  description: >-
    Scalekit is the authentication platform for B2B SaaS and AI agents. The
    REST API provides programmatic access to enterprise Single Sign-On (SAML /
    OIDC connections), SCIM directory provisioning, organizations, users and
    memberships, organization roles, machine-to-machine (M2M) authentication,
    and agent / MCP connected accounts and tool execution. The API base URL is
    per-environment; access tokens are obtained via the OAuth 2.0 client
    credentials grant and passed as Bearer tokens.
