Docker Hub MCP Server
Enables AI assistants to search, analyze, and manage Docker images on Docker Hub through standardized MCP tools, with features including security scanning, layer analysis, and image comparison.
Caution. Specific findings reduced this grade. They are listed on the page. Grades reflect the full trust pyramid: code, verification depth, and reputation. New projects cap at C until adoption is earned.

The grade above is for the source repository. Registries can serve a different version, so we mark the ones we were not able to read.
These names and descriptions are the publisher's own, read from the source code. We print them as written. Our assessment is the findings above, not this list.
docker_analyze_layersAnalyze image layers to understand composition, identify optimization opportunities, and provide insights about the build process.
docker_batch_image_detailsEfficiently fetch detailed information for multiple Docker repositories in a single operation. Supports parallel processing and configurable data inclusion.
docker_compare_imagesCompare two Docker images to analyze differences in layers, sizes, base images, and provide optimization recommendations.
docker_enhanced_vulnerability_analysisComprehensive vulnerability analysis with CVE cross-referencing, severity filtering, security policy validation, and multiple export formats.
docker_estimate_pull_sizeCalculate the estimated download size for pulling a Docker image, considering layer deduplication, compression, and existing cached layers. Useful for planning deployments and bandwidth requirements.
docker_export_dataExport Docker image data in various formats including dependency trees, CSV analysis, and structured data for external consumption.
docker_get_dockerfileAttempt to retrieve the Dockerfile content for a Docker image. Note: This is only available for automated builds and may not be accessible for all repositories.
docker_get_image_detailsGet comprehensive details about a Docker repository including description, statistics, and metadata.
docker_get_image_historyRetrieve detailed build history, layer creation timeline, and Dockerfile command reconstruction for a Docker image to understand its construction process.
docker_get_manifestRetrieve the Docker image manifest containing layer information, configuration details, and metadata for a specific tag.
docker_get_statsGet comprehensive statistics for a Docker repository including pull count, star count, and popularity metrics with historical trends estimation.
docker_get_vulnerabilitiesRetrieve security vulnerability scan results for a Docker image. Note: Vulnerability scanning may not be available for all images and may require authentication.
docker_list_tagsList all available tags for a Docker repository with detailed information about each tag including size, architectures, and timestamps.
docker_search_imagesSearch Docker Hub for images by query. Returns a list of images with metadata including stars, pulls, and descriptions.

No tools have read-only/destructive annotations
Add readOnlyHint or destructiveHint annotations to every tool so hosts can warn users before invoking.
All four hints declared on every tool
14/14 tools missing one or more hints — docker_analyze_layers (missing: readOnlyHint, destructiveHint, idempotentHint, openWorldHint); docker_batch_image_details (missing: readOnlyHint, destructiveHint, idempotentHint, openWorldHint); docker_compare_images (missing: readOnlyHint, destructiveHint, idempotentHint, openWorldHint), +11 more. OpenAI's directory rejects tools where any of the four hints are missing or non-boolean.
For every tool, set all four hints (readOnlyHint, destructiveHint, idempotentHint, openWorldHint) to explicit true/false values that match the handler’s actual behaviour.
Tool test coverage
11/14 tools referenced in tests (79%)
Write tests that reference each tool by name so every tool has at least one test.
Production dependencies are patched
0 critical, 14 high severity in production deps — @modelcontextprotocol/sdk@1.0.0 (high), axios@1.6.2 (high)
Run npm audit fix, or upgrade the affected packages to a non-vulnerable version.
Dev dependencies
2 critical/high in dev-only deps (does not ship to users)
Upgrade dev dependencies when convenient.
