Docker Hub MCP Server

A Model Context Protocol (MCP) server for querying Docker Hub image statistics. Provides pull counts, star counts, descriptions, official/verified status, and publisher catalogs through the public Docker Hub API — no API key required.

Features

• get_image_stats(image) — single image metadata (pulls, stars, last_updated, description, is_official, is_verified)

• search_images(query, limit) — keyword search across Docker Hub

• batch_image_stats(images) — concurrent lookup for up to 100 images

• get_publisher_images(publisher, limit) — catalog all images from a namespace (e.g. library, bitnami, grafana)

uvx docker-hub-mcp

pip

pip install docker-hub-mcp
docker-hub-mcp

Configuration

Claude Desktop

Add to claude_desktop_config.json:

{
  "mcpServers": {
    "docker-hub-mcp": {
      "command": "uvx",
      "args": ["docker-hub-mcp"]
    }
  }
}

Cursor / VS Code

Add to your MCP configuration:

{
  "mcpServers": {
    "docker-hub-mcp": {
      "command": "uvx",
      "args": ["docker-hub-mcp"]
    }
  }
}

Hermes Agent (MCP Gateway)

Add to ~/.hermes/gateway.yaml:

docker-hub-mcp:
  command: uvx docker-hub-mcp
  lazy_spawn: true
  timeout: 30s
  env: {}

Tools

Examples

# Get stats for nginx
get_image_stats({"image": "nginx"})
# → pull_count: 13.2B, star_count: 21K, is_official: true

# Search for postgres
search_images({"query": "postgres", "limit": 5})
# → ranked results with pulls, stars, official flags

# Batch compare web servers
batch_image_stats({"images": ["nginx", "httpd", "caddy", "traefik"]})

# Catalog a publisher
get_publisher_images({"publisher": "bitnami", "limit": 25})
