Open State: Camping — Parks Canada

Part of The Open State, a reference implementation of the Civic Access Protocol. This lets a citizen reach Parks Canada reservations through their own AI assistant, in plain language, while keeping their credentials and their control.

Your services. Your assistant. Your access.

It is a local MCP bundle (.mcpb) you add to your assistant on your own machine. It runs over stdio, searches Parks Canada's public availability, and prepares a booking right up to the payment screen in your own session. It never sees your password or payment details. Session cookies are encrypted on your device; you directly approve consequential actions and pay yourself.

For the binding rules and design, see The Open State: CONSTITUTION.md, AGENTS.md, docs/00-overview.md, docs/01-architecture.md. The verified Parks Canada API contract is in docs/parks-canada-api-findings.md.

What it does

All four Parks Canada booking families — search and book, end-to-end:

Plain-language tools, grouped:

• Search / discovery: search_parks, search_park_availability, search_sites (with a category of campsite / group / accommodation), search_day_use, search_backcountry, get_site_details, list_equipment_types, resolve_dates.
• Account (your session): connect_account opens your own browser to sign in yourself; the session is stored encrypted in a local vault. disconnect_account, connection_status.
• Booking: prepare_booking shows the exact action in a trusted host form, then assembles the cart and drives it to the payment screen only after your approval. You review and pay (Constitution Art. 2).
• Alerts: create_alert / list_alerts / delete_alert — watch a campground and get pinged when a cancellation opens a site.
• Policies: get_reservation_policies — Parks Canada's reservation rules in plain language (fees, change/cancel deadlines and refunds, check-in times, no-shows, and that park entry isn't included). The assistant also surfaces the key deadline and fee right in the booking preview, so you confirm with the terms in front of you.

Accessibility is the point. Where Parks Canada exposes an accessibility attribute, sites are flagged per-site and filterable (accessible_only); output is written to read cleanly with a screen reader (Constitution Art. 3).

Build

Part of the repo-root pnpm workspace: packages/core (provider, booking cart, availability) and packages/bundle (the MCP server + the .mcpb), on @open-state/kit for the session vault and citizen-driven sign-in.

# at the repository root
pnpm install
pnpm -r build

Run (local, stdio)

node packages/bundle/standalone/server.js

The server speaks MCP over stdio and waits for an assistant to connect.

Install from npm

Node.js 20 or newer is required. Configure any stdio MCP client to run:

npx --yes @open-state/camping@1.0.7

For upgrades, change the pinned version and restart the client. To uninstall, remove the MCP client configuration. Local state is intentionally retained; after disconnecting, delete ~/.open-state-camping to remove alerts and all remaining data. See PRIVACY.md.

Install in Claude Desktop (the .mcpb)

Easiest — download the prebuilt bundle. Grab open-state-camping.mcpb from the latest release (tagged camping-v*). In Claude Desktop → Settings → Extensions, install that file and restart. (When upgrading, remove the old version first, then install the new one.)

Or build it yourself from source:

# from the repo root
pnpm --filter @open-state/camping build
pnpm --filter @open-state/camping pack:mcpb

Then install packages/bundle/open-state-camping.mcpb the same way.

Connect it to Claude Code

The repo root ships a .mcp.json that registers the built bundle for Claude Code with a relative path (works for anyone who clones the repo). Build first (pnpm -r build), open the repo in Claude Code, and approve the open-state-camping server when prompted.

Try it

• "Find me a Parks Canada campground in Banff."
• "Any accessible sites at Two Jack Lakeside for the August long weekend, two people?"
• "Find a cabin or oTENTik in PEI for mid-September."
• "Moraine Lake shuttle times for July 17, party of 2."
• "Search Forillon backcountry for Aug 28 — then prepare Lean-to Les Lacs via Le Portage trailhead."
• "Nothing's open — watch it and let me know if a cancellation comes up."
• "What's the cancellation policy if I book a cabin and have to back out?"

To book: ask the assistant to prepare it; it opens your cart at the Parks Canada payment screen, where you sign in (if you haven't via connect_account), review, and pay yourself.

Consequential tools require MCP form elicitation so the host can show the prepared action directly to you. Hosts without it retain anonymous search and read-only tools but intentionally cannot book, update/disconnect an account, or create/delete alerts. See COMPATIBILITY.md.

Alerts

create_alert saves a search and the in-process poller re-checks it on a polite schedule (never faster than every 5 minutes). When a site opens, the watch is retired and — if you gave a notify_target — a short message is sent there.

• Easiest: ask to be notified — the assistant calls create_alert with notify_target="auto", which provisions a private, random ntfy.sh topic (no sign-up), sends a test message, and hands back a subscribe link plus an ntfy:// app deep link.
• Bring your own: pass an http(s) ntfy link you control as notify_target (for safety, links must be on an allowed notification host — not an arbitrary site — to prevent SSRF/open-relay abuse).
• No account, password, or personal information is stored — only the search and the link. An auto topic's random suffix is its secret; treat the link as private, or point OPEN_STATE_NTFY_BASE at a self-hosted ntfy.
• Local limitation: the bundle runs as a local stdio process, so the poller checks only while your assistant is connected to it. The watch persists on disk; notifications fire only while a session is live.

Configuration

All optional, via environment variables:

Tests

pnpm -r test

Tests run fully offline against recorded fixtures — no live network calls. Booking carts are diffed key-for-key against real captured sessions.

Honest notes and known limits

Reality, recorded rather than guessed (Constitution Art. 7):

• Price is not shown. Parks Canada exposes no read-only price; a price only exists as a cart/checkout line item — which is the payment step this tool stops before. You see the price in your own session.
• User-Agent tension. Parks Canada returns HTTP 403 to non-browser User-Agents, so the default UA is browser-like to function. This sits awkwardly with "honest identification" (Art. 7.3); it is configurable and is a candidate for resolution through an official relationship.
• Backcountry availability is a status, not a count — 0 means available (like frontcountry). Booking carts differ by family (site vs quota-zone holds); all are matched to real captured sessions. See the findings doc.

No citizen should be excluded from what is already theirs.
