Tools

Refero MCP gives your agent tools for three research layers:

Styles — visual direction, taste, tokens, typography, spacing, surfaces, imagery, and component feel.
Screens — concrete UI patterns, page structure, copy, states, and product-specific details.
Flows — multi-step journey logic: goals, actions, system responses, friction, and completion states.

For visual design work, start with styles. Use screens for concrete interface decisions. Use flows when the task has a before/after sequence.

Styles

`refero_search_styles`

Search curated design styles using semantic search. Use this first when you need visual direction, brand feel, typography, color, layout, spacing, elevation, surfaces, components, imagery, or design-system inspiration. Parameters

Parameter	Type	Required	Description
`query`	string	yes	A semantic query for aesthetic, domain, audience, product category, or brand direction. Minimum 2 characters.
`page`	number	no	Pagination. Default: `1`.
`response_format`	`"md"` \| `"json"`	no	Response format, when supported by your MCP client. Default: `"md"`.

      "description": "A dark, high-contrast developer-tool landing page..."
    }
  ]
}

Search several visual angles before choosing a direction. Styles are reference ingredients, not templates to copy.

`refero_get_style`

Retrieve full design guidance for one or more style UUIDs. Use this after refero_search_styles. Parameters

Parameter	Type	Required	Description
`style_id`	string	yes*	One style UUID. Use exactly one of `style_id` or `style_ids`.
`style_ids`	string[]	yes*	Multiple style UUIDs. Maximum 10; 3-4 per batch is recommended because full styles are large.
`response_format`	`"md"` \| `"json"`	no	Response format. Default: `"md"`.

What you get

north star / visual thesis
color roles, not just hex values
typography roles and type scale
spacing, radius, shadows, elevation, and surfaces
layout and section rhythm
component treatments and sometimes implementation snippets
imagery, graphics, illustration, or product screenshot guidance
do/don’t rules and agent prompt guidance

Styles currently focus on web marketing and product pages: landing pages, pricing pages, product marketing sites, editorial brand sites, and SaaS websites. They are still useful for product UI work, but use screens and flows for product-specific behavior.

Screens

`refero_search_screens`

Search real UI screens for concrete interface decisions: page structure, component choices, content hierarchy, states, copy, and product patterns. Parameters

Parameter	Type	Required	Description
`query`	string	yes	Search by screen type, UI element, pattern, state, company, or on-screen text. Minimum 2 characters.
`platform`	`"web"` \| `"ios"`	yes	Platform filter.
`page`	number	no	Pagination. Default: `1`.
`response_format`	`"md"` \| `"json"`	no	Response format, when supported by your MCP client. Default: `"md"`.

Common mistakes

Do not use old _tool suffixed names.
Do not call get_design_guidance; use styles, screens, and flows.
Do not pass image_size or include_similar to refero_get_screen.
Do not use numeric screen IDs. Screens use UUIDs.
Do not use screens as the main source for visual taste when styles are available.
Do not copy a single style directly.

Data Model

Field reference for styles, screens, and flows.
