Overview

Description from the maker (original English)

Ping-only MCP origin for claude.ai, Desktop, Cursor, and Grok Connectors.

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.

Install

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

Before you install

  • Basic checks: 0 of 1 passed
  • Runs on the maker’s server: what you ask it goes through their server.
  • The registry lists no key to fill in.

{
  "mcpServers": {
    "oauth-connect": {
      "url": "https://mcp.gfbytes.com/mcp"
    }
  }
}

Your browser asks to open the app, then the app shows the settings and asks you to confirm. Key values are left empty for you to fill in.

Open in VS Code

Or copy the settings yourself

Paste into .vscode/mcp.json in your project

{
  "servers": {
    "oauth-connect": {
      "type": "http",
      "url": "https://mcp.gfbytes.com/mcp"
    }
  }

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
  4. If it asks you to sign in, sign in with the maker

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.

What it can do

Common questions

Is MCP OAuth Connect safe?

It passed 0 of 1 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 (0.2.0) reached the registry 2 months 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: Spec Driven Development, Remote Desktop Commander, SuperCollider

MCP OAuth Connect

Free checker for when an MCP remote answers curl but dies in Claude / Cursor / Desktop / Grok Connectors.

Part of GFB's lab surface. Founder / peer identity: gregfredabytes.com · essay · what I run

What this is not

  • Not a hosted MCP product. https://mcp.gfbytes.com is a ping-only reference server.
  • Not a completed handshake. The checker reads discovery metadata. It does not do DCR, mint a token, or call tools/list. A fail is a scoping signal, not a dead end.
  • Not the paid attach lab. Four-client attempt + written path lives on the studio product page.

Paste only the URL in a Connectors UI — no API key.

Clone / run

Stdlib Python ≥3.10. No install for the checker:

git clone https://github.com/GFB2026/mcp-oauth-connect.git

cd mcp-oauth-connect python skills/mcp-oauth-connect/scripts/diagnose.py https://mcp.gfbytes.com

Exit 0 if connector-critical checks pass; 1 otherwise. JSON report on stdout.

Looks for a proper login challenge (not a bare 200 from curl), a registration endpoint, PKCE S256, and RFC 9728 protected-resource metadata.

Tests:

python -m pip install "pytest>=8"

python -m pytest

For AI assistants / contributors

Edit lanes and hard stops: .github/copilot-instructions.md. Verify with python -m pytest (install pytest>=8; this tree is flat — no pip install -e).

Plugin install (optional)

Claude Code:

/plugin marketplace add GFB2026/mcp-oauth-connect

/plugin install mcp-oauth-connect@mcp-oauth-connect

Grok Build:

grok plugin marketplace add GFB2026/mcp-oauth-connect

grok plugin install mcp-oauth-connect --trust

Then run the same diagnose.py path as above.
