7c446e75adAdds support for the Quay.io container registry to the OCI validator. This allows MCP servers hosted on Quay.io to be registered and validated by the official registry. ## Motivation and Context <!-- Why is this change needed? What problem does it solve? --> Quay.io is a major, trusted public OCI registry widely used by the cloud-native and open-source communities. Currently, attempting to publish a server using a Quay image results in an unsupported OCI registry error. This change enables developers to use Quay.io as a first-class hosting option for their MCP server images. ## How Has This Been Tested? <!-- Have you tested this in a real application? Which scenarios were tested? --> - **Unit Tests:** Updated `internal/validators/registries/oci_test.go` to transition Quay.io from a rejected test case to an allowed one. - **Pattern Matching:** Verified that the allowlist correctly handles both specific image identifiers and general pattern matching for the `quay.io` host. - **Local Validation:** Ran `make check` to ensure no regressions in the existing OCI validation logic. ## Breaking Changes <!-- Will users need to update their code or configurations? --> No. This is an additive change that expands the allowlist of supported registries. Existing configurations are unaffected. ## Types of changes <!-- What types of changes does your code introduce? Put an `x` in all the boxes that apply: --> - [ ] Bug fix (non-breaking change which fixes an issue) - [x] New feature (non-breaking change which adds functionality) - [ ] Breaking change (fix or feature that would cause existing functionality to change) - [x] Documentation update ## Checklist <!-- Go over all the following points, and put an `x` in all the boxes that apply. --> - [x] I have read the [MCP Documentation](https://modelcontextprotocol.io) - [x] My code follows the repository's style guidelines - [x] New and existing tests pass locally - [x] I have added appropriate error handling - [x] I have added or updated documentation as needed ## Additional context <!-- Add any other context, implementation notes, or design decisions --> The implementation follows the existing pattern for OCI registries: 1. Added a `RegistryURLQuay` constant to `pkg/model` for consistency. 2. Hardcoded `quay.io` into the `allowedOCIRegistries` map in the validator to minimize architectural complexity. 3. Updated all relevant documentation files (`package-types.mdx`, `generic-server-json.md`, and `official-registry-requirements.md`) to ensure the source of truth is updated across the project. 4. Validation remains scoped to public images; no private registry authentication was added for this host.
