How to Use the LocalAI MCP in LlamaIndex

Q: How do I register the LocalAI MCP Server tools within LlamaIndex?

Install the required package using pip install llama-index-tools-mcp. Initialize the BasicMCPClient with your Vinkius URL, wrap it in an MCP tool spec, and call totoollistasync() to feed the tools into your FunctionAgent.

Q: Can LlamaIndex query the version of my LocalAI instance?

Your agent can call getversion to check the current running version of your backend. This allows the framework to dynamically toggle features or models based on compatibility.

Q: How does LlamaIndex handle document search using LocalAI embeddings?

The framework calls createembeddings to convert your text documents into vectors. These are stored locally, and the agent uses them to perform semantic searches before calling chatcompletions for the final answer.

Q: Can I filter which LocalAI tools are visible to my LlamaIndex agent?

Yes, you can use the allowedtools filter when setting up your MCP tool selection. This prevents the agent from accidentally calling heavy tools like generateimage when you only want it to do text tasks.

Q: What happens to my biometric data when using LlamaIndex face tools?

Your face images and registered profiles used in faceidentify and faceregister are processed strictly inside your local environment or secure sandbox. No facial features or identity records are ever leaked to external APIs.

Index local LLM outputs and media metadata directly into your LlamaIndex vector stores for secure, private RAG.

Perplexity

Semantic indexing of LocalAI outputs

LlamaIndex takes outputs from tools like `chat_completions` or `open_responses` and indexes them directly into your vector database. This means your agent doesn't just run a tool; it remembers the result for future semantic queries. When you run `create_embeddings` on the returned data, the framework structures the information. You can then query past sessions and get answers grounded in your local hardware's actual historical outputs.

Structured face data retrieval via MCP Server

You can turn visual metadata into searchable knowledge. When the server processes an image using `face_analyze` or `face_verify`, LlamaIndex indexes the resulting demographics and identity markers. Instead of throwing away this metadata, your RAG pipeline stores it as node documents. Future search queries can locate specific files based on verified face matches registered via `face_register`.

Document reranking for precise local retrieval

This framework excels at filtering out noise during document retrieval. By feeding candidate documents through `rerank_documents`, your agent sorts the most relevant context to the top before generating a response. Doing so dramatically reduces the token count sent to `anthropic_messages`. This keeps your local VRAM usage low and prevents the context window from getting cluttered with garbage.

Setup guide

Set up LocalAI 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 LocalAI 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 LocalAI tools.",
)
response = await agent.run("List recent LocalAI data")
