alphaportal-mcp

An MCP server for AlphaPortal (AlphaRoute), the parent/guardian school-bus transportation portal used by districts such as Charlotte-Mecklenburg Schools (cmsnc.alphaportal.app). Ask Claude where your child's bus is, what stops they have, and what arrival notifications came in — and (confirm-gated) adjust notification preferences and walk-zone radius.

Developed and maintained by AI. Use at your own discretion.

What it can do

Reads (all live-verified against the real API):

alphaportal_list_students — your children, with grade, school, and transport flags
alphaportal_get_student — a child's school plus morning/afternoon stops
alphaportal_get_student_stops — assigned stops with times and locations
alphaportal_get_bus_location — live GPS of the bus for the AM or PM run
alphaportal_list_notifications — arrival/departure alerts
alphaportal_list_requests — submitted transportation requests + tracking numbers
alphaportal_get_report_link — a PDF report download link
alphaportal_list_schools, alphaportal_list_grades — district reference data
alphaportal_get_profile, alphaportal_get_account, alphaportal_get_settings
alphaportal_session_status — is a working session configured (no secrets returned)

Writes (confirm-gated — a dry-run of the exact payload unless confirm: true):

alphaportal_edit_walk_radius — set a student's walk-zone radius (meters)
alphaportal_set_notification — set per-student push/email notification preferences

Authentication — the refresh token

AlphaPortal's login is reCAPTCHA-gated and can't be automated with a username/password. Instead this server uses the refresh token the web app stores in your signed-in browser (an 8-day credential); from it, it mints the short-lived access tokens it needs entirely server-side — no browser bridge in the request hot path. There are two ways it gets that token, tried in order:

Automatic (fetchproxy bootstrap). If ALPHAPORTAL_REFRESH_TOKEN is not set, the server reads it once from your signed-in AlphaPortal tab via the Transporter browser extension (the fetchproxy bridge) — a one-shot read that snapshots only the token (a JSON-pointer extraction, so your name/email/ phone never leave the browser), then closes. Requires the extension installed and a signed-in *.alphaportal.app tab. Set ALPHAPORTAL_DISABLE_FETCHPROXY=1 to turn this off.
Manual (env var). Set ALPHAPORTAL_REFRESH_TOKEN yourself. Capture it in a signed-in tab's DevTools console:
```
JSON.parse(localStorage.user).User.RefreshToken
```
This is the right path for a headless/hosted deployment with no browser.

Either way, the server persists each rotated refresh token, so the 8-day window rolls forward as long as you use it at least once every 8 days. If it expires, sign back in (path 1) or re-capture (path 2). The alphaportal-fpx skill under skills/ documents the same capture from a shell via the fpx CLI.

Setup

npm install
npm run build
echo 'ALPHAPORTAL_REFRESH_TOKEN=<paste the token>' > .env
node dist/index.js   # or wire it into your MCP host

.env is gitignored. For an MCP host, set ALPHAPORTAL_REFRESH_TOKEN in its env block (.mcp.json / mcpb user config both reference it).

Optional environment variables

Variable	Purpose
`ALPHAPORTAL_REFRESH_TOKEN`	The refresh token. Optional if the fetchproxy bridge can read it from a signed-in tab; required for a headless/hosted deployment.
`ALPHAPORTAL_DISABLE_FETCHPROXY`	Set to `1` to disable the browser-bridge fallback and require the env var.
`ALPHAPORTAL_SESSION_FILE`	Override the store path (default `~/.alphaportal-mcp/session.json`).

Hosting on mcp-host

mint.yaml describes how to host this server. Note the egress allowlist: the only host the server contacts is api.alpharoute.app (every read/write and the token refresh). On the isolated tier an egress policy is required — allow api.alpharoute.app, or tools report "could not reach the API". A plain hosted registration has no browser bridge, so set ALPHAPORTAL_REFRESH_TOKEN as a secret there.

Development

npm test          # vitest (mocked network)
npm run typecheck # tsc --noEmit (a green vitest run is not a green typecheck)
npm run build     # tsc + esbuild bundle

API shapes are pinned in docs/ALPHAPORTAL-API.md.

Notes & limitations

The transportation-request submission flow (requests/transportation/add, .../alternative/add) is intentionally not exposed yet — its nested request body was not fully captured, and shipping a guessed write payload that submits a real request to the district would be irresponsible. See the docs.
Every request rides your own AlphaPortal session (the refresh token you captured); the server only ever reads your account's data.
