At a glance: Official vendor investment is strong but narrowly scoped. Docker Hub has an official 13-tool MCP server. JFrog has the most comprehensive offering at 22+ tools. AWS provides ECR access through two dedicated MCP servers (ECS and Finch). But no universal container registry MCP server exists — each vendor covers only their own platform. 12+ servers across 8 platforms. Rating: 3.5/5.
Docker Hub (Official)
| Server | Stars | Language | Tools | Auth | Transport |
|---|---|---|---|---|---|
| docker/hub-mcp | ~130 | TypeScript | 13 | Optional PAT | stdio |
Docker Hub's official MCP server brings AI-powered image discovery across 100,000+ public images. 130 stars, Apache 2.0, backed by Docker, Inc.
13 tools across three domains:
Image Discovery (2 tools):
| Tool | What it does |
|---|---|
search |
AI-powered search across Docker Hub with architecture and OS filtering |
docker_hardened_images |
Discover Docker's security-hardened official images |
Repository Management (5 tools):
| Tool | What it does |
|---|---|
get_namespaces |
List available Docker Hub namespaces |
list_repositories_by_namespace |
Browse repositories within a namespace |
get_repository_info |
Full repository metadata — description, stars, pulls |
check_repository |
Verify a repository exists |
create_repository |
Create a new repository (requires PAT) |
Tag Management (4 tools):
| Tool | What it does |
|---|---|
list_repository_tags |
Browse available tags with filtering |
read_repository_tag |
Inspect a specific tag — layers, size, architecture |
check_repository_tag |
Verify a tag exists |
update_repository_info |
Update repository description and settings |
The AI-powered search is the standout feature — it understands natural language queries like "lightweight Python image for machine learning" and filters by architecture (ARM64, AMD64) and OS. The Docker MCP Toolkit integration means one-click setup in Claude Desktop, Cursor, and VS Code.
JFrog Artifactory (Official)
| Server | Stars | Language | Tools | Auth | Transport |
|---|---|---|---|---|---|
| jfrog/mcp-jfrog | ~112 | TypeScript | 22+ | JFrog token | stdio, SSE |
JFrog's official MCP server is the most comprehensive artifact management integration available. Supports Docker, Maven, npm, PyPI, and dozens of other package formats.
22+ tools across six categories:
- Repository Management (7 tools) — including AQL (Artifactory Query Language) for structured queries across all repositories
- Build Management (2 tools) — track which builds produced which container images
- Runtime Monitoring (3 tools) — see which container images are actively running across your infrastructure. Unique capability — no other MCP server connects registry data to runtime state
- Access Control (4 tools) — project and environment management
- Catalog & Curation (5 tools) — package info, version vulnerabilities, curation status via JFrog Xray
- Security Scanning (1 tool) — combined vulnerability and compliance summary
AWS ECR (via ECS + Finch MCP Servers)
AWS doesn't have a dedicated ECR MCP server. Instead, ECR functionality is distributed across two servers in the awslabs/mcp monorepo (~4,700 stars):
ECS MCP Server — includes ECR repository creation and image push as part of ECS deployment workflows. Tools: containerize_app (generate Dockerfiles), build_and_push_image_to_ecr (automated ECR repo creation + Docker build + push), ecs_resource_management. Tightly coupled to ECS deployment.
Finch MCP Server — 3 focused tools: finch_build_container_image (multi-platform builds), finch_push_image (push to ECR with hash-based tagging), finch_create_ecr_repo (create ECR repos with immutable tags). The immutable tags enforcement prevents supply chain attacks from tag overwriting.
Azure ACR (via Microsoft MCP)
| Server | Stars | Language | Tools | Auth | Transport |
|---|---|---|---|---|---|
| microsoft/mcp | ~2,800 | C# | 2 ACR tools | Azure credentials | stdio |
Two read-only tools inside Microsoft's broader Azure MCP server: azmcp-acr-registry-list and azmcp-acr-registry-repository-list. Enough for discovery but not for registry management. Minimal compared to other Azure integrations in the same server.
Harbor (Community)
| Server | Stars | Language | Tools | Auth | Transport |
|---|---|---|---|---|---|
| nomagicln/mcp-harbor | ~6 | TypeScript | 11 | Harbor credentials | stdio |
The only MCP server for Harbor, the CNCF-graduated open source container registry. 11 tools across four domains: Project Management (4), Repository Management (2), Tag Management (2), Helm Charts (3). Missing: vulnerability scanning integration, robot account management, replication policies.
Sonatype Nexus (Community)
brianveltman/sonatype-mcp (7 stars, TypeScript, 16 tools) — The most comprehensive Nexus MCP server spanning repository, component, asset, system, and firewall management. Covers Docker-hosted repositories alongside Maven, npm, PyPI.
addozhang/nexus-mcp-server (1 star, Python, 6 tools) — Lighter alternative with explicit Docker support: list_docker_images and get_docker_tags for browsing container images stored in Nexus.
GCP Artifact Registry (Community)
| Server | Stars | Language | Tools | Auth | Transport |
|---|---|---|---|---|---|
| enesbol/gcp-mcp | ~6 | Python | Multiple | GCP credentials | stdio |
The only MCP server covering Google Cloud Artifact Registry, buried inside a broader GCP services MCP server. Google has no official Artifact Registry MCP server — a notable gap.
Container Image Scanning (via Trivy)
| Server | Stars | Language | Tools | Auth | Transport |
|---|---|---|---|---|---|
| aquasecurity/trivy-mcp | ~37 | Go | Multiple | Optional | stdio, HTTP, SSE |
Trivy's MCP plugin scans container images for vulnerabilities through natural language queries. Official Aqua Security project. Ask "Are there any critical CVEs in nginx:1.25?" and Trivy scans the image layers. Complements registry management servers.
What's Missing
- No universal registry client — every server is vendor-specific. A server that speaks the OCI Distribution API could manage any compliant registry through one interface.
- Image lifecycle management — no server helps with tag retention policies, garbage collection, or automated cleanup.
- Multi-registry synchronization — no server helps mirror or replicate images across registries.
- SBOM and provenance — no registry MCP server exposes SBOM data or image provenance (Sigstore/cosign signatures).
- GHCR is completely uncovered — surprising given GitHub's dominance and investment in MCP.
Bottom Line
Rating: 3.5/5 — Solid vendor coverage from Docker Hub and JFrog with comprehensive official servers. AWS provides good ECR integration through ECS and Finch servers. But the ecosystem is fragmented (no cross-registry server), Azure and GCP coverage is minimal, GHCR is uncovered, and community projects for Harbor and Nexus have very low adoption.
Best for image discovery: Docker Hub MCP (docker/hub-mcp). Best for artifact lifecycle: JFrog MCP (jfrog/mcp-jfrog). Best for AWS workflows: ECS + Finch MCP servers. Best for self-hosted registries: Harbor MCP or Sonatype MCP for Nexus.
