OAuth client identities

Names reported by a client describe its own registration. The client ID and issuer identify the OAuth client.

Client ID: https://v0.app/api/chat/integrations/oauth/client-metadata.json
Issuer: Not recorded
Registration method: CIMD metadata URL
Reported name: v0

MCP protocol version history

Newest protocol versions first, then most recently seen. Repeated client releases and version outcomes are counted together. Protocol acceptance and request outcomes are shown separately; an unsupported method does not reject an accepted version. A counter-offer or discovery response does not prove the client used that version. New observations from token-linked sessions are associated with the exact OAuth identity; older observations without an identity link remain on the global protocol history.

No protocol observations are linked to this OAuth identity yet. Historical observations without an identity link remain on the global protocol history.

No protocol versions recorded yet. Reconnect the MCP client and make a request to capture its version.
