How to Use the Face++ / Megvii MCP in LlamaIndex

Q: Does Face++ / Megvii work with LlamaIndex filters?

You can use allowedtools filters to restrict which vision functions your agent can access. This keeps your index clean and focused.

Index biometric results into your LlamaIndex knowledge base. Ground your RAG applications in live visual data.

Index visual data for LlamaIndex

Convert `detect_face` and `gesture_detect` outputs into searchable knowledge nodes. You turn raw vision data into structured information that your RAG system can query later. This allows your index to retrieve past observations about faces or gestures. Your system stops hallucinating and starts referencing actual API outcomes.

Query biometric history via LlamaIndex

Store `search_face` results in your vector store to track identities over time. You enable your AI to look back at previous verification attempts and identify patterns in your data. This approach turns a simple API call into a durable record of activity. Your index maintains the context of every interaction for future retrieval.

Connect this MCP Server to your index

Use the tool specification to map every `skeleton_detect` and `detect_body` function to your agent. Your setup integrates visual analysis directly into the ingestion pipeline. You gain the ability to ask questions about the physical presence and posture of subjects captured in your images. The MCP server acts as the primary data source for your knowledge-augmented agent.

Setup guide

Set up Face++ / Megvii 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 Face++ / Megvii 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 Face++ / Megvii tools.",
)
response = await agent.run("List recent Face++ / Megvii data")

Common questions about Face++ / Megvii MCP in LlamaIndex

You wrap the tools in a spec and pass them to your agent. The results become searchable nodes that you can index alongside your text documents.

Yes. Once you receive the tool output, you can persist it in your vector store to build a long-term history of your vision processing.

You can use allowed_tools filters to restrict which vision functions your agent can access. This keeps your index clean and focused.

The data is stored in your local vector database after retrieval. You control the privacy settings and access levels for your stored results.

Images are processed by the API to generate the biometric features. Only the resulting JSON data is indexed, ensuring you keep minimal footprint in your search store.
