System Documentation

What problem does it solve?

CLI applications often struggle to securely authenticate users against external providers without exposing credentials or compromising tokens. This skill provides a PKCE-based OAuth 2.1 flow with secure token storage and automatic refresh, suitable for CLI tools and SDKs.

Core Features & Use Cases

  • PKCE with S256 is mandatory for public clients.
  • Secure token storage using system keyring with file-based fallback.
  • Automatic token refresh with a 60-second expiration buffer.
  • Provider templates to easily add new OAuth providers.
  • CLI/SDK integration and debugging guidance.

Quick Start

Authenticate a provider (for example, GitHub) by invoking the OAuth flow via the CLI (for example, context-harness mcp auth github) and complete the browser-based login. Tokens are stored securely and refreshed automatically.
