Docker Hub MCP: Documentation
Updated:
Connection
Docker Hub MCP: docker/hub-mcp — runs over stdio (an HTTP mode is also available). Authorization isn't required for public search; a Personal Access Token from Docker Hub → Account Settings → Security raises rate limits and unlocks access to private repositories. Setup details are in github.com/docker/hub-mcp.
Separately — the MCP Toolkit: the docker/mcp-gateway, which launches MCP servers from the Docker MCP Catalog (200+ of them) as containers, isolated from the host system. Installs as a Docker Desktop extension or a standalone CLI tool.
Tools
- Docker Hub MCP: image search, namespace and organization browsing, tag lists with metadata (size, architecture, publish date), Docker Hardened Images status.
- MCP Toolkit: catalog server search, starting/stopping a containerized MCP server, managing which tools are exposed to the agent through a single gateway.
Agent flow
"What tags does the postgres image have, and which one is Hardened?", "find the official nginx image and show its size", "launch me a Grafana MCP server from the Docker catalog", "what MCPs does the catalog have for working with databases?".
Pricing
Both servers are free and open; higher Docker Hub API rate limits require free signup and a Personal Access Token.
