Deployment¶

Deployment Options¶

dockerhub-api supports local stdio, a loopback-only development listener, a least-privilege stdio container, and a remote authenticated HTTPS boundary. Provider endpoint, credential, selector, identity, and trust material are supplied at runtime through AgentConfig; none is stored in this repository.

Installed stdio process¶

{
  "mcpServers": {
    "dockerhub": {
      "command": "dockerhub-mcp",
      "args": [],
      "env": {"MCP_TOOL_MODE": "intent"}
    }
  }
}

Loopback development listener¶

dockerhub-mcp --transport streamable-http --host 127.0.0.1 --port 8000

Do not expose this listener beyond loopback. Network deployments require direct TLS or an explicitly trusted TLS-terminating ingress, configured authentication, exact MCP_ALLOWED_HOSTS, and an exact trusted-proxy CIDR policy.

Least-privilege local container¶

docker run -i --rm \
  --read-only \
  --cap-drop=ALL \
  --security-opt=no-new-privileges \
  --pids-limit=256 \
  --tmpfs /tmp:rw,noexec,nosuid,nodev,size=64m \
  -e TRANSPORT=stdio \
  registry.example.invalid/dockerhub-api@sha256:<digest> dockerhub-mcp

The operator projects the selected AgentConfig profile into the process at runtime; the image remains immutable and contains no environment connection profile.

Remote authenticated HTTPS endpoint¶

{
  "mcpServers": {
    "dockerhub": {"url": "https://service.example.invalid/mcp"}
  }
}

Store the real remote URL, outbound identity reference, and TLS-profile reference in AgentConfig, not in MCP client JSON or documentation.

MCP server (standalone)¶

pip install "dockerhub-api[mcp]"
export DOCKERHUB_USERNAME=youruser
export DOCKERHUB_TOKEN=dckr_pat_xxx
dockerhub-mcp --transport streamable-http --host 0.0.0.0 --port 8000

Transports: stdio (default), streamable-http, sse.

Docker Compose — MCP only¶

cp .env.example .env       # fill in DOCKERHUB_* values
docker compose -f docker/mcp.compose.yml up -d

Docker Compose — MCP + A2A agent¶

docker compose -f docker/agent.compose.yml up -d

This starts:

dockerhub-api-mcp on port 8000 (streamable-http, /health endpoint)
dockerhub-api-agent on port 9018 (A2A + AG-UI web interface), pointed at the MCP service via MCP_URL

MCP client registration¶

Register the server in any MCP-capable client using the template in mcp_config.json:

{
  "mcpServers": {
    "dockerhub-api": {
      "command": "uv",
      "args": ["run", "dockerhub-mcp"],
      "env": {
        "DOCKERHUB_USERNAME": "youruser",
        "DOCKERHUB_TOKEN": "dckr_pat_xxx",
        "DOCKERHUB_ALLOW_DESTRUCTIVE": "False"
      }
    }
  }
}

Security posture¶

Leave DOCKERHUB_ALLOW_DESTRUCTIVE=False in shared deployments; enable it only for operator sessions that genuinely need deletes or org-settings writes.
Prefer organization access tokens scoped with TYPE_REPO path globs over account-wide PATs for CI/CD.
Eunomia policies and OTEL/Langfuse tracing are available through the agent-utilities server bootstrap (see .env.example).

Debug image¶

docker/debug.Dockerfile builds the package from the working tree with dev tooling (uv, ripgrep, starship) for interactive debugging:

docker build -f docker/debug.Dockerfile -t dockerhub-api:debug .
docker run --rm -it dockerhub-api:debug bash
