SSOJet Adds MCP Authentication, Completing the B2B SaaS Identity Stack

News Provided by ACCESS Newswire2026-09-30

SAN FRANCISCO, CA / ACCESS Newswire / September 30, 2026 /SSOJet today launched MCP Authentication, letting B2B SaaS companies protect their Model Context Protocol (MCP) servers with the same identity system that already handles their customer logins and enterprise SSO. The release completes SSOJet 's move to a full-stack B2B SaaS auth platform spanning authentication, team management, enterprise SSO, machine-to-machine access and MCP.

MCP has quickly become the way SaaS products expose their data and actions to AI assistants and agents in tools like Claude, Cursor and Windsurf. But most MCP servers shipped so far are unauthenticated or sit behind a shared API key, because putting a real login in front of one means standing up an OAuth flow for a single endpoint - work that has little to do with the product the team is trying to ship.

SSOJet 's MCP Authentication makes SSOJet the identity provider behind a customer 's remote MCP server. Developers clone SSOJet 's open-source MCP server template, add their SSOJet client credentials, issuer URL and scopes, and deploy to Cloudflare Workers. Users connecting from an MCP client sign in through SSOJet before any tool is callable, using the same sign-in methods the SaaS product already offers - passwordless, passkeys, MFA, social login, or the customer 's own enterprise SSO provider. No tools are exposed until that login completes.

"Every team shipping an MCP server hits the same wall: you 've already got login working in your product, and then MCP asks you to build a whole OAuth flow again for one endpoint, " said Govardhan Sisodia, Developer Advocate at SSOJet. "Most people either skip it and ship a static key, or lose a sprint to it. Clone the template, drop in your SSOJet credentials, deploy. Your MCP server uses the login your users already have. "

One Platform Across the B2B Identity Lifecycle

MCP Authentication joins the capabilities SSOJet already provides, covering how B2B SaaS products actually grow:

Authentication - Onboard end users with passwordless, passkey, MFA and social sign-in
Team Management - Let customers invite and manage their own team members inside the product
SSO Integration - Connect enterprise customers ' workforce identity providers over SAML and OIDC, with SCIM and JIT provisioning
M2M Authentication - Secure service-to-service and API access
MCP Authentication - Require a real user login before an MCP client can reach a server 's tools

Because all of it runs on one tenant and role model, a SaaS company adding MCP does not re-model its permissions or operate a second identity system alongside the first.

MCP Authentication is available now to all SSOJet customers. The setup guide and open-source server template are at SSOJet MCP remote server.
