mcp-route-master

An MCP server that helps travellers in India find the right intercity bus, book it on the official site, and avoid booking scams. It works with Claude, ChatGPT, Gemini and any other MCP client, it is free to run, and it needs no API keys.

You: "Dehradun to Varanasi tonight, sleeper"
AI + route-master: finds the buses on redBus/MakeMyTrip, ranks them, checks the operator,
  shows the seat map, fills the form with your OK, checks everything, and hands you a
  "Pay here" link on the official site.
You: pay.

Hosted server: https://mcp-route-master.onrender.com/mcp. Add it to Claude, ChatGPT or Gemini in a minute, see Connect to the hosted server.

How it works

route-master never opens booking websites itself. Booking sites forbid scraping, block bots, and the payment must happen in a browser you control. So the work is split three ways:

            ┌────────────────────────── your computer ──────────────────────────┐
  You  ───► │  AI app (Claude, ChatGPT, Gemini…)  ──clicks/reads──►  your browser │ ──► redbus.in /
            │        │   ▲                                         (official site)│     makemytrip.com
            │  tools │   │ answers, scripts, checks                                │
            │        ▼   │                                                         │
            │   route-master (this server: knowledge + checks, no network calls) │
            └────────────────────────────────────────────────────────────────────┘

Works with Claude, ChatGPT and Gemini

Quickest start: add https://mcp-route-master.onrender.com/mcp to your AI app, see Connect to the hosted server.

Every app gets the same links, ranking, operator and scam checks, seat maps and the pre-payment check. Only apps that can control your browser can do the clicking; everywhere else you click and route-master tells you exactly what to do. Setup guides: docs/chatgpt.md, docs/gemini.md, docs/remote_http.md.

What it can do

• Find buses. Dated links that open your route and date on redBus, MakeMyTrip and Goibibo (plus AbhiBus, Cleartrip, FlixBus, IRCTC Bus). About 260 places with aliases (Bangalore/Bengaluru, Banaras/Varanasi) and bus stands (Kashmiri Gate → Delhi).

• Rank them. Trust (government operator vs copycat, rating weighted by review count, live tracking, highway pickups), fit (a "semi-sleeper" is a reclining seat, not a bed; seater/sleeper buses need a berth), price, seats left, buses already gone, closeness to your preferred time.

• Spot scams. Look-alike domains (redbus-pay.in, makemytrip.com.offer.in), payments to personal UPI IDs, OTP/PIN requests, refund and remote-access tricks, with the 1930 / cybercrime.gov.in line.

• Show seats. A text seat map (decks, aisle, window, sold, women/men-only) and suggestions ("a lower single berth near the front").

• Book in your browser. Step-by-step script with stop points, ready-made browser actions, automatic reading of each page, a pre-payment check, and a final Pay here link.

Tools

All 12 tools are read-only: they never book, pay or store anything, and answer in well under a second.

page_action + read_page (added in v0.5.0) mean the AI no longer writes its own page-reading code: it runs route-master's capture script, passes the result back, and gets the finished answer. A few clicks only work as real clicks (redBus bus cards, MakeMyTrip's last button): there the script marks the element as rm-target and the AI clicks it.

Resources, templates and prompts

For MCP clients that show them (Claude Desktop, Claude Code, MCP Inspector, …). Chat apps that don't support them simply ignore them; everything is also reachable through the tools.

Prompts

A booking, step by step

What happens when you ask "book a sleeper from Dehradun to Varanasi tonight" in Claude Desktop (tested live on 2 Nov 2026):

1. plan_bus_trip → the AI opens the dated redBus link.

2. page_action(capture) → read_page → ranked list (here: one bus, Tiwari and Brothers 17:00).

3. check_operator → 70/100, 4.5★ from 72 ratings, live tracking.

4. page_action(open_bus) → real click → read_page → seat map. You pick a berth (3U).

5. page_action(select_seats) → page_action(continue) → read_page → numbered stops. You pick boarding and drop points.

6. You agree to your details being typed; the AI types them and asks about each paid extra; page_action(decline_addons) for the ones you refused.

7. read_page on the form → booking summary. You reply "confirm".

8. page_action(continue) → payment page → read_page → one message:

   Total: ₹3,673.95 · seat held about 7 min Pay here (redbus.in): https://www.redbus.in/paymentDetails

9. You pay. The ticket arrives by SMS/email.

Connect to the hosted server

route-master is live at:

https://mcp-route-master.onrender.com/mcp

Streamable HTTP, no sign-in, no API key. All 12 tools are read-only. Health check: https://mcp-route-master.onrender.com/health.

