FAA Advisory Circular MCP

An MCP (Model Context Protocol) server that lets you search, retrieve, and track FAA Advisory Circulars (ACs) relevant to airport operations — for both Part 139 certificated commercial service airports and general aviation airports.

What It Does

• Search ACs by keyword, AC number, or topic
• Filter by airport type — Part 139 or GA
• Get full AC details — what it covers, key provisions, what it amends/supersedes, regulatory references
• Direct FAA links to every AC's page and PDF download
• Bookmark and track ACs with your own notes per airport
• Export summaries as printable markdown (optionally saves to a folder you specify)
• Persistent memory — airport profile and bookmarks are stored locally in data/

Configuration in Claude Code / CoWork

Add to your Claude Code MCP config (claude_desktop_config.json or via settings):

{
  "mcpServers": {
    "faa-advisory-circular": {
      "command": "node",
      "args": ["C:/Users/paris/Desktop/faa-advisory-circular-mcp/dist/index.js"]
    }
  }
}

Memory & File Storage

• Airport profile and bookmarks are stored in data/profile.json and data/bookmarks.json — they persist between sessions automatically.
• In CoWork or any session with a save folder configured: use set_airport_profile with a save_folder path, and export_circular_summary / export_bookmarks will also write .md files to that folder — ready to print or open in Word.
• In chat without a folder: exports return as text in the conversation. Everything still lives in the data/ directory for next time.
