error_code: E-MCP-008 · status: retired

What you’re seeing

Nothing: npx vendo doctor cannot print this code anymore. You are reading it from an older run’s output, or a saved report.

Why

This code fired when the deployed copy of /.well-known/mcp-registry-auth did not start with v=MCPv1. Doctor fetched that file from the live origin over HTTP, and it no longer makes any request.

The fix

Nothing to do. Doctor still checks the copy in your repo, and that check reports as E-MCP-007.
  • E-MCP-007 — the same challenge file, checked on disk
  • E-MCP-004server.json registry validation, also checked on disk