First call can be slow. It runs on Render's free plan, which sleeps after about 15 minutes idle. The first request then takes up to a minute; if the app reports a timeout, ask again.

Claude (claude.ai, Desktop, mobile)

1. Open claude.ai → Customize (or Settings) → Connectors.

2. Click Add custom connector.

3. Name: route-master · URL: https://mcp-route-master.onrender.com/mcp · leave the OAuth fields empty → Add.

4. In a chat, open the + / tools menu and make sure route-master is switched on.

A connector added on claude.ai also appears in Claude Desktop and the mobile apps. The Free plan allows one custom connector; Pro, Max, Team and Enterprise allow more (on Team/Enterprise an Owner adds it under Organization settings → Connectors). In Claude Desktop with its built-in browser (or Claude in Chrome), Claude opens redBus/MakeMyTrip, reads each page with route-master and does the clicking up to the payment page.

Claude Code

claude mcp add --transport http route-master https://mcp-route-master.onrender.com/mcp

Check with claude mcp list (or /mcp inside Claude Code).

ChatGPT

1. ChatGPT on the web → Settings → Apps (called Apps & Connectors or Connectors in some versions) → Advanced settings → turn on Developer mode.

2. Back in Apps, click Create (or + / Add), then:

   • Name: route-master

   • MCP server URL: https://mcp-route-master.onrender.com/mcp

   • Authentication: No authentication (None)

   • Tick "I trust this application" → Create.

3. In a new chat, open + → Developer mode (or More → route-master) and select route-master for that chat. Turning it on in Settings alone isn't enough.

4. Ask: "Use route-master: sleeper bus Delhi to Dehradun tonight."

OpenAI documents developer mode for Plus, Pro, Business, Enterprise and Education; our test also worked on a Free account, but menus and availability change. ChatGPT can't control your browser, so it works in paste mode: open the link route-master gives, select all and copy the results page, paste it into the chat, and route-master ranks the real buses (rank_pasted_results). Then it gives you step-by-step instructions to finish on the site (booking_steps). More in docs/chatgpt.md.

Gemini app (gemini.google.com)

1. On the web (gemini.google.com) → Settings → Connected apps.

2. Under Custom apps, click Add a custom app, paste https://mcp-route-master.onrender.com/mcp → Next → approve.

3. In a chat, mention it: "@route-master sleeper bus Delhi to Dehradun tonight".

Custom apps can only be added from the web app (they then show on mobile too), and for now only in English and for some accounts. Like ChatGPT, Gemini works in paste mode: copy the results page from the link and paste it in. Gemini sometimes answers from its own knowledge instead of calling the tools; if the answer has no route-master links or tables, say "use the route-master tools only". More in docs/gemini.md.

Gemini CLI

gemini mcp add --transport http route-master https://mcp-route-master.onrender.com/mcp

Or add this to ~/.gemini/settings.json (Windows: %USERPROFILE%\.gemini\settings.json):

{
  "mcpServers": {
    "route-master": { "httpUrl": "https://mcp-route-master.onrender.com/mcp", "timeout": 60000 }
  }
}

Run /mcp inside Gemini CLI to see the tools; the prompts (find_bus, book_bus, check_scam) appear as slash commands. A copy is in examples/gemini_cli_remote.json.

Any other MCP client

Use transport Streamable HTTP and URL https://mcp-route-master.onrender.com/mcp (no headers). To test without an AI:

npx @modelcontextprotocol/inspector

then choose Streamable HTTP, paste the URL, Connect → List Tools (12 tools).

If it doesn't work

Signed-in mode: the Chrome extension

With the route-master Chrome extension, any AI app (Claude, ChatGPT, Gemini) can book in your own Chrome while you only chat. The AI picks nothing on its own: you choose the bus, seat and stops, and you pay yourself. Setup and details are in route-master-extension/README.md.

1. Install the extension (Load unpacked) and Sign in with Google.

2. Add /app/mcp as a connector in your AI app and sign in with the same Google account.

3. Chat. Every step is one tool call that returns what the page now shows:

   • browser_open: ranked buses;

   • browser_action with open_bus, select_seats, choose_points, decline_addons or continue;

   • browser_fill and browser_choose: the passenger form, after you agree;

   • the final continue: only after you "confirm" a problem-free summary; the payment page then opens in front for you.

