Container Registry MCP Servers — Docker Hub, ECR, ACR, JFrog, Harbor, and Beyond

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)

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):

Repository Management (5 tools):

Tag Management (4 tools):

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)

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)

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)

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)

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)

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

1. 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.
2. Image lifecycle management — no server helps with tag retention policies, garbage collection, or automated cleanup.
3. Multi-registry synchronization — no server helps mirror or replicate images across registries.
4. SBOM and provenance — no registry MCP server exposes SBOM data or image provenance (Sigstore/cosign signatures).
5. 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.
