Nansen is a Model Context Protocol (MCP) server: Blockchain analytics API for AI agents. Smart Money signals, wallet profiling, token analytics. In practice that means any MCP-compatible AI assistant can call Nansen's tools directly — the model decides when to use them in a conversation or agent run.
It's a hosted (remote) server — point your client at https://mcp.nansen.ai/ra/mcp/ and you're connected, with nothing to install locally. The current release is v1.0.1.
Nansen is listed under Finance on mcp.site and works with any MCP client — Claude Desktop, Claude Code, Cursor, VS Code, Windsurf, Zed and the rest of the ecosystem — using the install snippets below.
