Nomina v1.2.0

v1.2.0 answers questions that need exact dates rather than fixed lookback periods, adds a one-call market snapshot, reports drawdown and volatility for a researched series, and caches identical provider requests for 60 seconds. All tools remain read-only.

What’s new

• research_asset and compare_assets accept start and end (YYYY-MM-DD, inclusive) for an exact window instead of period; responses report period as start..end. Windows are limited to 25 years and cannot end in the future.
• New tool market_overview: period returns for ^GSPC, ^IXIC, ^DJI, ^RUT, ^VIX, ^TNX, DX-Y.NYB, GC=F, CL=F, BTC-USD, ETH-USD, and EURUSD=X, with failed members listed individually.
• research_asset returns statistics: observation count, maximum drawdown, and annualized volatility of the returned series (sample standard deviation of log returns, √252 daily or √52 weekly). Descriptive only; not forecasts.
• Identical Yahoo Finance requests within 60 seconds reuse the previous response, reducing provider rate limiting during multi-step research.

Install

• Claude Desktop: download Nomina.mcpb from the release and install it via Settings → Extensions → Advanced settings → Install Extension.
