accessoticketing-mcp
An MCP server for accesso Passport mobile ticket links — the URL a venue emails you after a purchase. Reads the order and every admission on it, the scannable barcodes, and Google Wallet save links.
accesso powers ticketing for a lot of theme parks, water parks, camps, museums and festivals, so one server covers all of them: the merchant is encoded in the link.
Developed and maintained by AI (Claude Code). Use at your own discretion.
What it needs
No login. These links carry their own credential — the oToken in the query
string is what authorises the read. There is no account, no password, no browser
session, and no bot wall.
[!WARNING] That also means the link is a secret. Anyone holding it can view and add the order's tickets. Treat it like a password: don't paste it into issues, logs or chats. This server redacts the tokens from its own output and error messages.
Install
npx -y @chrischall/accessoticketing-mcp
// claude_desktop_config.json / .mcp.json
{
"mcpServers": {
"accessoticketing": {
"command": "npx",
"args": ["-y", "@chrischall/accessoticketing-mcp"],
"env": { "ACCESSO_TICKET_URL": "https://media-engine.na3.accessoticketing.com/tickets/v1/..." }
}
}
}
ACCESSO_TICKET_URL is optional — it just saves passing url on every call. The
server starts fine without it and reports the missing link on first use.
| Variable | Required | Purpose |
|---|---|---|
ACCESSO_TICKET_URL | no | Default ticket link, used when a tool is called without url. |
ACCESSO_OUTPUT_DIR | no | Where accesso_save_barcodes writes PNGs. Defaults to cwd. |
ACCESSO_NO_FILE_OUTPUT | no | Set to 1 where the filesystem isn't the user's (a hosted deployment) so barcodes return inline. |
Tools
| Tool | Does |
|---|---|
accesso_get_order | The order and every admission: product, participant, date, start time, instructions. compact for a slim list. |
accesso_get_ticket | One admission in full, by index. |
accesso_save_barcodes | Writes barcode PNGs and returns paths, or returns the images inline. |
accesso_get_wallet_passes | Google Wallet save links for the tickets. |
accesso_resolve_link | Unwraps an email click-tracking link to the accesso URL it hides. |
accesso_healthcheck | Confirms reachability and whether a default link is configured. |
Every tool is read-only; nothing here mutates an order.

Shell-out skill
Prefer a shell? skills/accesso-tickets/ does the same reading with curl and a
dependency-free parser, no server required. It ships with the package.
Notes on the data
date/timeare the merchant's local wall-clock strings with no timezone attached. They are passed through verbatim rather than converted.- Merchant-specific detail rows (
Guest Number,Web Sales ID, …) are harvested generically intodetails, so a venue this was never tested against still works. - An expired link returns HTTP 200, not an error status — the server detects the body and says the link is expired rather than reporting zero tickets.
