Overview

Description from the maker (original English)

ChatGPT, Claude, Gemini, Perplexity and Grok subscription prices by country, with price history.

PopNx MCP’s three pillars

These three are never merged into one score: opinions, measurements and popularity are different things.

What you can do with it

We have not written a plain-language summary for this one yet. Below are the facts we read from the registry.

  • Connection: Runs in the cloud
  • Transport: Streamable HTTP
  • Category: Search & AI memory

Install

Pick the AI app you use, then copy the settings.

ChatGPT connects only to servers on the internet:

  1. Open ChatGPT on the web → Settings → Connectors (Apps)
  2. Press Create or Add (some plans need Developer mode under Advanced first)
  3. Paste the address below, give it a name and save

Menu names can differ slightly by plan and over time.

Your choice stays on this device in a cookie; no account needed.

These settings are generated from the maker’s registry entry. If the README says otherwise, follow the README.

Common questions

Is AISub safe?

It passed 2 of 3 applicable basic checks. We have not read the code. Before adding a key or token, see what access the server asks for and use a key with only the permissions you need.

What keys or codes does it need?

The registry does not list a required key, though some servers ask you to sign in on first use.

Does it run on my computer or in the cloud?

It runs in the maker’s cloud. Connect over the internet with nothing to install, but what you send passes through the maker’s servers.

Is it still maintained?

The GitHub repo last changed –, and the latest version (1.0.0) reached the registry 8 days ago.

Which apps can use it?

Apps that support MCP, such as Claude Desktop, Claude Code, Cursor and VS Code. It connects by URL, so apps that accept remote MCP servers work too, such as ChatGPT in developer mode.

What can I use instead?

In the same category: Context7, Codebase Memory, Exa

Setup

Claude: in Settings → Connectors, add a custom connector with the URL above.

ChatGPT: turn on developer mode in Settings, create a connector with the URL above and choose no authentication.

Cursor and similar clients:

{

"mcpServers": { "aisub": { "url": "https://aisub.yuanwu.ai/mcp" } } }

VS Code (mcp.json):

{

"servers": { "aisub": { "type": "http", "url": "https://aisub.yuanwu.ai/mcp" } } }

Clients that only run local (stdio) servers:

{

"mcpServers": { "aisub": { "command": "npx", "args": ["-y", "mcp-remote", "https://aisub.yuanwu.ai/mcp"] } } }

Example questions

  • How much is Claude Pro in Japan, and is it cheaper than in the US?
  • Which countries changed ChatGPT prices in the last 30 days?

Limits and privacy

Each source IP can make up to 120 requests per minute. AISub keeps only daily totals of tool calls by tool and client type; it does not store IP addresses, query arguments or responses. See the privacy policy.

Prices are for reference. Whether you can buy a plan and the final amount are confirmed at the provider's checkout.

Publishing to the MCP Registry

This repository holds the server.json listed in the official MCP Registry. The server code runs on AISub and is not part of this repository.

Maintainers publish with mcp-publisher, using DNS authentication for yuanwu.ai:

  1. Generate an Ed25519 key pair and add the TXT record v=MCPv1; k=ed25519; p= at the apex of yuanwu.ai. See the registry's authentication guide. Keep the private key out of this repository.
  2. Bump version in server.json and run mcp-publisher validate.
  3. Run mcp-publisher login dns --domain yuanwu.ai --private-key , then mcp-publisher publish.
