MCP Client Configuration Add to your MCP client configuration (stdio transport): { "mcpServers" : { "budget-allocator" : { "command" : " npx " , "args" : [ " -y " , " --silent " , " --registry=https://registry.npmjs.org/ " , " @modelcontextprotocol/server-budget-allocator " , " --stdio " ] } } } Local Development To test local modifications, use this configuration (replace ~/code/ext-apps with your clone path): { "mcpServers" : { "budget-allocator" : { "command" : " bash " , "args" : [ " -c " , " cd ~/code/ext-apps/examples/budget-allocator-server && npm run build >&2 && node dist/index.js --stdio " ] } } } 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.ui.resourceUri . 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 Footer (c) 2026 GitHub, Inc.
