Security note

MCP servers receive tool arguments from a conversation and may perform external actions. Review what a server can do before you enable it, and give it only the access it needs.

The registry verified the GitHub account hurcanNansen for this listing. That does not show the account is the product's maker.

SourceWeft's checks cover whether the listing is complete and the endpoint answered; they do not review the server's code or what its tools do.

Overview

AI-generated overview

A deprecated Nansen MCP server that has been moved to another registry entry; it is marked as not to be used.

What you can do: The registry description states the server is deprecated and has been moved to a different identifier, io.github.nansen-ai/nansen-mcp, and advises against using it. No tools, instructions or README are provided, so no capabilities can be described. Anyone looking for Nansen functionality should use the successor entry instead.
When to use it: Not intended for use. The description explicitly says it is deprecated and should not be used; look for the successor server under the new identifier instead.
Requirements: Runs as a local process over stdio. No packages, environment variables, headers or authentication are declared, and no setup details are given.

Before you install

The description marks this server as deprecated and says not to use it, so it should not be installed. No credentials, data handling or write actions can be assessed from the available information.

Installation

In SourceWeft

Open Nansen (DEPRECATED) in the dashboard and add it to a workspace.
Enable the server for the chats that should use its tools.

Desktop only via STDIO. STDIO servers start a local process, so they need the SourceWeft desktop host.

Tools

SourceWeft has not started this package in its sandbox yet, so its tools are not known.
