Is it still maintained?

The GitHub repo last changed –, and the latest version (0.4.3) reached the registry 8 months ago.

Which apps can use it?

Apps that support MCP, such as Claude Desktop, Claude Code, Cursor and VS Code. You also need Node.js on your computer.

render_chart({ template: "mvrv_ratio" }) render_chart({ metrics: ["lth_supply", "sth_supply"], style: "area" }) render_chart({ metric: "dormancy_flow", overlay: "price" }) render_chart({ template: "realized_volatility", days: 730 })

Annotations — reference lines and areas:

render_chart({

metric: "lth_mvrv", reference_lines: [ { "y": 3.5, "label": "Overheated", "stroke": "#ef4444", "dash": "3 3" } ], reference_areas: [ { "y1": 0, "y2": 0.85, "label": "Undervalued", "fill": "#22c55e", "fill_opacity": 0.15 } ] })

Example Prompts

"What's Bitcoin's current MVRV ratio and what does it say about valuation?"
"Show me realized volatility — is short-term vol higher than long-term?"
"Chart dormancy flow with price overlay for the last 2 years"
"Compare LTH and STH supply trends over 90 days"
"Are long-dormant coins waking up? Check liveliness and CDD"
"Show cycle performance from each halving — are we tracking historical patterns?"
"What's the current NUPL level? Is the market in euphoria or fear?"
