This comparison is part of our MCP comparisons, within The MCP Guide. Facts are checked against each vendor's own documentation and pricing pages on the date shown.
Pick Stytch if you want pay-as-you-go pricing with 10,000 free users and AI agents, and your MCP server only needs sign-in and consent. Pick Descope if you want a broader agent identity platform with CIMD as the recommended registration method, a vault for downstream tokens and per-tool scopes. Both make your app an OAuth provider that MCP clients can sign in to.
Checked against: Stytch's MCP server guide and Descope's Agentic Identity Hub docs on 28 October 2026. eSEOspace did not test either product.
One ownership note first. Stytch's own announcement of 30 October 2025 says "Stytch is now a part of Twilio." It promised "no immediate changes" to agreements, rates, SDKs or credentials. Descope is an independent identity vendor.
Key Takeaways
- Stytch treats MCP clients as "a type of Connected App," with Stytch as the OAuth authorization server and your app hosting the consent screen.
- Descope calls its Agentic Identity Hub a "control plane for AI agent identity," covering MCP servers, clients, token vaults, gateways and policies.
- Descope recommends Client ID Metadata Documents (CIMD) for new MCP servers; Stytch offers CIMD as a beta and DCR as opt-in.
- Stytch's free allowance covers 10,000 monthly active users and AI agents; Descope's Free Forever plan includes 7,500 MAUs and 2,000 MCP consents (MACs).
- Descope lists FedRAMP High authorization among its certifications; Stytch's compliance documents sit in the Twilio Trust Center.
At a glance

| DCR | Opt-in in the dashboard | Supported, mainly for backward compatibility |
| Consent screen | Hosted in your app with Stytch components | Not detailed on the pages we opened |
| Downstream token vault | Not documented on the MCP guide | Connections ("vault OAuth tokens and API keys") |
| Gateway | Not documented | Agent Gateway, early access |
| Enterprise IdP access | Not documented on the MCP guide | Cross App Access (XAA) guide |
| Example frameworks | Express, Next.js, FastMCP, Hono | Not confirmed on the hub page |

| Paid entry | Pay as you go | Pro from $249/mo, billed annually |
Where Stytch is stronger
Pay-as-you-go with a wide free band. Stytch's pricing page lists an always-free allowance of 10,000 monthly active users and AI agents, unlimited organizations, 5 SSO or SCIM connections and 1,000 machine-to-machine tokens. The FAQ says there are no hard caps or pricing cliffs.
Consent in your own app. In Stytch's MCP guide, your main application hosts the IdentityProvider component (or B2BIdentityProvider) that shows the consent step. Members must be logged in first. If brand control over the consent screen matters, this design gives it to you.
Framework examples. The guide includes examples for Express, Next.js (with Vercel's MCP adapter), FastMCP for Python and Hono, and links a Cloudflare guide.
Clear first-party vs third-party rules. Stytch's client types page says third-party apps always need consent: "End-user consent is required for all interactions." Clients created through DCR are third-party public clients.
Where Descope is stronger
CIMD-first registration. Descope's registration methods page says: "For new MCP server deployments, Client ID Metadata Documents (CIMD) is the recommended approach." It keeps DCR "primarily for backwards compatibility with earlier versions of the MCP authorization spec." That matches the 2026-07-28 spec, which deprecated DCR. Stytch still labels CIMD "(Beta)" and warns that "changes in validation logic may occur before final adoption."
Tighter registration controls. Descope says DCR scope requests "must be from the MCP server's approved scopes list," and redirect URIs can be limited to approved patterns, such as only Cursor's callback.
Broader agent identity. The hub docs list per-tool scopes and tenant isolation for MCP servers, Connections that vault downstream OAuth tokens and API keys, policies "evaluated at token issuance and exchange," and an Agent Gateway in early access.
Enterprise-managed authorization. Descope has a guide that uses Cross App Access (XAA) to issue tokens for agents. See enterprise-managed authorization.
Pricing
Prices from each vendor's pricing page on 28 October 2026.
Stytch (pricing):
- Pay as you go: starts at $0 per month, B2B SaaS and Consumer variants.
- Always free: 10,000 MAUs and AI agents, unlimited organizations, 5 SSO or SCIM connections, 1,000 M2M tokens.
- Extra SSO or SCIM connections: $125 each. Extra members, agents and M2M tokens are billed, but the page does not list the rate.
- Enterprise: custom, with a 99.99% uptime SLA.
- No separate Connected Apps or MCP line item.
Descope (pricing):
- Free Forever: $0, 7,500 MAUs, 2,000 MACs, 2,000 MATKs. No overages; you upgrade to go past the limits.
- Pro: from $249 per month, billed annually, 10,000 MAUs and 5,000 MACs.
- Growth: from $799 per month, billed annually, 25,000 MAUs and 10,000 MACs.
- Enterprise: custom.
Descope counts a MAC when "a unique user consents to any scope for a specific resource at least once in a month," and says it "only charges for active consents." MATKs count outbound tokens fetched and used.
Security and admin controls
Stytch. Its compliance page says Stytch documents, "including our SOC 2 report, ISO 27001 certification, CAIQ, PCI-DSS, and more," are in the Twilio Trust Center. For CIMD clients, Stytch notes manual edits "may be overwritten" when it refreshes metadata.
Descope. Its security and compliance page says Descope is "SOC 2 Type 2 compliant and certified," "ISO 27001 certified," "FedRAMP High Authorized," "CSA STAR Level 2 certified" and "PCI DSS certified," and that it is HIPAA and GDPR compliant.
Your server's job either way. Validate every token's issuer, audience, expiry and scopes, and do not forward client tokens to upstream APIs. See MCP token passthrough and MCP OAuth misconfiguration.
Which to choose
Pick Stytch if:
- You want to host the consent screen in your own app.
- Your user count is under 10,000 and you want to pay nothing to start.
- You build with Express, Next.js, Hono or FastMCP and want ready examples.
Pick Descope if:
- You want CIMD as the default registration path today.
- Your server needs a vault for downstream tokens, per-tool scopes or a gateway.
- You sell to government or regulated buyers who ask about FedRAMP.
Next step
Map your server's auth needs first: who signs in, which clients connect and which downstream APIs it calls. eSEOspace sets this up through our MCP development service. Compare WorkOS vs Auth0 or browse all MCP comparisons.
Frequently asked questions
Is Stytch still independent?
No. Stytch announced on 30 October 2025 that it "is now a part of Twilio." The post said there were no immediate changes to agreements, rates, SDKs or credentials. Its compliance documents are now in the Twilio Trust Center.
Does Stytch support CIMD?
Yes, as a beta. Stytch's client types page labels CIMD "(Beta)" and says validation logic may change because CIMD is still an IETF draft. DCR is available as an opt-in. The MCP server guide itself does not mention CIMD.
What is a MAC on Descope's pricing?
A monthly active consent. Descope counts one when a unique user consents to any scope for a specific resource at least once in a month. Repeat consents by the same user to the same scopes and server are not charged again.
Which is cheaper for a small MCP server?
For a few thousand users, both can start at $0. Stytch's free band is larger at 10,000 users and agents. Descope Free has 7,500 MAUs and 2,000 MCP consents, and you must upgrade, from $249 per month billed annually, to go past them.
