The only OAuth surface Justt exposes is the MCP endpoint on its WordPress host, whose RFC 8414 metadata declares a single scope. That is what is recorded here; it is discovered by probe, not documented by Justt, and it does not govern the chargeback API. docs: null schemes: - name: mcp-oauth source: well-known/justt-oauth-authorization-server.json issuer: https://justt.ai flows: - flow: authorizationCode authorizationUrl: https://justt.ai/oauth/authorize tokenUrl: https://justt.ai/oauth/token revocationUrl: https://justt.ai/oauth/revoke pkce: S256 token_endpoint_auth_methods: [none] scopes: - scope: mcp description: >- The single scope advertised by Justt's authorization-server metadata, and the only scope named by the protected-resource document for https://justt.ai/wp-json/mcp/mcp-oauth-server.
