How mcpauth compares to general-purpose identity platforms
Descope, Auth0, Stytch, and WorkOS are strong, well-funded platforms built for enterprise identity — SSO, SCIM, multi-tenant user management, the works. mcpauth isn't trying to replace any of them. It's a narrow tool that does one thing: OAuth 2.1 with Dynamic Client Registration (RFC 7591), specifically for an MCP server, with transparent self-serve pricing and no sales call required to get a client ID.

|---|---|---|---|---|---|
| Self-serve signup | Yes | Yes | Yes | Yes | Yes |
| Published MCP-specific pricing | Yes — $0 / $29/mo | Plans from $249/mo | Bundled in platform pricing | Bundled in platform pricing | Bundled in platform pricing |
| DCR / RFC 7591 support | Native, out of the box | Yes | Part of Auth for GenAI | Via Connected Apps | Via AuthKit |
| Free tier | 1 project, 1,000 monthly active tokens | No published free tier | Startup program: free B2B tier, 100k MAU | Free tier, 10,000 MAU | No published free tier |
| Typical setup time | Minutes — one middleware call | Hours to days | Hours to days | Hours to days | Hours to days |
| Requires adopting a broader SSO/SCIM platform | No | No, but built for it | Effectively yes | Effectively yes | Effectively yes |
Setup time and platform-adoption rows reflect the typical integration path for each product's primary offering, not a claim about what's technically possible. See each comparison page for specifics and sources.
Competitor by competitor
mcpauth vs. Descope
Descope's Agentic Identity Hub covers OAuth for MCP servers as part of a broader agentic-identity platform, with plans starting at $249/mo. It's a strong fit if you're already standardizing on Descope for agent and non-human identity beyond just an MCP server.
mcpauth vs. Auth0
Auth0 offers a startup program with a free B2B tier (up to 100,000 MAU), and MCP support lives inside its broader "Auth for GenAI" umbrella. It's the right call if you want one identity platform across your whole product, not just an MCP server.
mcpauth vs. Stytch
Stytch has a generous free tier (10,000 MAU) and Connected Apps support for MCP-style OAuth flows, but it assumes you adopt Stytch as your full CIAM — sign-up, sessions, and user management included.
mcpauth vs. WorkOS
WorkOS AuthKit bundles MCP OAuth support inside a broader enterprise IAM product built for SSO and directory sync. It's built for teams selling into enterprises that already expect SAML/SCIM, not for a standalone MCP server.
mcpauth vs. Static API keys
The most common status quo: no OAuth server at all, just a bare API key or PAT checked on every request. It's the fastest thing to ship and the reason 40% of publicly exposed MCP servers have no real auth today.
mcpauth vs. @mcpauth/auth (self-hosted)
An open-source, self-hostable OAuth server for MCP servers from a different team (github.com/mcpauth) — not affiliated with us, and confusingly close in name. The comparison here is a different axis than the rest of this page: hosted (us) vs. self-hosted open-source (them), not narrow tool vs. broad platform.
mcpauth vs. mcp-auth.dev
A third, also unaffiliated and also confusingly named project — by Silverhand, makers of the Logto identity platform. mcp-auth.dev isn't a server at all; it's a library that bridges your MCP server to a third-party OAuth provider you already run (Auth0, WorkOS, Logto, etc.). mcpauth needs no separate provider — the authorization server is the product.
When to use a full CIAM platform instead
If what you actually need is enterprise SSO, SCIM provisioning, multi-tenant organization management, or audit logging across your whole product — not just OAuth for an MCP server — Descope, Auth0, Stytch, and WorkOS are the right tools for that job. They do far more than mcpauth does, and that breadth is the point. mcpauth is deliberately narrow: it exists for teams who need spec-correct OAuth 2.1 and Dynamic Client Registration in front of an MCP server today, without adopting a full identity platform to get it.
