OAuth Clients

Register OAuth client (anonymous DCR)

Register a public OAuth client anonymously (RFC 7591 subset, §4.2).

Returns 201 with the new client_id, or 200 with the existing row's client_id on an exact (software_id + redirect-URI set) dedupe match (D8). No client_secret is ever issued here and no registration_access_token is returned (D12). New rows await admin approval unless the deployment auto-approves registrations (D9). The server.mcp.oauth.enabled gate lives on the route class — a disabled door 404s before this handler, its body validation, or the rate limiter ever run.
