Office Booking

A small, personal Model Context Protocol server and command-line tool that books and cancels your office cab and lunch from inside VS Code (or any MCP client) — or fully on autopilot — by wrapping the same APIs the company apps already use with your own logged-in account.

⚠️ Use responsibly. This only replays requests your own authenticated account is allowed to make. Don't share captured tokens, don't automate other people's accounts, and check your company's acceptable-use policy before relying on it. It is not affiliated with or endorsed by the app vendors.

What you get

Two ways to drive it:

• MCP server — ask an LLM agent (e.g. Copilot Chat) in plain English: "book lunch for next Wednesday", "cancel Friday", "list my cab trips".
• CLI (office-booking …) — the same actions from the terminal, also understands natural-language dates (book "next wednesday", book "this week").

Core tools:

Tool	What it does
list_cab_bookings	Show your current/upcoming cab trips
book_cab	Book a cab
cancel_cab	Cancel a cab trip
list_lunch_bookings	Show your lunch bookings
book_lunch	Book lunch for a date
cancel_lunch	Cancel a lunch booking

Hands-off extras (lunch):

• 📅 Attendance schedule — encode your rotating hybrid pattern (e.g. a 3-day week alternating with a 2-day week); it books only the days you're actually in.
• 🏖️ Outlook leave detection — reads your Outlook calendar and skips any day marked Out of Office or titled like leave/PTO/vacation.
• 📧 Daily QR delivery by email — emails you the day's lunch QR, then deletes it again in the evening via IMAP so your inbox stays clean.
• 💻 Wake-triggered auto-booking — a macOS launchd job books every upcoming office day inside the cafeteria's advance window whenever your Mac is awake (no fixed alarms; idempotent, so it just tops up what's missing).

The endpoints are not hard-coded to your company — the project ships with placeholder paths/payloads marked TODO. You fill them in once, using the traffic you capture in Step 1.

Step 1 — Capture the APIs

✅ Easiest path first: use the web app. If your cab/lunch service has a web portal, capture it there — open the site in your browser, press F12 → Network tab, perform each action once, and copy the requests (right-click → Copy as cURL). There's no certificate setup and no TLS pinning to fight, so it's dramatically simpler than intercepting a phone. The project even ships a curl_to_config helper to turn a pasted cURL command into config. Only fall back to the mobile-proxy steps below if there is no web version.

If the service is mobile-only, intercept its HTTPS traffic with a proxy. mitmproxy is free and works well.

1a. Install + start mitmproxy

brew install mitmproxy        # macOS
mitmweb                       # opens a web UI at http://127.0.0.1:8081

mitmproxy listens on port 8080 by default.

1b. Point your phone at the proxy

1. Put your phone and Mac on the same Wi-Fi.
2. Find your Mac's IP: ipconfig getifaddr en0.
3. On the phone: Wi-Fi → (your network) → Configure Proxy → Manual, server = your Mac IP, port = 8080.

1c. Install mitmproxy's CA certificate on the phone

1. On the phone's browser open http://mitm.it and install the cert for your OS.
2. iOS: Settings → General → VPN & Device Management → install the profile, then Settings → General → About → Certificate Trust Settings and toggle it on. (Both steps are required.)
3. Android: install under user certificates (system store needs root).

1d. The TLS-pinning gotcha ⚠️

Many corporate apps use certificate pinning and will refuse to connect while proxied — you'll see connection errors in the app and TLS errors in mitmproxy.

Things to try, in order of effort:

• Check if there's a web version (the recommended path — see the tip at the top of Step 1). Capturing the web portal in browser DevTools avoids pinning entirely and is by far the easiest option.
• See whether the app still works for some calls (login may be pinned but booking may not).
• On a rooted Android / jailbroken iOS you can disable pinning with Frida + objection, but that's advanced and may violate device/app policy — only do it on a device you own and are allowed to modify.

If pinning fully blocks you, the web portal route is by far the most practical.

1e. Record each action

With capturing live, perform each action once in the app: list trips, book a cab, cancel it, list lunch, book lunch, cancel it. For each captured request note:

• Host (e.g. cab-api.yourcompany.com) → goes in *_API_BASE_URL
• HTTP method + path (e.g. POST /api/v1/trips)
• Auth header (e.g. Authorization: Bearer eyJ...) → token goes in *_AUTH_TOKEN
• Any extra header like x-api-key → *_API_KEY
• The request body (JSON) and the response body

---

Step 2 — Fill in the endpoints

Open these two files and replace the TODO placeholders with what you captured:

• src/office_mcp/cab_client.py
• src/office_mcp/lunch_client.py

You're adjusting three things per method: the HTTP method, the path, and the JSON field names. The auth headers are handled centrally in src/office_mcp/http_client.py (_default_headers) — tweak there if your app doesn't use Authorization: Bearer.

---

Step 3 — Configure secrets

cp .env.example .env

Fill in the base URLs and tokens you captured. .env is git-ignored, so your tokens stay local.

🔑 Tokens often expire. When a tool starts returning HTTP 401, re-capture a fresh token and update .env.

---

Step 4 — Install & run

python3 -m venv .venv
source .venv/bin/activate
pip install -e .

Sanity-check it starts (Ctrl-C to stop):

python -m office_mcp.server

---

Step 5 — Use it in VS Code

This repo includes .vscode/mcp.json, so VS Code will offer to start the office-booking server. Open the Copilot Chat Agent mode, and you can ask things like:

• "List my cab bookings."
• "Book a cab from Home to Office tomorrow at 9:30am."
• "Cancel lunch order 12345."

Enable debug logging by setting OFFICE_MCP_DEBUG=true in .env to see the exact outgoing requests in the server's stderr.

---

Step 6 — (Optional) CLI & hands-off automation

The same actions are available from the terminal via the office-booking command (installed by pip install -e .):

office-booking lunch list
office-booking lunch book "next wednesday"     # natural-language dates
office-booking lunch cancel <order-id>
office-booking lunch qr 23-06-2026             # generate a booking's QR

Lunch automation commands:

office-booking schedule set      # record your rotating office-attendance pattern
office-booking lunch auto-book    # book upcoming office days in the advance window
office-booking lunch qr-deliver   # email today's QR to yourself
office-booking lunch qr-cleanup   # delete that QR email via IMAP

These are designed to run unattended on macOS via launchd agents (~/Library/LaunchAgents/com.officebooking.*.plist):

• auto-book — runs whenever the Mac wakes (RunAtLoad + a periodic StartInterval); idempotent, so it simply books any still-unbooked office day inside the cafeteria's advance window and skips leave days.
• qr-deliver / qr-cleanup — fixed weekday times; if the Mac is asleep at the scheduled time, launchd runs the missed job shortly after the Mac wakes.

All of these honour the attendance schedule and Outlook leave detection, so you only ever get booked for days you're actually in the office.

Security notes

• Secrets live only in .env (git-ignored) — never commit real tokens.
• The server makes outbound calls only to the hosts you configure.
• If you push this to a repo, double-check no capture files (captures/, *.flow), .env, or personal data (office_schedule.json, QR PNGs) slipped in. The included .gitignore already excludes all of these.
