Blocklens — Professional Crypto On-Chain Analytics

# Blocklens > Bitcoin on-chain analytics platform — 210+ metrics, REST API, MCP server, interactive charts, heatmap rendering. Blocklens provides Bitcoin on-chain analytics derived from self-hosted full nodes with raw UTXO-level analysis since the genesis block (2009). Also tracks Bitcoin ETF data across 27 global ETF products. ## AI Integration (MCP) **Recommended way to access Blocklens data from AI assistants:** ### Remote MCP Server (No Install) Connect directly to the hosted endpoint — no packages, no local setup: - **Endpoint:** `https://mcp.blocklens.co` (Streamable HTTP transport) - **Claude.ai:** Settings → Connectors → Add → URL: `https://mcp.blocklens.co` - **Claude Desktop (via mcp-remote):** ```json { "mcpServers": { "blocklens": { "command": "npx", "args": ["mcp-remote", "https://mcp.blocklens.co"] } } } ``` ### Local Install (Alternative) Install via npm for stdio-based MCP clients: ``` npx blocklens-mcp-server ``` Or add to your MCP config (Claude Desktop, Cursor, etc.): ```json { "mcpServers": { "blocklens": { "command": "npx", "args": ["blocklens-mcp-server"] } } } ``` Both methods provide the same 19 tools covering all Blocklens analytics — no API key needed for demo-tier data. ### Key MCP Capabilities - **render_chart**: Generate PNG chart images with any metric combination - **Cycle overlay charts**: Compare Bitcoin cycles using `x_axis: "day_offset"` — all cycles start at Day 0 for visual comparison. Metrics: cycle_ath_1..5, cycle_low_1..4, cycle_halving_1..4 - **Heatmap rendering**: Cost basis distribution heatmap via `heatmap_id: "cost-basis-distribution"` with viridis/soft/plasma color scales - **Formulas**: Compute derived metrics (ratios, differences) with `m1 / m2` expressions - **Custom axes**: Multi-axis charts with vertical zones, reference lines, shaded areas - Remote endpoint: https://mcp.blocklens.co - npm: https://www.npmjs.com/package/blocklens-mcp-server -
