What you can do with it

We have not written a plain-language summary for this one yet. Below are the facts we read from the registry.

Connection: Runs in the cloud
Transport: SSE
Category: Design, images & audio
You need to fill in: Authorization

Install

Pick the AI app you use, then copy the settings.

Before you install

Basic checks: 1 of 1 passed
Runs on the maker’s server: what you ask it goes through their server.
You fill in yourself: Authorization

Values marked secret are keys to your account. Never share them or paste them into a chat.

You need

Runs in the cloudNothing to install; it connects over the internet

Which app do you use?

ClaudeClaude CodeCursorVS CodeChatGPT

Pick your app above. We remember it, so next time the button says “Install in …”.

This address needs a key in a request header, which the add-connector menu cannot set. Use Claude Code, Cursor or VS Code instead.

Run this in your terminal

claude mcp add --transport sse basalt https://basalt.run/api/mcp --header 'Authorization: your-value'

Fill in the empty values before running it.

Open in Cursor

Or copy the settings yourself

Paste into .cursor/mcp.json in your project, or ~/.cursor/mcp.json

{
  "mcpServers": {
    "basalt": {
      "url": "https://basalt.run/api/mcp",
      "headers": {
        "Authorization": "your-value"
      }
    }
  }
}

Your browser asks to open the app, then the app shows the settings and asks you to confirm. Key values are left empty for you to fill in.

Open in VS Code

Or copy the settings yourself

Paste into .vscode/mcp.json in your project

{
  "servers": {
    "basalt": {
      "type": "sse",
      "url": "https://basalt.run/api/mcp",
      "headers": {
        "Authorization": "your-value"
      }
    }
  }
}

Common questions

Is Basalt safe?

It passed 1 of 1 applicable basic checks. We have not read the code. Before adding a key or token, see what access the server asks for and use a key with only the permissions you need.

What keys or codes does it need?

You need to fill in: Authorization

Does it run on my computer or in the cloud?

It runs in the maker’s cloud. Connect over the internet with nothing to install, but what you send passes through the maker’s servers.

Is it still maintained?

The GitHub repo last changed –, and the latest version (1.0.0) reached the registry 7 months ago.

Which apps can use it?

Apps that support MCP, such as Claude Desktop, Claude Code, Cursor and VS Code. It connects by URL, so apps that accept remote MCP servers work too, such as ChatGPT in developer mode.

What can I use instead?

In the same category: Figma Context MCP, Claude Real Video, Figma MCP Server

Basalt Design System

Design tokens in Git. Readable by AI. Beautiful to edit.

This repo is managed by Basalt — a design system platform that stores tokens, components, and documentation in Git and serves them to AI coding tools via MCP.

What's in this repo

tokens/

├── primitives.json # Raw values (colors, spacing, radii) ├── semantic.light.json # Light theme semantic tokens └── semantic.dark.json # Dark theme semantic tokens

All tokens use the DTCG 2025.10 format (W3C standard).

Using these tokens with AI tools

Basalt serves this design system to Cursor, Claude Code, Claude Design, and Windsurf via an MCP server. AI tools query your real token values instead of guessing.

See [MCP.md](MCP.md) for setup instructions and available tools.

Quick config (Cursor / Claude Code / Windsurf):

"mcpServers": { "basalt": { "url": "https://basalt.run/api/mcp", "headers": { "Authorization": "Bearer bsk_your_key_here" } } } }

Get a free API key at basalt.run.

Token architecture

Three tiers, each referencing the layer above:

Primitive → raw values (color.orange.500 = #F97316) Semantic → intent + theming (color.action.default → color.orange.500) Component → scoped to UI elements (button.background.default → color.action.default)

AI tools resolve the full chain automatically via MCP.
