Installation
Configuration
Your SimBrief **Pilot ID** is passed via an environment variable in the MCP config — no code changes needed.
Find your Pilot ID under SimBrief → Account Settings → **Pilot ID**.
Claude Desktop integration
Add the following to your claude_desktop_config.json:
**macOS:** ~/Library/Application Support/Claude/claude_desktop_config.json
**Windows:** %APPDATA%\Claude\claude_desktop_config.json
Then restart Claude Desktop. The SimBrief tools will appear automatically.
> The server will refuse to start with a clear error message if SIMBRIEF_PILOT_ID is not set.
Usage examples
Once connected, you can ask Claude things like:
- *"What's my latest flight plan?"*
- *"Show me the weather for my next flight."*
- *"How much fuel do I have planned and what's the breakdown?"*
- *"Give me the full ATC flight plan string."*
- *"What happens to fuel burn if I fly 2000 ft lower?"*
