Connect PopNx MCP to your AI

Let Claude, ChatGPT or Codex search the 59,000+ MCP servers in the registry, compare them, get install steps and read skills right inside your chat. Your AI does the thinking; we supply data refreshed every 30 minutes. Free, no sign-up, read-only.

Server URL

Every app uses this same URL (Streamable HTTP MCP, no key needed).

https://mcp.popnx.com/mcp

Claude Code

  1. Paste the command below in a terminal (--scope user makes it available in every project).
  2. Restart Claude Code and run /mcp: popnx should show as connected.
claude mcp add --transport http --scope user popnx https://mcp.popnx.com/mcp

Claude (Cowork, Desktop and web)

  1. Go to Settings → Connectors → Add custom connector.
  2. Name it PopNx MCP and paste the URL below. No other settings.
  3. In a chat, open the tools menu and turn on PopNx MCP. Some organisation plans need an admin to add it first.
https://mcp.popnx.com/mcp

ChatGPT

  1. Go to Settings → Apps & Connectors → Advanced settings and turn on Developer mode (some plans only).
  2. Click Create, name it PopNx MCP, paste the URL below and choose No authentication.
  3. In a new chat, turn on Developer mode and pick PopNx MCP.
https://mcp.popnx.com/mcp

Codex

  1. Paste the command below in a terminal (or add [mcp_servers.popnx] with url = "https://mcp.popnx.com/mcp" to ~/.codex/config.toml).
  2. Start Codex again and run /mcp: popnx should be listed.
codex mcp add popnx --url https://mcp.popnx.com/mcp

Cursor and VS Code

  1. Cursor: paste the JSON below into ~/.cursor/mcp.json.
  2. VS Code: run "MCP: Add Server", choose HTTP and paste the URL, or put it in .vscode/mcp.json under "servers" instead of "mcpServers".
{
  "mcpServers": {
    "popnx": {
      "url": "https://mcp.popnx.com/mcp"
    }
  }
}

What your AI can do

Every tool is read-only. Nothing on your computer or in your accounts is changed.

Search MCP servers by task

Any language. Returns usage level, downloads, stars and a plain summary.

Details and comparison

Publisher, license, values you must supply, basic checks, tool list and alternatives in the same category.

Install steps per app

Commands or configs for Claude Code, Claude, ChatGPT, Codex, Cursor and VS Code, with key fields left for you to fill.

Read the README

The publisher's GitHub guide with scripts and key-like strings removed.

Find and read skills

Search Agent Skills (SKILL.md) in the Anthropic and OpenAI libraries and in each server's repo, so your AI can learn a workflow first.

Try asking

  1. Use PopNx to find MCP servers that answer customer chats on LINE and compare the 3 most used.
  2. Find the Notion MCP made by Notion itself and show me how to install it in Codex.
  3. Find a skill for making slides, read it and summarise the steps in 5 points.
  4. My shop sells on Shopify and I want AI to check sales every morning. Which MCP should I connect and what do I need?

Safety

We do not keep what your AI asks, there are no accounts, and nothing about you is sent anywhere.

Names, descriptions, READMEs and skill files are written by each publisher. We label them as data that your AI must not obey; entries with instruction-like text are hidden and flagged.

Install commands run other people's code on your computer, so let your AI ask you before installing anything. Our checks are basic, not a security guarantee.
