MCP Auth Node.js SDK

The `mcp-auth` library provides plug-and-play authentication and authorization solutions specifically for Model Context Protocol (MCP) servers in Node.js environments. It implements the OAuth 2.1 and OpenID Connect standards as required by the MCP specification, aiming to simplify the integration of MCP servers with compliant identity providers. Currently at version 0.2.0, the project is under active development with frequent releases (e.g., from v0.1.0 to v0.2.0 in a short period), indicating continuous feature additions and refinements. Key differentiators include its strict adherence to MCP authorization requirements, a focus on reducing boilerplate for OAuth/OIDC implementation, and direct support for `express` applications, providing a streamlined developer experience for securing MCP resources. It is provider-agnostic and offers tools for checking provider compliance.
