Adds region parameter throughout the MCP client configuration flow. When region is 'eu', appends `?region=eu` to the MCP URL so the server can route OAuth to the correct authorization server. Co-Authored-By: Claude Opus 4.5 <noreply@anthropic.com>
Adds a prompt asking users how they want to authenticate: - API Key: existing flow, creates personal API key - OAuth (Beta): skips API key, lets MCP handle OAuth on first use This enables JIT provisioning for new users (e.g., Replit integration).

Removes the user prompt asking to choose between API Key and OAuth authentication. OAuth is now the default authentication method for MCP server setup, streamlining the wizard flow and reducing user friction. This addresses feedback in PR #220 to make OAuth the default since it's proven reliable. Co-Authored-By: Claude Sonnet 4.5 <noreply@anthropic.com>
Removes the authentication method prompt and defaults to OAuth for MCP setup. Users no longer need to create a Personal API key upfront - authentication happens when they first use the MCP. Co-Authored-By: Claude Opus 4.5 <noreply@anthropic.com>
