get_brand_identity

get_brand_identity is the AdCP task for retrieving brand data from a brand agent. Returns logos, colors, fonts, visual guidelines, tone, and voice synthesis config with public and authorized access tiers.

Retrieve brand identity data from a brand agent. Core identity (house, names, description, logos) is always public — any agent can discover who a brand is without authentication. Linked accounts get deeper data: high-res assets, voice synthesis configs, tone guidelines, and rights availability.

Schema

• Request: get-brand-identity-request.json
• Response: get-brand-identity-response.json

Response time

Typically under 2 seconds for identity data. Authorized responses with large asset collections may take longer.

Public by default

Brand identity is public data. Any agent can call get_brand_identity without a linked account and receive the brand’s core identity: house, names, description, industries, and basic logos. This is the same data available in brand.json — get_brand_identity provides it via MCP for agents that prefer a structured call over fetching and parsing the file.

The registry enforces this: every brand indexed from brand.json is publicly discoverable. You can always find out what house a brand belongs to, what it’s called, and what it does.

Authorized callers (linked via sync_accounts) get deeper data on top of the public baseline.

Account linking is a one-time setup: a buyer agent calls sync_accounts on the brand agent, providing its brand reference. After that, the buyer’s get_brand_identity requests are recognized as authorized.

Level	What you get
Public (no linked account)	House, names, description, industries, keller_type, basic logos, tagline
Authorized (linked via sync_accounts)	Everything above, plus: high-res assets, voice synthesis, tone guidelines, content restrictions, rights availability

If a request includes fields that require authorization the caller does not have, those fields are silently omitted. The response includes available_fields listing what sections exist but were not returned, so the caller knows what they would gain by linking their account.

Quick start

Request (public)

{
  "brand_id": "daan_janssen"
}

Request (authorized, specific fields)

{
  "brand_id": "daan_janssen",
  "fields": ["logos", "tone", "voice_synthesis"],
  "use_case": "endorsement"
}

Request (creative production)

{
  "brand_id": "daan_janssen",
  "fields": ["colors", "fonts", "visual_guidelines"],
  "use_case": "creative_production"
}

Response (error)

{
  "errors": [
    { "code": "brand_not_found", "message": "No brand with id 'unknown_brand' in this agent's roster" }
  ]
}

Parameters

Request

Field	Type	Required	Description
brand_id	string	Yes	Brand identifier from the agent’s brand.json brands array
fields	string[]	No	Optional sections to include (e.g., logos, colors, fonts, visual_guidelines, tone). Omit for all authorized sections. Core fields (brand_id, house, names) are always returned and do not need to be requested.
use_case	string	No	Intended use case (e.g., “endorsement”, “voice_synthesis”, “likeness”). Agent tailors content within the returned sections — a “likeness” use case returns action photos, a “voice_synthesis” use case returns voice configs. Does not override fields.

Valid fields values: description, industries, keller_type, logos, colors, fonts, visual_guidelines, tone, tagline, voice_synthesis, assets, rights

Recommended use_case values:

Value	Agent behavior
endorsement	Prioritize action photos, endorsement tone, brand story
voice_synthesis	Return voice synthesis config, pronunciation guides
likeness	High-res photos, appearance guidelines
creative_production	Full visual identity: colors, fonts, visual_guidelines, logos
media_planning	Basic identity and rights availability summary

use_case is advisory — it tailors content within returned sections but does not override fields.

Response

The response mirrors the brand.json brand definition, extended with dynamic data the agent controls:

Field	Type	Required	Description
brand_id	string	Yes	Brand identifier
house	object	Yes	House (corporate entity): domain and name
names	object[]	Yes	Localized names
description	string	No	Brand description
industries	string[]	No	Industries or categories
keller_type	string	No	Brand architecture type: master, sub_brand, endorsed, independent
logos	object[]	No	Brand logos (matches brand.json logo shape: url, variant, orientation, background, tags)
colors	object	No	Brand color palette with structured roles (primary, secondary, accent, background, text)
fonts	object	No	Brand typography. Keys are role names (primary, secondary). Values are a CSS font-family string or an object with family, files (array of {url, weight, weight_range, style}), opentype_features, and fallbacks
visual_guidelines	object	No	Photography, graphic style, colorways, type scale, motion rules, restrictions
tone	object	No	Brand voice and messaging guidelines. Sub-fields: voice (personality adjectives), attributes (prompt guidance traits), dos (approved approaches), donts (prohibited topics)
tagline	string	No	Brand tagline or slogan
voice_synthesis	object	No	TTS voice synthesis configuration (provider, voice_id, settings)
assets	object[]	No	Available brand assets — matches brand.json asset shape (asset_id, asset_type, url, tags)
rights	object	No	Rights availability summary (for pricing, use get_rights)
available_fields	string[]	No	Sections available but not returned due to authorization level. Tells the caller what linking their account would unlock.
