Library Introduction
SCIM Server is a comprehensive Rust library that implements the SCIM 2.0 (System for Cross-domain Identity Management) protocol—the industry standard for user provisioning. Instead of building custom user management APIs from scratch (which typically takes 3-6 developer months), SCIM Server provides a type-safe, high-performance foundation that gets you from zero to enterprise-ready user provisioning in weeks, not months.
What is SCIM Server?
SCIM Server is a Rust library that provides all the essential components for building SCIM 2.0-compliant systems. Instead of implementing SCIM from scratch, you get proven building blocks that handle the complex parts while letting you focus on your application logic.
The library uses the SCIM 2.0 protocol as a framework to standardize identity data validation and processing. You compose the components you need—from simple single-tenant systems to complex multi-tenant platforms with custom schemas and AI integration.