How the server finds your browser: the connector's sign-in and the extension's sign-in carry the same Google account ID. The extension keeps a live WebSocket to /ext/ws, and the server sends each step to that connection.

Run it yourself

To run your own copy, locally or on your own host.

Needs Python 3.10+ and uv. Until the package is on PyPI, point uvx at this folder (replace the path with yours). After publishing, use "args": ["mcp-route-master"].

Without uv: pip install -r requirements.txt && pip install -e ., then use "command": "mcp-route-master" (no args) in the configs below.

Claude Desktop, local (free plan works)

Settings → Developer → Edit Config, then add to claude_desktop_config.json:

{
  "mcpServers": {
    "route-master": {
      "command": "uvx",
      "args": ["--from", "C:\\Users\\LENOVO\\Desktop\\TechnocratIQ\\myProject\\mcp-route-master", "mcp-route-master"]
    }
  }
}

Restart Claude Desktop after every update. See examples/claude_desktop_config.json. For assisted booking, use Claude's built-in browser (or Claude in Chrome).

Gemini CLI, local (free)

Add the same block to ~/.gemini/settings.json (Windows: %USERPROFILE%\.gemini\settings.json). See examples/gemini_settings.json; for a remote server, examples/gemini_cli_remote.json. Type /mcp in Gemini CLI to see the tools; the prompts appear as slash commands. More in docs/gemini.md.

Claude Code (local)

claude mcp add route-master -- uvx --from "C:\Users\LENOVO\Desktop\TechnocratIQ\myProject\mcp-route-master" mcp-route-master

Your own remote server (for ChatGPT, claude.ai and the Gemini app)

These run in the cloud, so they connect only to a public HTTPS URL (Streamable HTTP at /mcp).

1. Get a URL.

   • Quick test: run uvx --from . mcp-route-master --transport http --port 8000 and cloudflared tunnel --url http://127.0.0.1:8000, then set MCP_ALLOWED_HOSTS=<the trycloudflare host>.

   • Permanent: deploy the Dockerfile. Render: render.yaml is a ready Blueprint, see docs/render.md. deploy/ has templates for Fly.io (Mumbai region) and Google Cloud Run. The server listens on $PORT and has a /health check.

2. Add https://<your-host>/mcp:

   • ChatGPT: turn on developer mode (paid plans) and create an app/connector with authentication None. See docs/chatgpt.md.

   • Gemini app: Settings → Connected apps → Custom apps → Add a custom app. Availability is limited (English, personal accounts). See docs/gemini.md.

   • claude.ai: Settings → Connectors → Add custom connector.

3. Optional protection:

   • MCP_AUTH_TOKEN makes clients send Authorization: Bearer …. Use it for Gemini CLI/API and scripts; ChatGPT and the Gemini app can't send a fixed token.

   • For those two, use a hard-to-guess --path instead.

   • MCP_CORS_ORIGINS allows browser-based clients.

Host it on Prefect Horizon (FastMCP's hosting, free for personal projects)

Push this folder to GitHub, sign in at horizon.prefect.io with GitHub, pick the repo and set Entrypoint horizon_app.py:mcp with Authentication off (needed for ChatGPT and the Gemini app). You get https://<server-name>.fastmcp.app/mcp, and every push to main redeploys. horizon_app.py makes the src/ package importable on the host.

Try it without an AI

npx @modelcontextprotocol/inspector uvx --from . mcp-route-master

Compatibility notes

• Tool input schemas avoid anyOf, null and $ref, so Gemini accepts them; outputs are plain text (works in every host).

• Every tool is annotated readOnlyHint: true, destructiveHint: false, openWorldHint: false (it changes nothing and calls no outside service), which is what ChatGPT reads to decide whether to ask before running a tool.

• search / fetch follow the standard shapes ChatGPT uses for knowledge sources and deep research.

• Fully asynchronous: every tool, resource and prompt is async; large page captures are parsed in a worker thread so one request never blocks others on a shared remote server.

• Both the legacy and current MCP protocol versions are tested (2024-11-05, 2025-03-26, 2025-06-18).

Configuration

mcp-route-master --version and --show-data-dir print the version and the data folder.

Supported sites

* marks the element for a real click (the site ignores scripted clicks there).

