How to Use the IndoorAtlas (Indoor Positioning) MCP in LangChain

Q: How does the IndoorAtlas (Indoor Positioning) MCP Server handle map generation delays in LangChain?

Because triggermapgeneration is asynchronous, your agent should run a polling loop. You can program the agent to check the status via listfloorplans periodically before moving to the next step in the chain.

Q: Can I trace signal calibration paths using this framework?

Yes, you can pass the output of getfingerprintpaths to a visualization step in your pipeline. The agent pulls the GeoJSON data and parses the routes to verify if technicians covered the entire floor.

Chain IndoorAtlas (Indoor Positioning) tools directly into your LangChain agents to map buildings and trace paths in real time.

Automate Multi-Floor Setups with LangChain Chains

The `create_venue` tool lets your LangChain agent set up a building without manual intervention. It starts by finding the right spot with `list_venues`, creates the space, and uploads the coordinates with `upload_floorplan_geojson` in a single run. By linking these steps, the output of the venue creation feeds directly into the floorplan uploader. You can track this entire data flow in LangSmith to see exactly how your agent maps the coordinates.

Trace and Debug Positioning Runs

The `list_positioning_sessions` tool lets your agent pull historical paths and analyze signal gaps when debugging spotty indoor coverage. It grabs the exact coordinate traces with `get_session_data` to pinpoint where users lose connection. Running this through an MCP Server lets the agent decide when to pull raw coordinates or when to check calibration paths using `get_fingerprint_paths`. You get a clear, step-by-step view of how the agent handles signal data.

Build Self-Correcting Radio Map Pipelines

The `list_floorplans` tool allows your agent to monitor and fix calibration issues on the fly. The agent checks if a floor plan is ready, and if it needs processing, triggers the build with `trigger_map_generation`. If the build fails, the agent looks at the calibration paths to find unmapped zones. It then alerts your field team with specific coordinates that need more Wi-Fi scans.

Setup guide

Set up IndoorAtlas (Indoor Positioning) MCP in LangChain

Prerequisites

Python 3.10+ installed
langchain-mcp-adapters + langgraph packages
Active Vinkius subscription with a valid endpoint token

1

Install dependencies
Run pip install langchain-mcp-adapters langgraph langchain-openai. The MCP adapters package converts MCP tools into native LangChain BaseTool objects.
2

Connect via HTTP transport
Use MultiServerMCPClient with "transport": "http" pointing to your Vinkius endpoint. Replace [YOUR_TOKEN_HERE] with your token from cloud.vinkius.com.
3

Create a ReAct agent
Pass the discovered tools to create_react_agent() from LangGraph. The agent automatically routes IndoorAtlas (Indoor Positioning) tool calls through the MCP protocol.
4

Run with any LLM
Swap ChatOpenAI for ChatAnthropic, ChatGoogleGenerativeAI, or any LangChain-compatible model. The MCP tools work identically across all providers.

agent.py

from langchain_mcp_adapters.client import MultiServerMCPClient
from langgraph.prebuilt import create_react_agent
from langchain_openai import ChatOpenAI

async with MultiServerMCPClient({
    "indooratlas-indoor-positioning-mcp": {
        "transport": "http",
        "url": "https://edge.vinkius.com/[YOUR_TOKEN_HERE]/mcp",
    }
}) as client:
    tools = client.get_tools()

    agent = create_react_agent(
        ChatOpenAI(model="gpt-4o"),
        tools,
    )
    result = await agent.ainvoke({
        "messages": "List recent IndoorAtlas (Indoor Positioning) transactions"
    })
    print(result["messages"][-1].content)

Common questions about IndoorAtlas (Indoor Positioning) MCP in LangChain

You configure the multi-server MCP client to expose the tools directly to your agent. From there, the agent can call `list_venues` to find a building, grab its ID, and immediately pass it to `list_floorplans` to inspect mapped levels.

Yes, by feeding Wi-Fi scan data from your hardware into the `position_from_wifi_scan` tool within a run loop. The agent processes the raw scan, calculates the coordinates, and logs the accuracy metrics directly inside your LangSmith trace.

Because `trigger_map_generation` is asynchronous, your agent should run a polling loop. You can program the agent to check the status via `list_floorplans` periodically before moving to the next step in the chain.

Yes, you can pass the output of `get_fingerprint_paths` to a visualization step in your pipeline. The agent pulls the GeoJSON data and parses the routes to verify if technicians covered the entire floor.

Your raw Wi-Fi scans, floor plans, and coordinate traces are sent directly to the IndoorAtlas secure endpoint. Vinkius runs the MCP server in an isolated sandbox, meaning your coordinates and venue IDs are never stored or logged on our platform.
