Example: Budget Allocator App

An interactive budget allocation tool demonstrating real-time data visualization with MCP Apps.

Initial Over budget Tech-heavy

Features

  • Interactive Sliders: Adjust budget allocation across 5 categories (Marketing, Engineering, Operations, Sales, R&D)
  • Donut Chart: Real-time visualization of allocation distribution using Chart.js
  • Sparkline Trends: 24-month historical allocation data per category
  • Percentile Badges: Compare your allocation vs. industry benchmarks
  • Stage Selector: Switch between Seed, Series A, Series B, and Growth benchmarks
  • Budget Presets: Quick selection of $50K, $100K, $250K, or $500K totals

Running

  1. Install dependencies:

    npm install

  2. Build and start the server:

    npm start

    The server will listen on http://localhost:3001/mcp.

  3. View using the basic-host example or another MCP Apps-compatible host.

Architecture

Server (server.ts)

Exposes a single get-budget-data tool that returns:

  • Category definitions with colors and default allocations
  • Historical data (~120 data points) - 24 months of allocation history per category
  • Industry benchmarks (~60 data points) - Aggregated percentile data by company stage

The tool is linked to a UI resource via _meta[RESOURCE_URI_META_KEY].

App (src/mcp-app.ts)

  • Uses Chart.js for the donut chart visualization
  • Renders sparkline trends using inline SVG
  • Computes percentile rankings client-side from benchmark data
  • Updates all UI elements reactively on slider changes
