chord-charts

chord-charts is a skill for Claude Code from tuantqse90/moltnode-mcp. It costs 121 tokens per session (840 once invoked), scanned A, original, MIT.

A tool that creates SVG candlestick charts with volume from decentralised-exchange trades for supported tokens and chains. Candlesticks show price movement over a chosen time period, while volume shows how much was traded.

In plain words
What is it for?
Use it to chart tokens, tokenised stocks, or other supported assets over intervals such as minutes, hours, or days, using a symbol or token address.
Why use it?
It turns exchange trade data into a standalone chart and a summary of the price move, highs, lows, volume, and trade count.

Token cost

What it costs to keep this loaded

Counted locally with the o200k_base tokenizer, which is exact for GPT models; Claude uses its own tokenizer and its counts differ. Treat this as one consistent yardstick across the catalogue rather than a bill. Prices are per million input tokens.

Security

Grade A, and why

chord-charts scanned grade A with 0 findings against 26 rules in 11 categories — prompt injection, anti-refusal, data exfiltration, privilege escalation, supply chain, agent snooping, system-prompt leakage, SSRF and excessive agency — measured 11d ago.

The scan reads SKILL.md. This mod also ships 1 executable file (scripts/chart.py), listed below but not scanned — reading those needs a real analyzer, not pattern matching.

A static scan of the body, not an audit. Every finding is printed with the line that produced it so you can judge whether it matters here. A mod is markdown that instructs an agent; that is exactly why what it instructs is worth reading.

Nothing flagged

None of the 26 patterns this scan looks for appear in this file: no shell pipes, no recursive deletes, no credential paths, no hidden text, no instruction-override or anti-refusal phrasing, no agent-config snooping. That is not a guarantee, it is the absence of the things that are checkable.

The opening of the file, as written. The whole thing — 39 lines — stays where its author put it; the contents beside it link to each section on GitHub.

Chord charts

Chord indexes every DEX swap on its chains and builds candles from those trades. scripts/chart.py turns them into a standalone SVG candlestick chart and prints a JSON summary.

Draw a chart

python3 scripts/chart.py --chain base --token AERO --tf 1h --limit 48
python3 scripts/chart.py --chain solana --token BONK --tf 15m --limit 96
python3 scripts/chart.py --chain robinhood --token NVDA --tf 1d --limit 60
python3 scripts/chart.py --chain arbitrum --token 0x912ce59144191c1204e64559fe8253a0e49e6548 --tf 4h --limit 42 --out arb.svg
  • --chain: ethereum, base, monad, bnb, avalanche, arbitrum, robinhood, arc, solana.
  • --token: a symbol or name, or an address (0x… on EVM chains, the base58 mint on Solana, case-sensitive). A symbol is resolved through Chord's search; the script prints the address it picked. Similar tickers are common: if the user named a token loosely, show them the resolved address.
  • --tf: 1m 5m 15m 1h 4h 1d 1w (Solana up to 1d). --limit: number of candles, up to 1000.
  • Output: the SVG file (path in the summary, default chart-<symbol>-<chain>-<tf>.svg) and a JSON summary on stdout: symbol, token, open, close, changePct, high, low, volumeUsd, trades, lastCandleOpen.

Show the user the chart file and a one-line read of the summary, for example: "AERO on Base, last 48 hours: $0.884, -2.75%, range $0.831 to $0.920, $10.5M traded."

Notes

  • Prices are in USD from on-chain trades. Wrapped majors stand in for the coin: WETH for ETH, cbBTC on Base, BTC.b on Avalanche, BTCB on BNB Chain, WMON on Monad. Say which token you charted.
  • Robinhood Chain stock tokens trade around the clock on-chain, so their candles can move while the US market is closed.
  • Solana candles are one pool's prices (the main pool), not a blend across pools.
  • If the last candle is still open, lastCandleOpen is true and the subtitle says so.
  • About 60 requests a minute without a key; a chart costs one or two requests.
  • For raw data without a chart: GET https://api.getchord.xyz/v1/candles?chain=<chainId>&token=<address>&tf=1h&limit=48 (EVM) or GET https://api.getchord.xyz/v1/chains/solana/token/<mint>/candles?tf=1h&limit=48.

What ships with it

1 file beside SKILL.md in the same directory: the scripts, references and assets a skill reads on demand. Not counted in the per-session cost; read them before you install if any of them is executable.

Changes

What this file has done since we first saw it

Hashed on every crawl. A supply-chain change to an agent config is a question of when, not whether, so the history is kept rather than the latest state alone.

chord-charts is a skill published in the GitHub repository tuantqse90/moltnode-mcp (1 stars, last pushed 7d ago), licensed MIT. It adds 121 tokens to every session and 840 once invoked, about $0.0005 per session on Opus 5.5. A static security scan graded it A with 0 findings. No closer match exists in the catalogue, so it is treated as the original; first seen 2026-10-16.
