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
{
"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, or ~/Downloads when cwd is / (Claude Desktop). |
ACCESSO_NO_FILE_OUTPUT | no | Set to 1 where the filesystem isn't the user's (a hosted deployment) so barcodes return inline. |
| Tool | Does |
|---|
accesso_get_order | The order and every admission: product, participant, date, start time, instructions. Returns the slim per-ticket list by default; view: "full" for every parsed field. |
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. |
Nothing here mutates an order. Every tool is read-only except accesso_save_barcodes, which writes PNG files to disk (never overwriting one) unless asked for inline images.

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 / time are 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 into details, 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.
