Details

From the project README

CoinGecko Historical

Open a validated one-day window around the requested date in Chromium.

Workflow

  1. Require a CoinGecko coin ID and an ISO date (YYYY-MM-DD). Resolve a supplied name or symbol with cg search <term> -o json before continuing.

  2. Build the URL with the portable helper:

    uv run <skill-dir>/scripts/build-url.py <coin-id> <date>

    Invalid IDs or calendar dates exit nonzero without opening a page.

  3. Pass the returned URL to mcp__chrome_devtools.new_page with background: false.

  4. Completion is the successfully opened page URL. Do not use the macOS open command.
