Descope
Descope is notable for being one of the few auth providers that explicitly targets AI agent developers as a primary audience, not an afterthought. The product includes native support for MCP (Model Context Protocol) server authorization, human-in-the-loop approval flows, and async authorization — all designed with agentic workflows in mind.
The AI/agent SDK covers token delegation, scoped access for agents acting on behalf of users, and fine-grained authorization rules. MCP support is the standout differentiator — if you're building or consuming MCP servers, Descope has native tooling for it.
The tradeoff is maturity. Descope is newer than Auth0 or Clerk, and the ecosystem (community resources, third-party integrations, StackOverflow coverage) reflects that. For greenfield agent projects, that's less of a concern; for teams that need battle-tested infrastructure, it's worth weighing.
Agent-specific features:
- Native MCP server authorization
- Human-in-the-loop approval workflows
- Async authorization for non-blocking agent approval requests
- Token delegation for downstream service access
- FGA for fine-grained permission modeling
