Clerk vs Auth0 for Claude Code
Verdict
Clerk scores 5/5 and Auth0 4/5. Clerk publishes its own Claude Code plugin (from its own marketplace, not Anthropic’s) that bundles skills plus the Clerk MCP server. Auth0’s plugin is in Anthropic’s official marketplace but ships 1 skill and no MCP server, so Claude Code gets guidance but no live access to your tenant.
