ADS-B MCP Server

A Model Context Protocol (MCP) server that exposes the data of a typical ADS-B feeder instance for use from within Claude (and possibly other LLMs).

This was initially written in order to provide an MCP server connected to the ADS-B Feeder Image running an Ultrafeeder container - but it will work with any feeder that is providing the APIs typically associated with readsb / tar1090.

Features

This MCP server so far provides access to:

• Aircraft Data: Real-time aircraft positions, callsigns, altitudes, and tracking information plus optionally (where available) route information for commercial flights

• Receiver Statistics: Performance metrics, message counts, and system status

• Search Functionality: Find specific aircraft by callsign, hex code, or flight number

• Range Statistics: Coverage area and signal range information

Installation

Prerequisites

• Node.js 18.0 or higher

• npm (comes with Node.js)

• Access to an ADS-B feeder

Install Dependencies

# Clone the repository
git clone https://github.com/dirkhh/adsb-mcp-server.git
cd adsb-mcp-server

# Install dependencies
npm install

# Build the project
npm run build

MCP Client Setup Guide

This guide will help you connect various MCP clients to your ADS-B MCP server.

Prerequisites

1. Running ADS-B Feeder: Make sure your ADS-B feeder is running and accessible - the easiest way to do that may be running the ADS-B Feeder Image

2. Python MCP Server: The readsb MCP server should be working

3. Network Access: Client needs access to your feeder's API endpoints

Option 1: Claude Desktop (Recommended)

Step 1: Configure Claude Desktop

Recommended: Use the automatic setup script:

npm run build
node dist/setup_remote_config.js

This script will:

• Prompt you for your ADS-B feeder host and port

• Automatically create the correct configuration

• Merge with existing Claude Desktop configuration if present

• Provide clear instructions for next steps

Step 2: Restart Claude Desktop (or Reload MCP Configuration if your version of Claude Desktop supports that)

Close and reopen Claude Desktop to load the new configuration. As of this writing, not all versions of Claude have an option to reload its configuration.

Step 3: Test the Connection

In Claude Desktop, try asking:

• "What are the 5 closest planes to my feeder?"

• "Show me aircraft to the east of my location"

Option 2: MCP Inspector

Install MCP Inspector

npm install -g @modelcontextprotocol/inspector

Run with ADS-B MCP server

npm run build
npx @modelcontextprotocol/inspector node dist/src/readsb_mcp_server.js --base-url http://adsb-feeder.local

This will open a web interface where you can test the MCP server tools.

Creating MCP Bundles

You can create an MCP Bundle (.mcpb file) for easy distribution using the official MCPB tool:

# Install the official MCPB tool (Node.js required)
npm install -g @anthropic-ai/mcpb

# Build the project
npm run build

# Create bundle using official tool
mcpb pack .

The bundle will be created as adsb-mcp-server.mcpb and can be distributed and installed in MCP-compatible clients. The bundle includes all Node.js dependencies for self-contained operation.

Option 3: Custom Node.js Client

Use the included simple MCP client:

npm run build
node dist/test/remote_mcp_client.js

This provides an interactive command-line interface to test all the MCP tools.

Option 4: Test Script

Run the basic connection test:

npm run build
node dist/test/test_remote_connection.js

This will verify that the ADS-B MCP server is working correctly.

Configuration Options

Base URL Configuration

Adjust the --base-url parameter based on your setup:

• Typical ADS-B Feeder Image: (by default adsb-feeder.local is used as host)

• Feeder with known IP address --base-url http://192.168.123.45

• Local feeder running on this system: --base-url http://localhost

• Running in a container in the ADS-B Feeder Image adsb_im_bridge Docker network: --base-url http://ultrafeeder

Port Configuration

The server connects to these readsb endpoints:

• Port 8080: REST API (/data/aircraft.json, /data/stats.json)

Make sure these ports are accessible from your MCP client. If your tar1090 runs on a different port, adjust the command line accordingly, e.g. --base-url http://100.99.98.97:6543

Troubleshooting

Connection Issues

1. Check if you can manually get to the ADS-B data:

   curl http://adsb-feeder.local:8080/data/aircraft.json

Claude configuration issues

1. Check the Claude MCP logs:

e.g., ~/Library/Logs/Claude/mcp-server-readsb.log on macOS

Performance Issues

1. Limit result counts to avoid overwhelming responses

2. Use distance filters to reduce data processing

3. Monitor memory usage for large aircraft datasets

Example Queries

Once connected, you can ask natural language questions like:

• "What are the 5 closest aircraft to my feeder?"

• "Show me all planes to the east within 50 miles"

• "Are there any aircraft to the north?"

• "What's the closest plane to the south?"

• "Find aircraft in the northeast quadrant"

• "Search for flight UAL123"

• "Show me receiver statistics"

Advanced Configuration

Custom Auto-Approval

Configure which tools require approval:

{
  "autoApprove": [
    "get_aircraft_data",
    "get_receiver_stats"
  ]
}

Tools not in autoApprove will require manual approval in Claude Desktop.
