MCP server for read-only American Airlines AAdvantage account access

Read-only access to American Airlines AAdvantage account information and rewards status.

aa-mcp-server

An MCP server that gives Claude (or any MCP-compatible LLM) read-only access to your American Airlines AAdvantage account — mile balance, Loyalty Points progress, transaction history, upcoming trips, travel credits, and partner offers.

This is not a browser-automation wrapper. The server discovers and calls aa.com's underlying JSON APIs directly using session cookies extracted from a Chromium login. All HTTP traffic uses curl_cffi with Chrome TLS impersonation to satisfy aa.com's Akamai Bot Manager.

Setup

bash

pip install aa-mcp-server

One-time auth

aa.com is fronted by Akamai Bot Manager — you can't log in via headless requests. The flow:

Launch a real Chromium with a persistent profile and a remote-debugging port:

bash

aa-auth-browser              # default account
aa-auth-browser personal     # named account

Log into aa.com (and complete 2FA if prompted) in the window that opens.
Copy the cookies into the MCP store:
bash
```
aa-mcp-server --extract-session default
```
Or call the save_session_from_browser MCP tool from Claude.

The cookies live in ~/.aa-mcp/accounts/<account>/session.json. The chromium profile lives in ~/.aa-mcp/chrome-profiles/<account>/. To refresh after expiry, relaunch aa-auth-browser (the saved profile auto-refreshes the access_token cookie when you visit any aa.com page) and re-run --extract-session.

AA_MCP_CHROMIUM=<path-to-chrome.exe> overrides the auto-discovery if your Chromium is somewhere unusual.

Multi-account

Every tool takes an optional account parameter. Omit it to use the default account.

python

get_account_summary()                # default
get_account_summary(account="spouse")

Running

bash

aa-mcp-server                        # stdio transport
aa-mcp-server --setup                # show account status & setup hints
aa-mcp-server --extract-session NAME # save cookies from running Chromium

Add to your MCP client config (e.g. Claude Desktop):

json

{
  "mcpServers": {
    "aa": {
      "command": "aa-mcp-server"
    }
  }
}

Limitations

Read-only. No booking, no award redemption, no profile edits.
Cookie expiry. The access_token JWT lives ~45 min; the refresh_token cookie typically ~30 days. Visiting any aa.com page in the saved Chromium profile silently refreshes both. After a long gap, re-extract.
GraphQL coverage. Only the GetCustomer persisted query is wired up. Expanding requires capturing additional sha256Hashes from the browser bundle — easy but a per-feature task.
One region tested. All testing has been on US-locale aa.com. International locales may require different referer paths.
