How to Use the Hologram.io MCP in LlamaIndex

Q: Is Hologram.io data searchable in LlamaIndex?

Yes. Once you index the output of tools like listiotdevices, your agent can perform semantic searches across your entire device inventory.

Index your live IoT data into LlamaIndex for grounded, accurate analysis with Hologram.io.

Perplexity

Ground your RAG pipeline in live fleet data

Feed the output of `list_iot_devices` into your LlamaIndex knowledge base for semantic search. Instead of guessing device states, your agent queries an index built directly from your live Hologram.io account. This ensures your agent answers questions based on actual cellular connectivity status. It removes hallucinations by grounding every response in current API data.

Query historical usage patterns with index support

Use `get_recent_data_sessions` to populate your vector store with historical connectivity logs. Your LlamaIndex application then searches these sessions to identify long-term trends across your deployed hardware. This approach lets you ask natural language questions about your fleet's behavior over time. The agent retrieves the relevant session data and synthesizes a clear answer for your team.

Map device locations with semantic context

Retrieve approximate coordinates via `get_device_locations` and index them alongside your device metadata. LlamaIndex then associates specific hardware IDs with their geographic footprint for spatial reasoning. Your agent uses this combined index to explain where devices are operating relative to your fleet requirements. It makes your cellular infrastructure queryable in plain English.

Setup guide

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

Common questions about Hologram.io MCP in LlamaIndex

You use the MCP tool spec to fetch the tool list, then pass those results into your LlamaIndex ingest pipeline. This creates a searchable knowledge base from your live cellular data.

Yes. Once you index the output of tools like `list_iot_devices`, your agent can perform semantic searches across your entire device inventory.

The tools integrate directly into the FunctionAgent class. You define the allowed tools, and the agent uses them to gather the info needed for its knowledge base.

You can trigger tool calls to refresh your index whenever the agent detects a need for current status. This keeps your knowledge base synced with the latest cellular activity.

Your device usage logs and SIM identifiers remain within the scope of your secure index. Access is restricted to the tools you initialize, ensuring no unauthorized exposure of your fleet metrics.
