Query your registry with LlamaIndex

Turn your registry metadata into searchable knowledge. Use `list_repositories` to pull your current state, then index that data so you can ask your agent about image versions or usage patterns. This gives your agent a complete view of your ecosystem. It answers questions about repository history using actual data retrieved from the API.

Retrieve tag details for RAG tasks

Fetch precise information on image versions using `get_tag`. Your agent uses this data to ground its responses in reality instead of relying on outdated internal knowledge. It pulls the digest and size for every tag you need. You get a clear audit trail for every image version currently hosted in your registry.

Manage organization structures in LlamaIndex

Explore your teams and namespaces using `list_organizations`. This tool maps out your entire Docker Hub account structure so your agent understands where it has permission to operate. It clarifies the hierarchy of your resources. Your agent uses this map to navigate between different namespaces without needing hardcoded paths.

Setup guide

Set up Docker Hub MCP in LlamaIndex

Prerequisites

Python 3.10+ installed
llama-index-tools-mcp package
Active Vinkius subscription with a valid endpoint token

1

Install dependencies
Run pip install llama-index-tools-mcp llama-index-llms-openai. The MCP tools package provides BasicMCPClient and McpToolSpec.
2

Connect with BasicMCPClient
Point BasicMCPClient to your Vinkius endpoint URL. Replace [YOUR_TOKEN_HERE] with your token from cloud.vinkius.com. Supports SSE and Streamable HTTP transports.
3

Convert to LlamaIndex tools
Call mcp_tool_spec.to_tool_list_async() to convert all Docker Hub MCP tools into native FunctionTool objects that any LlamaIndex agent can use.
4

Run with any LLM
Create a FunctionAgent with the tools and your preferred LLM. Swap OpenAI for Anthropic, Gemini, or any LlamaIndex-supported provider.

agent.py

from llama_index.tools.mcp import BasicMCPClient, McpToolSpec
from llama_index.core.agent.workflow import FunctionAgent
from llama_index.llms.openai import OpenAI

# Connect to the MCP
mcp_client = BasicMCPClient(
    "https://edge.vinkius.com/[YOUR_TOKEN_HERE]/mcp"
)
mcp_tool_spec = McpToolSpec(client=mcp_client)

# Convert MCP tools to LlamaIndex tools
tools = await mcp_tool_spec.to_tool_list_async()

# Create and run the agent
agent = FunctionAgent(
    tools=tools,
    llm=OpenAI(model="gpt-4o"),
    system_prompt="You have access to Docker Hub tools.",
)
response = await agent.run("List recent Docker Hub data")
