AdCP — get

Task: Discover signals based on description, with details about where they are deployed. Response Time: ~60 seconds (inference/RAG with back-end systems) Request Schema: https://adcontextprotocol.org/schemas/v3/signals/get-signals-request.json Response Schema: https://adcontextprotocol.org/schemas/v3/signals/get-signals-response.json The get_signals task returns both signal metadata and real-time deployment status across platforms, allowing agents to understand availability and guide the activation process.

Request Parameters

Parameter	Type	Required	Description
`signal_spec`	string	Conditional	Natural language description of the desired signals. Required unless `signal_ids` is provided.
`signal_ids`	SignalID[]	Conditional	Specific signals to look up by data provider and ID. Required unless `signal_spec` is provided.
`account`	AccountRef	No	Account for this request. When provided, the signals agent returns per-account pricing options if configured.
`destinations`	Destination[]	No	Filter signals to those activatable on specific agents/platforms. When omitted, returns all signals available on the current agent. See Destination Object below.
`countries`	string[]	No	Countries where signals will be used (ISO 3166-1 alpha-2 codes)
`filters`	Filters	No	Filters to refine results (see Filters Object below)
`max_results`	number	No	Deprecated. Use `pagination.max_results` instead. When both are present, `pagination.max_results` takes precedence. Will be removed in AdCP 4.0.
`pagination`	object	No	Pagination envelope. `pagination.max_results` (max: 100, default: 50) controls page size; `pagination.cursor` (opaque token from previous response) advances pages.

Destination Object

Each deployment target uses a type field to discriminate between platform-based and agent-based deployments:

Parameter	Type	Required	Description
`type`	string	Yes	Discriminator: “platform” for DSPs, “agent” for sales agents
`platform`	string	Conditional*	Platform identifier (e.g., ‘the-trade-desk’, ‘amazon-dsp’). Required when type=“platform”
`agent_url`	string (URI)	Conditional*	URL identifying the sales agent. Required when type=“agent”
`account`	string	No	Account identifier on the platform or agent

*platform is required when type="platform", agent_url is required when type="agent". Destination filtering: Signals are returned if they are available on any of the requested destinations (OR semantics). Destinations where a signal is not available are omitted from that signal’s response deployments array. A PARTIAL_COVERAGE warning may be included when some destinations don’t support the signal. Activation Keys: If the authenticated caller has access to any of the destinations in the request, the signal agent will include activation_key fields in the response for those deployments (when is_live: true). Permission Model: The signal agent determines key inclusion based on the caller’s authentication and authorization. For example:

A sales agent receives keys for deployments matching its agent_url
A buyer with credentials for multiple DSP platforms receives keys for all those deployments
Access is determined by the signal agent’s permission system, not by flags in the request

Filters Object

Parameter	Type	Required	Description
`catalog_types`	string[]	No	Filter by catalog type (“marketplace”, “custom”, “owned”)
`data_providers`	string[]	No	Filter by specific data providers
`max_cpm`	number	No	Maximum CPM price filter. Excludes signals where all CPM-based pricing options exceed this value. Signals without CPM-based pricing options are not affected by this filter.
`min_coverage_percentage`	number	No	Minimum coverage requirement

Response Structure

All AdCP responses include:

message: Human-readable summary of the operation result
context_id: Session continuity identifier for follow-up requests
data: Task-specific payload (see Response Data below)

The response structure is identical across protocols, with only the transport wrapper differing:

MCP: Returns complete response as flat JSON
A2A: Returns as artifacts with message in text part, data in data part

