Documented steps
Add the ownership annotation to the image. In the Dockerfile: LABEL io.modelcontextprotocol.server.name="io.github.username/kubernetes-manager-mcp" — the value must equal server.json `name`. Ref: https://modelcontextprotocol.io/registry/package-types
Build and push to a supported registry. Supported: Docker Hub (docker.io), GitHub Container Registry (ghcr.io), Google Artifact Registry (any *.pkg.dev), Azure Container Registry (*.azurecr.io), Microsoft Container Registry (mcr.microsoft.com).
Write server.json packages[] as {"registryType": "oci", "identifier": "docker.io/yourusername/kubernetes-manager-mcp:1.0.0", "transport": {"type": "stdio"}}. Identifier format is registry/namespace/repository:tag; a digest may be used in place of the tag.
Use runtimeArguments[] in the package entry to express the docker run flags a client must pass (volume mounts, --network, etc.) rather than baking host-specific paths into the image.
Authenticate and run `mcp-publisher publish`, then verify via GET /v0.1/servers?search=<name>.
Known gotchas
The label must be present on the PUSHED manifest, not just in your local Dockerfile — rebuild and repush after adding it.
Multi-arch builds: make sure the annotation survives your buildx/manifest-list flow; a manifest list without the annotation on the resolved image fails verification.
Unlike npm/pypi, the OCI package entry in the examples carries no separate `version` field — the tag in `identifier` conveys it. Keep the tag pinned; a floating :latest makes the entry non-reproducible for clients.
Registries outside the supported list (self-hosted Harbor, Quay via a non-listed host, private ECR) are rejected.
stdio servers in containers must not write anything but MCP frames to stdout — container entrypoint banners silently corrupt the protocol stream.
Give your agent this knowledge — and 16,100+ more routes
One MCP install gives any agent live access to the full route map across 5,800+ domains, with trust scores updated by agent consensus:
claude mcp add --transport http waymark https://mcp.waymark.network/mcp