What the live tests taught (and the server now handles):

• redBus: guest checkout, no login. In a narrow window it shows its mobile layout (tap the bus card; "Fill passenger details" after choosing stops). It may pre-fill State of Residence and remember contact details; WhatsApp updates can start on or off. Results load as you scroll (only while the browser pane is visible). The list price ("₹2,199 onwards") is a seat; berths cost more. The payment page adds 5% GST and holds the seat for about 8 minutes.

• MakeMyTrip: guest checkout. The seat map has no numbers until a seat is clicked, so seats are labelled by position (L1, U3…) and the site's own number ("B") is used after selecting. Its data-testid can say "available" for greyed (sold) berths; the grey look wins. The last CONTINUE ignores scripted clicks. Email is required; Free Cancellation is priced per person.

• Pickup point sets the departure time (20:30 at the office, 20:50 at the mall), and many drops are highway stops (toll plazas, petrol pumps), which route-master flags.

If a site changes its layout, read_page says what it couldn't read and the AI falls back to reading the page itself.

Safety and privacy

• Never automated: logging in, creating accounts, OTPs, passwords, UPI PIN, card details, payment. The scripts never type personal details; the AI types them only after you agree.

• Approval gate: the AI goes to payment only when the latest booking_summary has no problems and you reply confirm to it. If the page changed, it shows a new summary and asks again.

• Payment hand-over check: if the payment total is more than the confirmed fare plus about 5% tax, the hand-over says so instead of calling it ready.

• Official sites only: read_page accepts only redbus.in and makemytrip.com pages (exact host match, look-alikes rejected); booking links and checkout pages are checked against official domains.

• The capture script reads only the open tab and returns it to the AI. On payment pages it keeps only the summary text and never reads input fields. Password fields are never read.

• No storage: passenger details pass through the AI and this server only for the current step; nothing is saved or logged. The only file written is the optional list of unknown place names (pending_locations.json), which never contains personal data.

• No scraping, no bypassing: route-master never fetches booking sites and never works around bot checks; if a site ignores a click, the user is given the link to press it.

Development

With uv:

uv sync                                  # creates .venv with dev tools
uv run pytest                            # 397 tests
uv run ruff check . && uv run ruff format --check .

With pip:

python -m venv .venv && source .venv/bin/activate     # Windows: .venv\Scripts\activate
pip install -r requirements-dev.txt -e .
pytest

tests/browser/ runs the browser scripts in real Chromium. It needs Node.js and its playwright package (npm i -g playwright && npx playwright install chromium) and is skipped automatically without them.

Adding support for a page layout: capture the page with route-master://scripts/capture.js (or page_action(capture)), add the JSON to tests/fixtures/page_fixtures.py, extend the parser in browser/pages.py, and add a test in tests/unit/test_pages.py.

Places, booking-site IDs and link formats

Places live in src/mcp_route_master/data/hubs.json: about 260 hubs with aliases, bus stands and boarding areas (which resolve to the parent city).

• Unknown places are counted in pending_locations.json in the data folder (mcp-route-master --show-data-dir). It's a review list only and never changes results.

• To add a place or ID locally, create locations.json in the same folder, same format:

  {"hubs": [{"name": "Kasol", "state": "Himachal Pradesh", "aliases": ["kasol village"]}],
   "routes": {"abhibus": {"Delhi|Kasol": 1234}}}

• Check IDs on the live site first. A wrong ID shows no error, just "0 buses" or another date. Tip: https://www.redbus.in/bus-tickets/{from}-to-{to} redirects to a URL containing both city IDs.

redBus IDs filled in so far: Delhi, Manali, Bengaluru, Hyderabad, Dehradun, Prayagraj, Varanasi. Government operator websites in operators.json are listed only when confirmed on a government source; the safety checker treats those domains as official.

Limitations and roadmap

• No live data without a browser. The server doesn't fetch seats or fares. For full automation without a browser, the path is a licensed partner API (redBus SeatSeller, MakeMyTrip/Goibibo affiliate, FlixBus partner) plus a hosted backend.

• Two sites automated. read_page/page_action cover redBus and MakeMyTrip; other sites get links. Site layouts change; the parsers are tested on recorded pages and report what they couldn't read.

• Few routes have every ID. Other routes get MakeMyTrip dated links plus homepages.

• Pattern-based safety checks. "No red flags" is not a guarantee; phone numbers can't be verified offline.

• Planned: suggesting a change at a nearby hub when a route has few or no direct buses; more redBus/Goibibo city IDs.