Field Descriptions

signals: Array of matching signals
- signal_agent_segment_id: Unique identifier for the signal
- name: Human-readable signal name
- description: Detailed signal description
- signal_type: Type of signal. One of:
  - marketplace — resold third-party segment (provider authorization verifiable via the provider’s adagents.json)
  - owned — first-party segment derived from data the signal agent directly owns
  - custom — agent-native segment built on demand from models, composites, or buyer inputs (not attributable to a standing upstream provider)
- data_provider: Name of the data provider
- coverage_percentage: Percentage of audience coverage
- deployments: Array of destination deployments
  - agent_url: URL identifying the destination agent
  - account: Account identifier if applicable
  - is_live: Whether signal is currently active on this deployment
  - activation_key: The key to use for targeting (see Activation Key below). Only present when is_live=true and the authenticated caller has access to this deployment.
  - estimated_activation_duration_minutes: Time to activate if not live
- pricing_options: Array of pricing options for this signal. Pass the selected pricing_option_id in report_usage for billing verification.
  - pricing_option_id: Unique identifier for this pricing option
  - model: Pricing model — cpm, percent_of_media, flat_fee, per_unit, or custom
  - model: "cpm" — cpm (number, cost per thousand impressions), currency (ISO 4217)
  - model: "percent_of_media" — percent (0–100), currency (ISO 4217), max_cpm (optional CPM cap: effective charge = min(percent × media_spend_per_mille, max_cpm))
  - model: "flat_fee" — amount (fixed charge), currency (ISO 4217), period (monthly, quarterly, annual, or campaign)
  - model: "per_unit" — unit (what is counted), unit_price (cost per one unit), currency (ISO 4217)
  - model: "custom" — description (human-readable), metadata (structured parameters), currency (optional). Escape hatch for performance kickers, tiered volume, hybrid formulas, or any construct the standard models cannot express. Buyers SHOULD route custom pricing through operator review before commitment.

Select the pricing option that matches your billing model and pass its pricing_option_id in report_usage for billing verification. If a signal offers multiple models (e.g., CPM and flat fee), choose based on your expected delivery volume and campaign structure.

Activation Key Object

The activation key represents how to use the signal on a deployment target. It can be either a segment ID or a key-value pair: Segment ID format:

{
  "type": "segment_id",
  "segment_id": "ttd_segment_12345"
}

Key-Value format:

{
  "type": "key_value",
  "key": "audience_segment",
  "value": "luxury_auto_intenders"
}

Protocol-Specific Examples

The AdCP payload is identical across protocols. Only the request/response wrapper differs.

MCP Request - Sales Agent Requesting Signals

Error Codes

Discovery Errors

REFERENCE_NOT_FOUND: Referenced signal_agent_segment_id doesn’t exist, OR a private signal agent is not visible to this account. The same code is returned whether the resource exists but is unauthorized or truly does not exist — sellers MUST NOT distinguish the two (see error.field to identify which typed parameter failed to resolve). See the uniform-response MUST in error-handling.mdx.
AGENT_ACCESS_DENIED: Authenticated agent’s credentials did not authorize access to this signal agent

Discovery Warnings

PRICING_UNAVAILABLE: Pricing data temporarily unavailable for one or more platforms
PARTIAL_COVERAGE: Some requested platforms don’t support this signal type
STALE_DATA: Some signal metadata may be outdated due to provider refresh delays

Usage Notes

Authentication-Based Keys: Activation keys are only returned when the authenticated caller matches one of the deployment targets
Permission Security: The signal agent determines key inclusion based on caller identity, not request flags
Deployment Status: Check is_live to determine if activation is needed
Multiple Deployments: Query multiple deployment targets to check availability across platforms
Activation Required: If is_live is false, use the activate_signal task
The message field provides a quick summary of the most relevant findings

get_signals supports iterative refinement without a separate mode flag. The combination of signal_spec and signal_ids determines the operation:

Fields provided	Behavior
`signal_spec` only	Discovery — find signals matching the description
`signal_ids` only	Exact lookup — return specific signals by ID
`signal_ids` + `signal_spec`	Refinement — start from known signals, adjust per the spec

To refine previous results, pass back the signal_id values from signals you want to keep, and provide an updated signal_spec describing what to change:

{
  "$schema": "/schemas/signals/get-signals-request.json",
  "signal_spec": "Same audience but with broader coverage, ideally above 20%",
  "signal_ids": [
    {
      "source": "catalog",
      "data_provider_domain": "experian.com",
      "id": "luxury_auto_intenders"
    }
  ],
  "destinations": [
    {
      "type": "agent",
      "agent_url": "https://wonderstruck.salesagents.com"
    }
  ],
  "countries": ["US"]
}

The signal agent uses the provided IDs as a starting point and the spec as adjustment guidance, returning signals that reflect both the original selection and the requested changes (e.g., broader segments from the same provider, or comparable segments from alternative providers with higher coverage).
