marketsui-mcp

A local Model Context Protocol server that scaffolds new React or Angular apps preloaded with the Markets design system, @widgetstools/dock-manager, AG Grid (themed via DS adapters), and a dark/light theme toggle.

From any MCP-capable client (Claude Desktop, Claude Code, MCP Inspector, …) you can say:

scaffold markets react app at ~/apps/my-demo

and get a ready-to-run project with pinned deps, the full design-system/ tree, and a trading-style dock layout (bond blotter + candlestick chart + order book).

What you get

Each scaffolded app contains:

  • design-system/ — verbatim copy of the Markets DS (themes, adapters, cell renderers), as a sibling of src/.
  • libs/*.tgz — local tarballs for @widgetstools/dock-manager-core, the framework-specific dock manager, and (React) react-day-picker + tabby_ai-hijri-converter. Referenced as file:libs/*.tgz in package.json.
  • Theme toggle — top-right sun/moon button; flips data-theme on <html> and body.dataset.agThemeMode for AG Grid; persisted to localStorage.
  • Dock layout — 3 panels in a DockManagerCore (blotter / chart / order book) using sample data.
  • README with a Design System usage section (CSS imports, @design-system/* path alias, AG Grid + shadcn/PrimeNG adapters, CSS variable reference).

Install

Clone and build locally:

git clone <this-repo> marketsui-mcp
cd marketsui-mcp
npm install
npm run build

Optionally link the bin globally:

npm link          # exposes `marketsui-mcp` on PATH

Run

The server speaks MCP over stdio. You normally don't run it by hand — an MCP client launches it. For a quick sanity check:

npx @modelcontextprotocol/inspector node dist/index.js

Then in the inspector UI, invoke scaffold_markets_react_app with:

{ "name": "my-demo", "targetDir": "/tmp/scaffold-test", "runInstall": false }

Register with an MCP client

Claude Desktop

Edit ~/Library/Application Support/Claude/claude_desktop_config.json (macOS) or the equivalent on your platform:

{
  "mcpServers": {
    "marketsui": {
      "command": "node",
      "args": ["/absolute/path/to/marketsui-mcp/dist/index.js"]
    }
  }
}

If you ran npm link, you can use the bin directly:

{
  "mcpServers": {
    "marketsui": { "command": "marketsui-mcp" }
  }
}

Restart Claude Desktop. You should see the scaffold_markets_react_app and scaffold_markets_angular_app tools available.

Claude Code

claude mcp add marketsui -- node /absolute/path/to/marketsui-mcp/dist/index.js

Tools

scaffold_markets_react_app

Field Type Default Description
name string — App name (valid npm package name).
targetDir string — Parent directory; app is created at <targetDir>/<name>. Absolute paths recommended.
runInstall boolean false If true, runs npm install inside the new app.

Returns { path, framework: "react", nextSteps: [...] }.

scaffold_markets_angular_app

Same input shape; produces an Angular 21 + PrimeNG + AG Grid app. Returns { path, framework: "angular", nextSteps: [...] }.

Example session

user: scaffold markets react app called demo at /tmp/scaffold-test

assistant: (calls scaffold_markets_react_app)

→ /tmp/scaffold-test/demo
  cd /tmp/scaffold-test/demo
  npm install
  npm run dev

The dev server boots at http://localhost:5173, shows the dock layout, and the top-right toggle switches between dark and light themes.

To refresh pinned versions, re-copy design-system/ and re-run npm pack on the dock-manager packages, then drop the tarballs into templates/{react,angular}/libs/ and regenerate the matching package-lock.json.
