Okta vs WorkOS for MCP Server Auth: What It Actually Costs in 2026

You typed "okta vs workos mcp server enterprise authentication cost" into a search bar because you're building an MCP server, an enterprise customer asked how you secure it, and you need a number. The pages that came back gave you a lot of numbers — $125 per SSO connection, $6 per user per month, a $1,500 annual minimum — but almost none of them are the number you actually need. Most of those comparisons are pricing enterprise SSO or workforce identity, which is a related but different job. And at least two of them are quietly comparing products that don't do the same thing.

Here's the part every page-1 result glosses over: Okta does not sell a drop-in OAuth authorization server for your MCP server with published pricing. When people say "Okta MCP server," they usually mean Okta's open-source MCP server — which points an agent at Okta's admin API — not a thing that puts auth in front of the MCP server you're shipping. Those are opposite directions. If you don't untangle that first, every cost comparison you read is apples-to-oranges, and you'll walk into a sales call anchored to the wrong price.

So before any table, let's separate the three products that are hiding inside your one query.

What you're actually comparing (and why the query is a trap)

There are three distinct things people mean when they ask about "MCP server auth cost," and the SERP blends all three:

1. An OAuth 2.1 authorization server for your MCP server. This is the thing the MCP spec actually mandates — PKCE, Protected Resource Metadata (RFC 9728), Resource Indicators (RFC 8707), and either DCR or CIMD for client registration. This is what makes your MCP server safe to expose on the public internet. WorkOS AuthKit does this directly. Okta's answer here is Auth0.

2. Enterprise SSO/SCIM for the app the MCP server belongs to. When a customer's IT team wants to log their whole org in via Okta or Entra ID and provision users over SCIM, that's a separate capability. This is the $125-per-connection line item everyone quotes. It's real, but it's not MCP-specific — you'd pay it whether or not you shipped an MCP server.

3. Okta's agentic-identity products — Cross App Access (XAA), Identity Security Posture Management (ISPM), Auth for GenAI. These govern agent identities inside an enterprise that already runs Okta. They solve agent-to-app delegation and non-human-identity discovery, not "make my public MCP endpoint spec-compliant." They're sold through enterprise contracts and early-access programs, not a pricing page.

Here's the mapping the other comparisons never lay out cleanly:

Notice the confusion baked into the query: Okta owns Auth0, so "Okta for a SaaS vendor's own login" really means Auth0. Okta Workforce Identity — the one with the $6/user/month, $1,500-annual-minimum pricing everyone quotes — is what your customers run for their own employees. It is not what you, the SaaS vendor, buy to accept those logins or to secure your MCP server. If you shortlist "Okta" and "WorkOS" as if they're the same shape of product, you've already made a mistake the vendors are happy to let you make.

What Okta's MCP story actually costs

Let's be concrete about where the dollars go if you go the Okta/Auth0 route.

The open-source Okta MCP server is free — it's a published server (shipped September 2025) that connects an agent to Okta's management APIs so it can automate user, group, and log operations. If your use case is "let an internal agent administer our Okta tenant," this is genuinely useful and costs nothing beyond your existing Okta bill. It is not, however, an authorization server for a customer-facing MCP product.

To put spec-compliant OAuth in front of your MCP server, you're on Auth0. Auth0's B2B tier starts at $150/month for 500 monthly active users and includes only 3 enterprise SSO connections, with a hard cap of 30 self-serve connections total (Auth0 pricing, as reported mid-2026). The moment you exceed those limits — more MAU, more enterprise connections, or you need real support — you're into B2B Professional or Enterprise, which is sales-quoted. The Reddit data point that keeps surfacing ("Auth0 wants $800/month") is roughly what the SSO-capable tier costs a small B2B shop. At real enterprise scale it's a negotiated contract, and you will not get a number without a call.

Auth0's MCP/DCR support is the sharper concern. Traditional Okta and Entra OAuth famously don't support Dynamic Client Registration; Auth0 has been catching up on the MCP-specific surface, but you should validate DCR, RFC 9728 metadata discovery, and RFC 8707 resource indicators against your MCP client matrix (Claude, Cursor, ChatGPT, Windsurf) before you commit, not after. Spec-compliance-on-paper and spec-compliance-your-clients-actually-negotiate are different things.

The honest summary: Okta's agentic pitch — XAA for cross-app delegation, ISPM for non-human-identity discovery — is real and genuinely valuable if you're already an Okta enterprise. It folds agent identities into governance workflows your security team already knows. But it imports the enterprise sales motion, the annual contract, and the "talk to us" pricing along with it. For a team whose whole ask is "make my MCP server safe to expose," it's a lot of platform to buy.

What WorkOS costs for the same job

WorkOS is the cleaner fit for the literal MCP-auth job, and its pricing is public, which is half the reason it ranks for this query.

