Connect Docker Hub to Generic MCP Clients

Connect any stdio-compatible MCP client to local KosmoKrator integration tools.

Register kosmo mcp:serve as the command for a local stdio MCP server. The gateway is local, scoped to this integration, and starts with --write=deny so MCP clients can inspect read-capable tools without receiving write access by default.

Docker Hub MCP Config for Generic MCP Clients

Start with read-only write policy and expand only for trusted projects.

{
  "mcpServers": {
    "kosmokrator-docker": {
      "type": "stdio",
      "command": "kosmo",
      "args": [
        "mcp:serve",
        "--integration=docker",
        "--write=deny"
      ]
    }
  }
}

Run the Gateway Manually

kosmokrator mcp:serve --integration=docker --write=deny

Why Use KosmoKrator Here

Scoped tools

Expose only Docker Hub instead of a broad multi-service tool list.

Local credentials

Reuse credentials already configured for the KosmoKrator CLI and Lua runtime.

Write policy

Start read-only, then opt into ask or allow for trusted workspaces.
