Overview

Dockerhub Api is a production-grade Agent and Model Context Protocol (MCP) server that wraps the official Docker Hub API v2 (https://hub.docker.com): repositories and tags, immutable tags, personal and organization access tokens, organization members/settings/invites, teams, audit logs, and SCIM 2.0 provisioning — plus the Registry HTTP API v2 (registry-1.docker.io: manifests, blobs, digests, multi-arch inspection, OCI referrers, and gated push/remove) and Docker Scout (api.scout.docker.com: CVE/SBOM/policy intelligence).

---

Key Features

• Consolidated Action-Routed MCP Tools: Nine togglable tool modules (hub_auth, hub_repos, hub_org, hub_teams, hub_audit, hub_scim, hub_admin, hub_registry, hub_scout) minimize token overhead in LLM contexts.
• Three API surfaces, one package: the Hub management API, the Registry v2 image API (its own host + per-repository scoped-token auth), and Docker Scout — each with the same uniform envelope, redaction, and gating.
• JWT Auth Lifecycle: Short-lived bearer minted from POST /v2/auth/token (password, PAT dckr_pat_*, or org access token), cached and refreshed before expiry, with one transparent re-mint on 401.
• Rate-Limit Telemetry: X-RateLimit-* headers surfaced in every result; HTTP 429 retried with bounded Retry-After backoff.
• Safety by Default: Removes and org-settings writes are gated behind DOCKERHUB_ALLOW_DESTRUCTIVE (default False); secrets are redacted from tool results (plaintext tokens appear exactly once — on creation). Repository creation stays enabled: it is the primary release-provisioning use case.
• Integrated Graph Agent: Built-in Pydantic AI agent (dockerhub-agent) with A2A and AG-UI web interfaces.
• Native Telemetry & Tracing: Out-of-the-box OpenTelemetry exports and Langfuse tracing via agent-connector-sdk.

Installation

pip install dockerhub-api            # API client only
pip install "dockerhub-api[mcp]"     # + MCP server
pip install "dockerhub-api[all]"     # everything

Extra	Adds
mcp	FastMCP server (dockerhub-mcp) via agent-connector-sdk
agent	Pydantic-AI A2A agent (dockerhub-agent) + Logfire via agent-connector-sdk
all	mcp + agent
test	pytest toolchain for development

# Connector-focused MCP server (includes the shared graph engine)
uv pip install "dockerhub-api[mcp]"

# Agent runtime (adds model orchestration to the shared graph engine)

# Everything (development)
uv pip install "dockerhub-api[all]"      # or: python -m pip install "dockerhub-api[all]"

Container images (:mcp)

One multi-stage docker/Dockerfile builds the MCP-only image (--target mcp):

Image tag	Build target	Contents	Entrypoint
example/dockerhub-api:mcp	--target mcp	dockerhub-api[mcp] — connector-focused, includes epistemic-graph[full]; no model-orchestration stack	dockerhub-mcp

docker build --target mcp   -t example/dockerhub-api:mcp    docker/   # connector-focused MCP server

agent (immutable agent digest) with a co-located :mcp sidecar.

Knowledge-graph database (epistemic-graph)

Agent Connector SDK core dependency (epistemic-graph[full]). The [mcp] extra keeps deployments can use the bundled engine. For production or shared state, run epistemic-graph as a dedicated database service and configure the runtime to use it. Deployment recipes (single-node + Raft HA), connection configuration, and architecture diagrams are documented in the epistemic-graph deployment guide.

---

Usage

Python API / CLI

from dockerhub_api.auth import get_client

api = get_client()  # reads DOCKERHUB_URL / DOCKER_HUB_USER / DOCKER_HUB_TOKEN

repos = api.get_repositories(namespace="acme", ordering="-last_updated")
api.create_repository(namespace="acme", name="release-images", is_private=True)
tags = api.get_repository_tags(namespace="acme", repository="release-images")
print(api.rate_limit)  # latest X-RateLimit-* snapshot

Every client method returns a uniform envelope: {"status_code": int, "data": ..., "rate_limit": {"limit", "remaining", "reset"}}.

MCP Configuration Examples

Install the connector-focused [mcp] extra. Examples use dockerhub-api[mcp] to add FastMCP / FastAPI through agent-connector-sdk; the required Agent Connector SDK core still carries epistemic-graph[full]. The [agent-runtime] extra additionally enables model orchestration.

Runtime references require an alias-aware launcher such as Arbora. Other launchers must omit those entries and inject the resolved values through their own runtime secret boundary.

For containerized network HTTP, supply an authenticated TLS ingress (or direct server TLS), exact MCP_ALLOWED_HOSTS, and an exact trusted-proxy CIDR policy through the operator-owned deployment profile. The generator does not emit an unauthenticated non-loopback listener.

Additional Deployment Options

dockerhub-api can run as a local stdio process or container, or behind a remote network boundary. The Deployment guide carries the detailed transport contract.

• Local container — launch a reviewed immutable image as a least-privilege stdio child with no listener or published port.
• Remote URL — connect through an operator-supplied authenticated HTTPS ingress. Keep its URL, outbound identity references, trust profile, and exact MCP_ALLOWED_HOSTS in AgentConfig.

Safety Model

Operation class	Default	Override
Reads (repos, tags, members, logs, SCIM)	allowed	—
Repository create / immutable-tag config / invites / role updates	allowed	—
Removes (PATs, OATs, groups, members, invites)	blocked	DOCKERHUB_ALLOW_DESTRUCTIVE=True
Org-settings writes (PUT /v2/orgs/{org}/settings)	blocked	DOCKERHUB_ALLOW_DESTRUCTIVE=True

Governed capability contract

This package ships a compact canonical skill surface with specialist procedures kept as referenced workflows. The current MCP tools, skill metadata, connector_manifest.yml, ontology, mappings, shapes, fixtures, migrations, tool-schema fingerprints, and certification metadata form one versioned capability contract. Validate them together; do not rely on stale tool names or historical per-task skill wrappers.

Runtime endpoints, credentials, certificate trust, tenant identity, retention, and observability policy are deployment inputs and are never packaged values. See Configuration, trust, and privacy before enabling a network transport, connector ingestion, Arbora delegation, or trace export.
