What is the Hologram.io MCP Server?
Connect your Hologram.io IoT platform to any AI agent and take full control of your global cellular connectivity and device fleet through natural conversation.
What you can do
- Device Oversight — List all IoT devices in your account, retrieve detailed metadata, and monitor their active status.
- SIM Card Management — Access lists of SIM cards (cellular links) and their associated data plans to ensure seamless connectivity.
- Data Usage Monitoring — Retrieve recent data sessions, daily usage statistics, and current billing cycle summaries.
- Connectivity Control — Quickly pause or unpause data services for specific SIM cards directly from the chat interface.
- Location Insights — Access approximate GPS coordinates for your entire fleet based on cell tower triangulation.
- SMS Tracking — Retrieve the history of device-originated SMS messages for troubleshooting and logging.
How it works
1. Subscribe to this server
2. Enter your Hologram API Key (found in Dashboard > API)
3. Start managing your IoT fleet from Claude, Cursor, or any MCP-compatible client
No more manual exporting of usage logs or jumping between complex fleet management screens. Your AI assistant acts as a dedicated IoT Operations Manager or Network Specialist.
Who is this for?
- IoT Engineers — instantly check device connectivity and retrieve data session logs during development.
- Fleet Managers — automate the process of monitoring data overages and pausing inactive SIMs.
- Operations Leads — maintain a real-time overview of fleet location and billing usage.

How Vinkius secures
Hologram.io for LangChain
Every tool call from LangChain to the Hologram.io MCP Server is protected by DLP redaction, cryptographic audit chains, V8 sandbox isolation, kill switch, and financial circuit breakers.
Frequently asked questions
How do I find my Hologram.io API Key?
Log in to your Hologram dashboard, click on your profile/organization name, navigate to Settings, and select the API tab. You will find your unique API Key there.
Can I pause data for a specific device?
Yes! Use the pause_sim_data tool by providing the unique cellular link ID for that device. This will change its state to 'suspended' and stop data usage immediately.
How accurate is the device location feature?
The location data provided by get_device_locations is approximate and based on cell tower triangulation. It is generally accurate within a few hundred meters to a few miles depending on tower density.
Is the integration secure for managing my IoT fleet?
Absolutely. The integration uses industry-standard Basic Authentication over HTTPS. Your credentials and connectivity data are encrypted and stored securely within the Vinkius Cloud infrastructure.
How does LangChain connect to MCP servers?
Use langchain-mcp-adapters to create an MCP client. LangChain discovers all tools and wraps them as native LangChain tools compatible with any agent type.
Which LangChain agent types work with MCP?
All agent types including ReAct, OpenAI Functions, and custom agents work with MCP tools. The tools appear as standard LangChain tools after the adapter wraps them.
Can I trace MCP tool calls in LangSmith?
Yes. All MCP tool invocations appear as traced steps in LangSmith, showing input parameters, response payloads, latency, and token usage.
