Nansen Web Searcher

This lets Claude search the web through Serper API when you need current information to pair with Nansen's on-chain data. You can run multiple queries in parallel, get up to 20 results per query, and it filters out paywalled sites like Bloomberg and Twitter automatically. Returns clean JSON with titles, links, snippets, and sometimes knowledge graph data. It's meant for grabbing fresh context like token prices, news, or ecosystem updates before diving into the blockchain analytics. If you need full page content from specific URLs, there's a separate fetch command for that.

Authentication

Nansen account API calls accept a selected nansen:api browser session or conventional API key with the same permissions. NANSEN_API_KEY takes precedence; optional primaryEnv preserves configured-key injection. Run nansen auth status for offline selection. Cached access expiry alone permits automatic renewal during an authorized task. Stop on anonymous selection, invalid state, blocked/uncertain renewal or actual auth failure; never drop a credential or fall back to anonymous x402 payment. Browser login does not grant wallet signing, privileged service identity or a persistent MCP integration key. Preserve all confirmation, signing, sanctions and geographic checks below. Browser login is enabled in production within the documented platform scope.
