Trailing slash in `.well-known/oauth-protected-resource` response may violate “Canonical Server URI” requirement

Question

As I understand it, https://your-mcp.com/.well-known/oauth-protected-resource should return:

{
    "resource": "https://your-mcp.com",
    "authorization_servers": [
        "https://your-auth.com"
    ],
    "scopes_supported": [],
    "bearer_methods_supported": [
        "header"
    ]
}

However, it actually returns:

{
    "resource": "https://your-mcp.com/",
    "authorization_servers": [
        "https://your-auth.com/"
    ],
    "scopes_supported": [],
    "bearer_methods_supported": [
        "header"
    ]
}

Note the trailing / in both the resource and authorization_servers values.

According to the MCP spec’s “resource-parameter-implementation” section, I believe this violates the requirement for canonicalization:
https://modelcontextprotocol.io/specification/2025-06-18/basic/authorization#resource-parameter-implementation

Is this a bug, or am I misunderstanding the requirement?

Commencez par localiser l’implémentation de la réponse .well-known/oauth-protected-resource et comparez ses valeurs resource et authorization_servers avec l’exigence de canonicalisation MCP liée. Confirmez le comportement attendu concernant le slash final, puis identifiez ou ajoutez une couverture pour les valeurs de la réponse afin de pouvoir vérifier que le travail est terminé.
