Overview

AI-generated overview

CardNexus is a remote MCP server that lets an assistant search trading card prices, build carts and manage a CardNexus store.

What you can do
Search trading card prices and product information across the CardNexus catalog, and assemble carts from the results. Manage a CardNexus store through the assistant. Payment for purchases is completed on the CardNexus website rather than inside the assistant.
When to use it
Useful for collectors or store operators who want an assistant to look up trading card prices, put together carts, or handle CardNexus store management tasks without switching to the site for browsing.
Requirements
A remote MCP endpoint at mcp.cardnexus.com using streamable HTTP. OAuth authentication is required, so a CardNexus account sign-in is needed. No environment variables or headers are declared.
Before you install
Purchases involve real money: payment is made on cardnexus.com, so check carts and totals before completing checkout. Store management actions may change listings or other store data. OAuth grants the server access to your CardNexus account.

Installation

In SourceWeft

  1. Open CardNexus in the dashboard and add it to a workspace.
  2. Connect the required credentials. They are stored privately and never shown on public pages.
  3. Enable the server for the chats that should use its tools.

Web executable via Streamable HTTP. Remote servers run from the web runtime once configured in a workspace.

Use with an agent

Paste this prompt into Claude Code, Codex, Cursor or another agent — or into SourceWeft chat. The agent reads this server's install guide, shows you its publisher, endpoint and sign-in, and adds it to your client once you agree. Keys never go into a command.

Read https://sourceweft.com/mcp/com.cardnexus%2Fmcp/install.md and connect the MCP server it describes to my client. Before changing any config, show me its publisher, endpoint and sign-in method and wait for my OK. Never put an API key in a command or in a file I would commit; ask me where it should come from.

Read the install guide the agent follows

Other MCP clients

Add this to your client's mcpServers config. The client completes OAuth sign-in on first connect.

Tools

This server asks you to sign in, so SourceWeft could not read its tools without an account and has not indexed them. What a connected account sees can depend on that account and its permissions.

How complete this listing is, computed from the registry entry, the endpoint and public sources. Not a rating of the server and not a statement that it is safe or working today: reachability is a dated check, and no installs or reviews go into the score.
