## Fix these first

1. **Wikipedia / Wikidata entity presence** (`wikipedia-presence`, ≈ +6.3): Create a Wikidata item with official website (P856) = your domain; pursue a Wikipedia article once independent coverage exists.
2. **OAuth 2.0 support** (`oauth-support`, ≈ +3.3): Publish /.well-known/oauth-authorization-server with authorization, token and registration endpoints and PKCE S256.
3. **Scoped permissions** (`scoped-permissions`, ≈ +3.3): Declare scopes_supported in the OAuth metadata and per-operation security scopes in the OpenAPI spec.
4. **ARD discovery catalog** (`ard-catalog`, ≈ +3.2): Publish an Agentic Resource Discovery catalog with typed entries and a trust manifest (agenticresourcediscovery.org).
5. **OpenAPI spec published** (`openapi-spec`, ≈ +3.2): Publish OpenAPI 3.x at /openapi.json (alias it if the real file lives elsewhere) and reference it from llms.txt and /.well-known/api-catalog.
6. **NPM/PyPI SDK package** (`npm-sdk-package`, ≈ +3.2): Publish an SDK or CLI under your brand scope and set the package homepage / repository to your domain so it is verifiably yours.
7. **Listed in MCP registries** (`mcp-registry-listed`, ≈ +3.2): Publish server.json to the official MCP registry and an npm package under your scope with the homepage set to your domain.
8. **Agent auth discovery metadata** (`agent-auth-discovery-metadata`, ≈ +2): List the AS origin in PRM authorization_servers and add an agent_auth block (skill / auth_md / register_uri / identity_types_supported) to the AS metadata.
