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.

MCP OAuth Connect

Find out why four clients won't attach.

The free checker reads metadata. It never finishes a handshake (no DCR, no token, no tools/list). That gap is the product.

For $149 we attempt Claude, Cursor, Desktop, and Grok against your server and send an attach trace — which step worked or died, in which client, with real responses. Failures welcome. If we can't attach and can't say why, you get your money back.

After the trace, fix rounds are quoted separately (typically $600–$1,500): we make it attach; you merge the patch.

Buy / fulfill: https://gfbytes.com/products/mcp-oauth-connect/

On the product page, paste any public HTTPS MCP URL and hit Check — that hits POST /products/diagnose (server-side diagnose.py). Failures are the intended $149 buyers.

Outbound targeting (no auto-send): ph/OUTBOUND_TARGETING.md. Harvest: python skills/mcp-oauth-connect/scripts/harvest_failing.py.

Install (free checker)

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:

python skills/mcp-oauth-connect/scripts/diagnose.py https://your-mcp.example

The checker looks for a proper login challenge on your server (not a 200 from curl), a registration endpoint, and S256. Paste only the URL in the Connectors UI — no API key.

If that check fails, that's what the $149 attach-trace round is for.

Attach trace — $149 once

Checkout asks for your server URL. We attempt all four clients and deliver a written path (401 → PRM → AS → DCR → token → tools/list) per client within two business days. Screenshots are evidence, not the product.

Fix round — quoted

After the trace, we quote a separate fix. Not included in $149. Out of scope for the $149 round without a separate quote: Entra without DCR, custom IdPs, consent-UI flows, hosted tenancy, host tools.
