Adcp Media Buy

AdCP Media Buy Protocol

This skill enables you to execute the AdCP Media Buy Protocol with sales agents. Use the standard MCP tools (get_products, create_media_buy, sync_creatives, etc.) exposed by the connected agent.

Overview

The Media Buy Protocol provides 8 standardized tasks for managing advertising campaigns:

Typical Workflow

1. Discover products: get_products with a natural language brief
2. Review formats: list_creative_formats to understand creative requirements
3. Create campaign: create_media_buy with selected products and budget
4. Upload creatives: sync_creatives to add creative assets
5. Monitor delivery: get_media_buy_delivery to track performance

Key Concepts

Brand identity

Brand context is provided by domain reference:

{
  "brand": {
    "domain": "acmecorp.com"
  }
}

The agent resolves the domain to retrieve the brand's identity (name, colors, guidelines, etc.) from its brand.json file.

Format IDs

Creative format identifiers are structured objects:

{
  "format_id": {
    "agent_url": "https://creative.adcontextprotocol.org",
    "id": "display_300x250"
  }
}

The agent_url specifies which creative agent defines the format. Use https://creative.adcontextprotocol.org for standard IAB formats.

Pricing Options

Products include pricing_options array. Each option has:

• pricing_option_id: Use this in create_media_buy
• pricing_model: "cpm", "cpm-auction", "flat-fee", etc.
• price: Base price (for fixed pricing)
• floor: Minimum bid (for auction)

For auction pricing, include bid_price in your package.

Asynchronous Operations

Operations like create_media_buy and sync_creatives may require human approval. The response includes:

• status: "pending" - Operation awaiting approval
• task_id - For tracking async progress

Poll or use webhooks to check completion status.

Error Handling

Common error patterns:

• 400 Bad Request: Invalid parameters - check required fields
• 401 Unauthorized: Invalid or missing authentication token
• 404 Not Found: Invalid product_id, media_buy_id, or creative_id
• 422 Validation Error: Schema validation failure - check field types

Error responses include:

{
  "errors": [
    {
      "code": "VALIDATION_ERROR",
      "message": "budget must be greater than 0",
      "field": "packages[0].budget"
    }
  ]
}

Testing Mode

For testing without real transactions, agents may support:

• X-Dry-Run: true header - Preview without side effects
• Test products with test: true flag
• Sandbox environments

Ask the agent about testing capabilities before creating real campaigns.
