Sundae UI MCP

An official Model Context Protocol server that allows coding agents to search the Sundae UI component library, retrieve documentation, and install React components via shadcn CLI commands. It supports both free and Pro assets, with entitlements checked server-side.

Endpoint and access

No sign-in to connect and list tools. Individual tools may still need a vendor account, credentials, or permissions; check the documented prerequisites.

Server-provided instructions

Untrusted server output shown for inspection. It is not Koskamo guidance and is excluded from knowledge search.

Sundae UI is a design-led library of React components, sections, effects, animations and templates. Workflow: search_components (or browse_category) → get_component for docs, props, variants and usage → get_install_instructions → get_component_source to obtain files. Write files under components/sundae/ and follow the usage example. Every result says whether it is free or pro. Pro source requires the user to have Sundae Pro ($80/year or $119 lifetime) and to configure their API token from https://sundaeui.dev/account#tokens as this server's Authorization header.

Connect from your client

Each snippet registers the same endpoint; pick the client you use.

This server is operated by the named third party. Listing and endpoint checks are not an endorsement or a security audit. Review the operator's permissions, terms, and data handling before connecting. How listings are checked and corrected.

Claude Code

Run this once in a terminal. It registers the remote server. Use --scope project to write .mcp.json for the repo.
Claude Code configuration
claude mcp add --transport http sundae-ui-mcp https://sundaeui.dev/api/mcp

Codex

Run this once. Codex stores MCP servers in ~/.codex/config.toml (or .codex/config.toml in a trusted project).
Codex configuration
codex mcp add sundae-ui-mcp --url https://sundaeui.dev/api/mcp

Cursor

Merge this server into .cursor/mcp.json in your project, then enable sundae-ui-mcp in your MCP settings.
Cursor configuration
{
  "mcpServers": {
    "sundae-ui-mcp": {
      "url": "https://sundaeui.dev/api/mcp"
    }
  }
}

Cline

Merge this into cline_mcp_settings.json (Cline → MCP Servers → Configure).
Cline configuration
{
  "mcpServers": {
    "sundae-ui-mcp": {
      "type": "streamableHttp",
      "url": "https://sundaeui.dev/api/mcp",
      "disabled": false
    }
  }
}

VS Code

Merge this server into .vscode/mcp.json. Use MCP: List Servers to start sundae-ui-mcp and inspect its tools.
VS Code configuration
{
  "servers": {
    "sundae-ui-mcp": {
      "type": "http",
      "url": "https://sundaeui.dev/api/mcp"
    }
  }
}

Gemini CLI

Run this once. It writes .gemini/settings.json in the current project; pass --scope user for ~/.gemini/settings.json.
Gemini CLI configuration
gemini mcp add --transport http sundae-ui-mcp https://sundaeui.dev/api/mcp

Claude Desktop

Open Claude Settings > Connectors > Add custom connector, enter this server URL and enable it for the conversation. This is a manual remote-connector handoff, not a desktop JSON configuration.
Claude Desktop configuration
https://sundaeui.dev/api/mcp

Windsurf

Merge this into ~/.codeium/windsurf/mcp_config.json, then refresh MCP in Cascade. Windsurf remote servers use serverUrl, not url.
Windsurf configuration
{
  "mcpServers": {
    "sundae-ui-mcp": {
      "serverUrl": "https://sundaeui.dev/api/mcp"
    }
  }
