I'm a newbie to MCP registry publication so please excuse my dumb question

but I get the following

    │ 	* mcp registry: could not get token: failed to get anonymous token (status 404): {"detail":"Endpoint not found. See /docs for the API documentation.","status":404,"title":"Not Found"}
Error: The process '/opt/hostedtoolcache/goreleaser-action/2.13.1/x64/goreleaser' failed with exit code 1

and this is my mcp config:

dockers_v2:
  - images:
      - myuser/{{ .ProjectName }}
    tags:
      - "v{{ .Version }}"
    extra_files:
      - ./
    labels:
      "io.modelcontextprotocol.server.name": "io.github.myuser/myrepo"

mcp:
  name: io.github.myuser/myrepo
  title: my mcp
  description: some description
  homepage: https://github.com/myuser/myrepo
  auth:
    type: none
  repository:
    url: "https://github.com/myuser/myrepo.git"
    source: github
    id: "<id from gh cli>"
  packages:
    - registry_type: oci
      identifier: "ghcr.io/myuser/myrepo:{{ .Version }}"
      transport:
        type: streamable-http
  disable: false

for extra reference, this is the project:

bumping this...

[caarlos0]

  auth:
    type: none

you probably need to setup auth:

  auth:
    type: github-oidc

@caarlos0

thanks Carlos

that was indeed the fix

I now see another issue:

    │ 	* mcp registry: got status code 400: {"title":"Bad Request","status":400,"detail":"Failed to publish server","errors":[{"message":"schema version https://static.modelcontextprotocol.io/schemas/2025-10-17/server.schema.json is not supported. Please use schema version 2025-12-11"}]}

Possibly a bump to the mcp library will fix it?
