-buy/create-media-buy-request.json

GitHub Access

Bundled schemas are committed to the repository at dist/schemas/{VERSION}/bundled/:

# Clone and access locally
git clone https://github.com/adcontextprotocol/adcp.git
ls adcp/dist/schemas/2.5.3/bundled/media-buy/

# Or fetch directly via GitHub raw
curl https://raw.githubusercontent.com/adcontextprotocol/adcp/main/dist/schemas/2.5.3/bundled/media-buy/get-products-request.json

Version Discovery

# Get current version
curl https://adcontextprotocol.org/schemas/v2/index.json | jq '.adcp_version'

Check Release Notes for version history and migration guides.

Registry API

The AgenticAdvertising.org registry provides a public REST API for brand resolution, property resolution, agent discovery, and authorization validation. No authentication required.

Registry API Reference
