Summary
userConfigprompt and staticAuthorizationheader/mcpAuthenticate action andclaude mcp login plugin:agentkey:agentkeyRoot cause
Claude Code treats any configured
Authorizationheader as an explicit choice of header authentication. When the interpolated API key is empty, the server returns 401, but Claude Code does not offer or fall back to OAuth because the header is present. Removing the header and itsuserConfigsource restores native MCP OAuth discovery.Impact
The runtime authentication change is limited to the Claude Code plugin path (
.claude-plugin/plugin.json+ root.mcp.json). The Skills CLI/API-key setup path and the Codex, Cursor, Kimi, Gemini, and Antigravity MCP configurations are unchanged.Shared documentation and CI path filters are updated to describe and protect this Claude-specific behavior.