AuthKit — including its OAuth 2.1 authorization server that fronts MCP servers — is free up to 1 million monthly active users (verify the current threshold on the pricing page, but this has been the standing offer). AuthKit works with the official MCP SDKs and can act as the authorization server the spec demands: DCR, PKCE, discovery endpoints out of the box. If your MCP server is early and you have no enterprise-SSO customers yet, your MCP auth bill can genuinely be $0.

You start paying when customers demand enterprise SSO or SCIM. WorkOS bills those on a graduated per-connection scale:

Directory Sync (SCIM) is priced identically, so a customer that needs both SSO and provisioning is effectively double the per-connection rate. This is where the scary aggregate numbers come from: at 50 enterprise customers needing both SSO and SCIM, the monthly bill lands in the $8,250–$11,250 range (per the shared-scenario math Scalekit and Security Boulevard both ran in 2026). That's real, and it's the strongest argument for the overlay brokers — Scalekit and SSOJet both undercut WorkOS at roughly $49.50/connection with unlimited MAU. If per-connection cost at 50+ enterprise customers is your dominant line item, price those two.

But note what this means for the MCP question specifically: the expensive part of WorkOS is not the MCP auth. It's the enterprise SSO you'd be buying regardless. The MCP authorization server itself rides on the free AuthKit tier for most teams.

A side-by-side at MCP-server scale

Take a realistic mid-stage scenario: a B2B SaaS shipping an MCP server, ~5,000 MAU, and 10 enterprise customers who want SAML SSO (no SCIM yet).

The takeaway isn't "WorkOS always wins." It's that for the specific job of securing an MCP server plus a handful of enterprise SSO customers, WorkOS gives you a self-serve number today and a $0 starting point, while Okta gives you a governance platform and a sales calendar. Different products for different buyers.

The DCR pricing trap nobody mentions

Here's the gap none of the ranking pages address, and it's the one that actually bites at MCP scale.

MCP clients register dynamically. Every new agent — every Claude instance, every Cursor install, every ChatGPT connector — can self-register with your authorization server via DCR. That means a single human user might generate dozens of registered OAuth clients over time, and a popular MCP server could accumulate thousands.

The obvious fear: am I billed per registered client? For WorkOS and Auth0's core plans, no — they bill on MAU or SSO connections, not per OAuth client, so DCR-registered clients don't each carry a line-item fee. Good.

The non-obvious trap: Auth0's machine-to-machine (M2M) token pricing is metered separately. If your agent architecture leans on client-credentials grants (agent-as-service-account rather than agent-acting-on-behalf-of-user), you can quietly rack up M2M charges that never show up in a per-connection comparison. Historically this M2M metering has been one of the sharpest edges in Auth0 bills. Before you pick a provider, map your actual grant types — are your agents doing authorization-code-with-PKCE on behalf of a user, or client-credentials as their own identity? — because the second path is priced on an axis the SSO comparisons ignore entirely.

The second DCR pitfall is operational, not financial: unbounded dynamic registration is an abuse surface. An open DCR endpoint that anyone can hit will accumulate junk clients and can be used to probe your server. Whatever provider you pick, confirm it supports client registration policies, CIMD for trusted clients (the 2025-11-25 spec's preferred path), or software-statement gating — otherwise "free DCR" becomes "free for attackers too."

Common pitfalls

• Anchoring on the $6/user/month Okta number. That's Okta Workforce — your customers' internal IdP cost, not your cost to accept their logins or secure your MCP server. It should not appear in your budget model at all.
• Assuming "Okta MCP server" secures your endpoint. It administers Okta. If you deploy it expecting an authorization server, you've solved the wrong problem.
• Comparing WorkOS's per-connection price to Okta's per-seat price. Different units. One scales with your enterprise-customer count, the other with an employee headcount you don't pay for. The comparison is meaningless without normalizing to your scenario.
• Forgetting SCIM roughly doubles WorkOS's per-connection cost. Enterprise buyers ask for provisioning during security review more often than teams expect. Budget for it up front.
• Not testing DCR against your real client matrix. "Spec-compliant" on a marketing page and "Claude Desktop successfully completes the OAuth dance against your server" are different claims. Test the second one.
• Missing Auth0's M2M metering if your agents authenticate as themselves rather than on behalf of a user.

Where this leaves you

For most teams reading this, the decision is simpler than the SERP makes it look. If you're a B2B SaaS shipping an MCP server and you want spec-compliant OAuth plus enterprise SSO with a number you can see today, WorkOS AuthKit is the shortest path and starts at free. If your enterprise-customer count pushes your per-connection bill past a few thousand a month, price the overlay brokers (Scalekit, SSOJet) against it before renewing. And if you're inside an organization that already runs Okta and needs agent identities governed in the same plane as everything else, Okta's XAA-and-ISPM story is worth the sales call — but buy it as governance infrastructure, not as MCP plumbing.

The unresolved tension worth watching: the MCP spec is still moving (CIMD landed in the 2025-11-25 update and shifts the registration model away from DCR), and Okta's agentic products are early-access, not GA-with-pricing. In six months the honest answer might change. If you're deciding today, decide on published pricing and tested spec compliance — not on which logo your security reviewer recognizes.
