Descope authentication provider for FastMCP.

This module provides DescopeProvider - a complete authentication solution that integrates with Descope's OAuth 2.1 and OpenID Connect services, supporting Dynamic Client Registration (DCR) for seamless MCP client authentication.

Classes

DescopeProvider <sup><a href="https://github.com/PrefectHQ/fastmcp/blob/main/fastmcp_slim/fastmcp/server/auth/providers/descope.py#L79" target="_blank"><Icon icon="github" style="width: 14px; height: 14px;" /></a></sup>

Descope metadata provider for Dynamic Client Registration (DCR).

The provider accepts either a resource-specific Descope MCP Server URL such as /v1/apps/agentic/P.../M.../.well-known/openid-configuration or a project-level inbound app URL such as /v1/apps/P.../.well-known/openid-configuration.

When neither scopes_supported nor required_scopes is provided, advertised scopes are discovered lazily from the OpenID configuration. Use scopes_supported and required_scopes together when the scopes clients should request differ from the scopes enforced during token validation.

See Descope's inbound app documentation for DCR setup instructions.
