  9. Assess current architecture for scaling Free Crypto News

    main

    Before scaling to 1M+ users, evaluate the existing architecture against these key components and known gaps:

    Current Strengths

    • Edge runtime: ~82% of routes run on edge for low global latency.
    • Provider system: Uses fallback chains with circuit breakers for resilience.
    • Data Coverage: 163 RSS feeds + 77 international feeds.
    • Caching Strategy: 3-tier cache (in-memory → Redis → NGINX).
    • Load Balancing: Docker Compose setup with NGINX and rate limiting.

    Critical Gaps (Prioritized)

    • P0 (Immediate): Lack of a persistent database (causes data loss on restart) and lack of a job queue (relies on cron-based polling without retry/backpressure).
    • P1 (High): Single-region deployment (high latency), in-memory RSS fetching (memory pressure/SPOF), and lack of a full-text search engine.
    • P2 (Medium): Per-instance memory cache (causes inconsistency across replicas) and lack of an observability stack.

  10. Explore Free Crypto News MCP Tools

    main

    The Free Crypto News MCP server provides 59 tools that map directly to REST API routes. These tools allow an AI agent or user to interact with real-time cryptocurrency news, market data, DeFi metrics, derivatives, and on-chain information. The tools are categorized into several functional groups:

    • News: Latest headlines, breaking news, full-text search, article extraction, and historical archives.
    • Analysis: Trending topics, market narratives, sentiment analysis, and trading signals.
    • Market: Global market overview, coin prices, top gainers/losers, OHLC data, and price charts.
    • DeFi: TVL summaries, yield opportunities, stablecoin data, and gas prices.
    • Derivatives: Funding rates, liquidations, options data, and arbitrage opportunities.
    • On-chain: Whale alerts, exchange flows, token unlocks, and event calendars.
    • Reference: Exchange directories, news source lists, and macro indicators.
    • AI: News summarization, natural-language questions (ask_crypto), and daily AI briefs.
    • Provenance: Story clustering (grouping headlines into single events) and source leaderboards.
