Signing in with GitHub also connects GitHub to your account.
What you hold
Signing in gives you what your organization holds on the product you signed in to. A product lists only what your access reaches. If your account holds nothing on that product, sign-in is refused with:<resource> is the product’s address, such as https://harwell.metaphi.ai/mcp/. Request access, then sign in again.
After your organization’s access changes, sign in again so your client’s token carries it.
