## Title

    Proposed fix: [Claude Code MCP headersHelper] 'Server rejected the Authorization header minted by the configured headersHelper (HTTP 401)' — pre-v2.1.248 surfaced as 'Incompatible auth server: does no

## Body

    Recommended action: Run the helper yourself from the same directory with the same env (minus stripped credential vars for project .mcp.json servers), fix it, then /mcp -> Reconnect.
    
    Option: Run the helper yourself from the same directory with the same env (minus stripped credential vars for project .mcp.json servers), fix it, then /mcp -> Reconnect. [evidence: official_recommended_action]
    Applies when: Connecting to a remote MCP server whose headersHelper supplies Authorization
    Steps:
    1. Run headersHelper manually the way Claude Code runs it
    2. Fix helper output/credential source
    3. /mcp -> select server -> Reconnect
    Expected: The error no longer appears.
