This is the third-party server itself — Odel doesn't run it. Hitting this URL directly talks straight to the upstream server with no auth or proxying. Connect through Odel to front it with managed auth.

NDEX Pricing — MCP connector

Swiss market prices for video games and consoles, with provenance, served to any MCP client from https://www.nd-x.app/api/mcp. Read-only: two tools, one scope, no writes.

ToolWhat it does
search_ndex_catalogFind a game or console in the NDEX catalog (platform disambiguates homonyms).
get_ndex_estimateSwiss observed prices and external PAL references, kept separate, with sample size, freshness and confidence.

The skill in skills/ndex-pricing/ teaches the model how to use them: identify first, never average sources of different provenance, say when the price is unknown.

Connect

ChatGPT, claude.ai, Claude Desktop — add https://www.nd-x.app/api/mcp as a connector. The server is its own OAuth 2.1 authorization server (PKCE S256, Client ID Metadata Documents, dynamic registration as fallback). You sign in with your NDEX account and consent once.

In ChatGPT, a remote server is registered through developer mode (Plugins → new connection with the URL above); ChatGPT assigns it an id starting with plugin_asdk_app_. A ChatGPT / Codex plugin then references that registration through an .app.json file named by the apps field of .codex-plugin/plugin.json. This repository ships the manifest and the skill; the .app.json is produced at registration time, so it is not committed here.

Claude Code — install this plugin, or add the server directly:

claude mcp add --transport http ndex-pricing https://www.nd-x.app/api/mcp

Claude Code identifies itself with its Client ID Metadata Document and completes the OAuth flow in your browser. No token to paste.

Codex, Cursor, VS Code, Gemini CLI, Windsurf, Zed, Warp — point the client at the same URL. Clients that only support a static header can use a beta bearer token, handed out on request at nd-x.app/mcp.

Layout

  • .claude-plugin/plugin.json — Claude Code / Cowork plugin manifest (skill + remote MCP server in .mcp.json).
  • .codex-plugin/plugin.json — ChatGPT / Codex plugin manifest (skill; the remote server is attached through apps → .app.json once registered in ChatGPT, see above).
  • server.json — entry for the official MCP registry, published as app.nd-x/ndex-pricing.
  • skills/ndex-pricing/SKILL.md — the skill, in French (the model follows it in any language).

Privacy and terms

nd-x.app/privacy. The connector reads catalog and price data only; it never touches your collection, your account, or the conversation.
