Nansen Portfolio Tracker
This pulls wallet portfolio data from Nansen's API to show you how holdings have changed over time. You get historical balances going back 30 days, a current snapshot of what's in the wallet right now, and per-token PnL with realized gains, ROI, and buy/sell counts. Useful when you're tracking how a whale or protocol treasury has been rotating positions, or when you want to see actual performance numbers instead of just current balances. The PnL breakdown showing buys, sells, and remaining holdings is genuinely helpful for understanding trading behavior. Requires a Nansen API key and works across Ethereum and other chains they support.

Authentication
Browser login requests nansen:api for API-key-equivalent account API permissions; existing OAuth/MCP nansen:read semantics and separate wallet authorization are unchanged.
Before any research command or loop, require an explicitly selected API key or saved browser session. Run nansen auth status first. Its cached/unverified metadata does not prove credential validity or unlocked storage. Cached access-token expiry alone does not mean the session is unusable: the CLI normally renews a selected session automatically during an already-authorized research task, without another consent request or a separate account check. Stop on anonymous selection, invalid authentication state, blocked or uncertain renewal/cleanup, or an actual authentication failure, including rejected or expired refresh authority. Follow the CLI error guidance; use the free nansen account check when troubleshooting calls for it. Do not unset a failed key, erase a session or switch to anonymous access to retry.
