Descope for AI Agent Security: Features, Pricing, and Alternatives — WorkOS

Descope for AI Agent Security: Features, Pricing, and Alternatives

Descope launched its Agentic Identity Hub in April 2025, positioning itself as a developer-focused external IAM platform for agent authentication and authorization. In this article, we’ll examine Descope’s approach to agentic identity, explore their key features and pricing, and compare their offering to production-ready alternatives like WorkOS—especially for B2B SaaS teams.

As AI agents evolve from simple chatbots to autonomous systems managing sensitive enterprise data, authentication and identity management have become critical security challenges.

What is Descope?

Descope is a no/low-code external identity and authentication platform. It originally focused on customer IAM (CIAM) and B2B auth, and has since raised a total of $88M in seed funding to expand into “agentic identity” for AI agents and MCP ecosystems.

In April 2025, Descope announced the Agentic Identity Hub, described as an “industry-first platform” to solve authentication and authorization challenges for AI agents, systems, and workflows—including apps that need to become agent-compatible, AI agents that need to connect to external tools, and remote MCP servers that need OAuth-based authorization.

They position the platform at developers building AI and MCP-based systems, and publicly list customers such as Databricks, GoFundMe, Navan, and You.com.

Descope’s traditional auth product is reasonably mature, with SOC 2 Type 2, ISO 27001, HIPAA, GDPR, and CSA STAR certifications/compliance. The agentic identity components, however, are new as of 2025 and still building their enterprise track record.

Key Features and Capabilities

Descope’s Agentic Identity Hub is structured around four main building blocks: Inbound Apps, Outbound Apps, MCP Auth SDKs, and an Agentic Identity Control Plane.

Inbound vs. Outbound Agent Apps

Descope distinguishes between:

Inbound Apps let your application “become its own IdP” using OAuth, so agents can request specific scopes and users/IT admins see consent screens and can revoke access.

Outbound Apps give you 50+ prebuilt integrations so you don’t have to hand-roll scopes, token storage, or refresh logic for every SaaS tool your agent touches. This is legitimately useful if your agents need to call a standard basket of SaaS APIs without your team becoming OAuth experts for each one.

Under the hood, both inbound and outbound paths lean on OAuth 2.x authorization code flows with PKCE for public clients. For MCP, Descope explicitly aligns itself with the MCP authorization spec, which standardizes on OAuth 2.1, protected resource metadata, authorization server metadata, and (optionally) Dynamic Client Registration.

MCP Auth SDKs & APIs

Descope ships MCP Auth SDKs and APIs specifically for remote MCP servers. The goal is the same category as WorkOS AuthKit, just from a different vendor:

They explicitly pitch this as “secure your remote MCP servers with authorization in three lines of code” for developers who don’t want to implement the OAuth 2.1 machinery themselves.

Agentic Identity Control Plane

In August 2025, Descope extended the Hub with an Agentic Identity Control Plane—policy-based governance, auditing, and lifecycle management for AI agents and MCP clients/servers.

The control plane adds:

How Descope Handles Agent Authentication

Descope’s architecture treats AI agents and MCP servers as OAuth clients and protected resources.

For simple cases (one agent, a couple of SaaS tools), you really can wire this up in an afternoon via Descope’s visual flows and SDKs. That’s the genuine strength: quick time-to-demo and DevX.

The trade-offs start to show up in more complex enterprise scenarios:

Descope is actively shipping features in all those directions (SCIM, fine-grained auth, orchestration). But the agentic pieces are very new. The reality today is: Descope is racing to become a unified external IAM + agentic identity platform; WorkOS is a more narrowly focused, long-running enterprise auth platform with a recently added MCP auth story.

Pricing and Plans

Descope currently offers:

Agentic Identity Hub capabilities (Inbound, Outbound, MCP SDKs) are marketed as part of the core platform rather than a separate product line, but it’s clear from their pricing explainers that some advanced features (SCIM, multi-region, FGA, etc.) are gated to Growth/Enterprise tiers.

The key nuance: Descope prices on MAUs and tenants. If you model every AI agent as a separate “user” or if you have lots of machine-to-machine traffic, you need to watch that MAU math carefully—it’s easy to end up in higher tiers quickly.

Descope vs. WorkOS

Descope’s Agentic Identity Hub is a serious attempt to build identity infrastructure for AI agents, apps, and MCP servers. For greenfield AI products where you want one vendor delivering CIAM + B2B auth + agentic identity + MCP auth, Descope is becoming a credible option.

But for B2B SaaS teams, especially those whose revenue depends on enterprise SSO and directory sync, WorkOS still has a much longer and deeper track record.

What Descope Offers

The limitation isn’t that Descope is “toy-grade” or missing SOC2/HIPAA; it clearly isn’t. The limitation is that its agentic capabilities are brand-new, whereas the rest of their platform and many of their customers are still primarily in more traditional CIAM/B2B auth scenarios.

Why WorkOS Is the Enterprise-Ready Choice

WorkOS, by contrast, has been built from the start as a developer-first, B2B SaaS auth platform with:

And critically for this article: WorkOS now ships AuthKit for MCP, which is a spec-compatible OAuth 2.1 authorization server for MCP apps:

That means WorkOS and Descope are actually peers in one very specific area (MCP auth) but WorkOS brings a longer history in enterprise B2B auth and a simpler story if your primary problem is: “I’m a SaaS vendor; I need to integrate with my customers’ IdPs and secure MCP servers and agents at the same time.”

The Right Choice for Most B2B SaaS Teams

For early-stage AI-heavy products where you want a single vendor to cover CIAM, B2B auth, and agentic identity, Descope’s Agentic Identity Hub is worth watching. It has real momentum, smart primitives, and a fast-moving roadmap.

For B2B SaaS teams whose critical path is enterprise deals—SSO, SCIM, audit logs, FGA, and now MCP auth—WorkOS is still the safer, more proven bet:

Descope is aggressively innovating around agentic identity and has a strong core platform. But its agent-specific capabilities are still in their first year of life.
