Blocklens Mcp Server

blocklens/blocklens-mcp-server

Connects Claude to Blocklens's Bitcoin on-chain analytics engine with 127 metrics computed from raw blockchain data. You get 15 tools covering market data, supply distribution, valuation models (MVRV, NUPL, SOPR), HODL waves across 12 age cohorts, coin days destroyed, liveliness, dormancy flow, and cycle performance indexed from halvings and ATHs. The render_chart tool generates annotated PNGs inline for any metric or combination. Works in demo mode without an API key (60 days of basic metrics), or connect with a Pro/Enterprise key for full history and LTH/STH breakdowns. Reach for this when you're analyzing Bitcoin market cycles, holder behavior, or on-chain valuation models and need Claude to pull live data and generate charts in conversation.
