The only machine-readable auth description it serves is RFC 8414 OAuth Authorization Server Metadata on getzipline.com, which governs its MCP endpoint. Access to the Zipline retail operations product itself is via customer SSO on a per-tenant subdomain and is not publicly documented. schemes: - key: oauth2_mcp type: oauth2 applies_to: https://getzipline.com/wp-json/mcp/mcp-oauth-server flows: authorizationCode: authorizationUrl: https://getzipline.com/oauth/authorize tokenUrl: https://getzipline.com/oauth/token refreshUrl: https://getzipline.com/oauth/token scopes: mcp: Access the Zipline MCP server pkce_required: true pkce_methods: - S256 response_types_supported: - code grant_types_supported: - authorization_code - refresh_token token_endpoint_auth_methods_supported: - none bearer_methods_supported: - header revocation_endpoint: https://getzipline.com/oauth/revoke client_registration: >- client_id_metadata_document_supported = true — clients identify themselves by a URL-addressable client ID metadata document rather than pre-registering. authorization_response_iss_parameter_supported: true notes: >- Public client profile: token_endpoint_auth_methods_supported is ["none"], so no client secret is used; PKCE S256 is the protection.
