LlamaIndex RAG for Balena fleets

Turn your `list_devices` and `list_releases` output into a searchable vector store. Your agent can now answer questions about your entire fleet by querying the index instead of just calling APIs. This creates a grounded knowledge base for your edge infrastructure. You ask about deployment status and get answers backed by the actual current state of your hardware.

Query historical device data in LlamaIndex

Store past configurations and release logs using the MCP tool output. LlamaIndex treats this data as a primary document source for its RAG engine. You stop hallucinating deployment specs. When you ask about a specific device version, the agent retrieves the actual data it indexed previously.

Unified fleet insights with LlamaIndex

Combine your documentation with live Balena API data in one unified index. This allows your agent to correlate device performance with your technical manuals. Developers query the index to find which devices match specific OS versions. It turns your infrastructure management into a standard natural language search task.

Setup guide

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

Common questions about Balena MCP in LlamaIndex

You use the MCP tool spec to pull data and pass it to your indexing pipeline. The integration converts the API responses into searchable chunks automatically.

It provides the context needed to make informed management decisions. You search your fleet's current state to verify which devices require updates before triggering any changes.

Your tags are processed within a secure, ephemeral sandbox. The data only exists in your local vector index and is not shared with the Vinkius platform.

The tool spec supports explicit allow-lists. You control exactly which fleet management tools are available to the agent during index generation.

The server fetches live state directly from the API. When you run your indexing task, the agent retrieves the most recent device telemetry available.
