AI Developer Tools MCP Server

/** * Trending Tool * * Shows the fastest-growing AI developer tools over a specified time period. * * Design Decisions: * - Focuses on growth rate rather than absolute numbers (more interesting signal) * - Limits results to prevent overwhelming the user * - Sorts by growth % to highlight emerging tools * * This demonstrates a pattern where the tool performs calculations/aggregations * rather than just returning raw data. The AI agent gets insights, not just numbers. */ import { CURRENT_METRICS, TOOLS, getGrowthMetrics, getToolsByMetric } from '../data/mock-data.js'; export const trendingTool = { name: 'get_trending_tools', description: 'Get the fastest-growing AI developer tools over a time period, ranked by adoption growth rate', inputSchema: { type: 'object', properties: { time_range: { type: 'string', enum: ['7d', '30d', '90d'], default: '30d', description: 'Time period to analyze for growth trends' }, limit: { type: 'integer', minimum: 3, maximum: 10, default: 5, description: 'Maximum number of tools to return (3-10)' }, category: { type: 'string', enum: ['llm-api', 'editor', 'assistant', 'framework', 'all'], default: 'all', description: 'Filter by tool category, or "all" for no filter' } } }, async execute(args) { const { time_range = '30d', limit = 5, category = 'all' } = args; // Get all tools with their current metrics let toolsList = getToolsByMetric('npm_downloads_monthly'); // Filter by category if specified if (category !== 'all') { toolsList = toolsList.filter(t => t.category === category); } // Calculate growth for each tool const months = time_range === '90d' ? 3 : 1; const toolsWithGrowth = toolsList.map(tool => { const growth = getGrowthMetrics(tool.id, months); return { ...tool, growth_pct: growth?.growth_pct || 0, current_downloads: growth?.current || tool.npm_downloads_monthly }; }); // Sort by growth rate (descending) toolsWithGrowth.sort((a, b) => b.growth_pct - a.growth_pct); // Take top N const trending = toolsWithGrowth.slice(0, limit); // Format output let output = `🚀 Trending AI Developer Tools\n`; output += `📅 Period: ${time_range}`; if (category !== 'all') { output += ` | Category: ${category}`; } output += `\n\n`; // Rankings output += `**Fastest Growing**\n`; trending.forEach((tool, index) => { const rank = index + 1; const growthIcon = tool.growth_pct > 50 ?
