* Add bun as devDependency to example packages

npm install now automatically installs bun, eliminating the need for
separate installation instructions. Removed manual bun install step
from customer-segmentation-server README.

* Add start:http and start:stdio npm scripts to examples

For the 6 examples supporting --stdio transport, add explicit scripts:
- serve:http / serve:stdio for running the server
- start:http / start:stdio for build + serve
- start now aliases to start:http for backward compatibility

Update READMEs to document both transport options.

Raw Blame History

Example: Budget Allocator App

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

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

Install dependencies:
```
npm install
```

Build and start the server:

npm run start:http  # for Streamable HTTP transport
# OR
npm run start:stdio  # for stdio transport

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
