Common questions

Is MCP OAuth Connect safe?

It passed 1 of 4 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 2 months ago, and the latest version (0.2.0) reached the registry 3 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 on the web (full MCP on Business and above; Pro read-only).

MCP OAuth Connect

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

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.
