Polar MCP server (production)

For partner integrations acting on behalf of Polar users, create an OAuth client in User Settings → OAuth. Provide an application name, client type, https:// redirect URI(s) (or http://localhost for local development), requested scopes, and homepage URL. After creation, copy the client_id and client_secret (public clients may omit a secret and must use PKCE). Use this client to run the authorization-code flow against Polar’s OpenID Connect endpoints discovered from OpenID Configuration.
