BranderUX MCP

The official BranderUX MCP server. It gives an AI agent real control over BranderUX projects — brand, custom elements, screens, API keys — plus the verified reference docs it needs to integrate the SDK correctly.

Connect: https://mcp.branderux.com/mcp · Docs: https://branderux.com/mcp

No API keys: the first tool call opens your browser for a one-click BranderUX sign-in (OAuth 2.1 + PKCE, scoped and revocable). Access is currently limited to design partners — everyone else lands on the waiting list.

Tools

Knowledge (no scopes needed — signing in is still required to reach the server): get_started · read_doc · search_docs · get_integration_snippet

Projects (projects:*): whoami · list_projects · get_project · create_project · update_brand_settings · update_project_settings · delete_project

Screens (projects:write): list_screens · get_screen · put_screen · delete_screen — custom screens live on the project aggregate; these tools do the read-modify-write for you.

Custom elements (elements:*): list_elements · get_element · create_element · publish_element_version · preview_element · delete_element — your agent writes the TSX; the server pre-flight validates it (compile + sandbox import allowlist + export contract) before publishing. In clients that support MCP Apps, create_element, publish_element_version and preview_element render the element LIVE in the panel — demo props applied, clicks showing the exact query they would send.

API keys (keys:manage): create_api_key · list_api_keys · set_key_origins · revoke_api_key

Every destructive tool requires an explicit confirm: true.

Local development

npm install
BRANDER_API_BASE=http://localhost:8080/api/v1 npm run dev   # http://localhost:3010/mcp

Env	Default	Purpose
BRANDER_API_BASE	http://localhost:8080/api/v1	BranderUX API base
MCP_RESOURCE_URL	http://localhost:3010	Public URL of this server (OAuth resource id)
OAUTH_ISSUER_URL	= BRANDER_API_BASE	Authorization server issuer

The server is stateless: one MCP server instance per request, bound to the caller's bearer. Deploy target is Vercel (api/mcp.ts + api/oauth-protected-resource.ts).
