Docker Hub MCP
UnknownThe Docker Hub MCP Server is Docker Inc.'s official server for searching Docker Hub images: namespace, tag, layer-size and Docker Hardened Images metadata without touching the API directly. It runs over stdio with optional HTTP; a Personal Access Token is only needed for higher rate limits. Separately, Docker maintains the MCP Toolkit — the docker/mcp-gateway for 200+ catalog MCPs.
Why this server
- Docker Hub image metadata with no manual Registry API calls — tags, layers, sizes
- Check Docker Hardened Images status right from chat — an image's security-patch state
- The Personal Access Token is optional — basic search works with no auth at all
- The separate MCP Toolkit (docker/mcp-gateway) launches 200+ MCPs from the Docker MCP Catalog on command
Usage examples
Prompt: What tags does the postgres image have on Docker Hub, and which one is Hardened?
Result: The agent fetched the postgres image's metadata and returned the tag list, flagging which ones are Docker Hardened Images.
Prompt: Launch me a Grafana MCP server from the Docker catalog
Result: Via the MCP Toolkit (docker/mcp-gateway), the agent found the Grafana server in the Docker MCP Catalog and started it in a container with one command.
