PassNinja

io.github.flomioPublished by GitHub account flomiov0.4.0Updated Oct 24, 2026

Issue and manage Apple Wallet & Google Wallet passes from any MCP-aware AI client.

Overview

AI-generated overview

PassNinja lets an assistant issue and manage Apple Wallet and Google Wallet passes, pass templates, webhooks and scan-event readers through the PassNinja API.

What you can do
List, inspect, create, update and delete pass templates, including required fields and reader configuration (template creation and deletion are enterprise only). Issue, list, read, update, delete and decrypt individual passes, and fetch raw pass data. Manage webhooks: create, list, get, delete and read delivery results. Manage scan-event applications and readers, including reader tokens and merged reader configuration. Check the active credential and account with a whoami tool.
When to use it
Useful when you want to drive PassNinja wallet pass workflows from a chat client, for example listing templates, counting installed passes, or issuing a pass for a given email, without switching to the CLI or dashboard.
Requirements
Runs as a local process over stdio, installed as a desktop .mcpb bundle (macOS, Linux amd64, Windows amd64) or launched as the passninja mcp command from any MCP client. Needs a PassNinja API key and account ID, supplied through the install dialog, the PASSNINJA_API_KEY and PASSNINJA_ACCOUNT_ID environment variables, flags, or a saved auth file. Network access to the PassNinja API is required.
Before you install
Holds account credentials: the API key and account ID are stored in a local auth file or environment variables. Many tools write or delete data, including creating and deleting passes, templates, webhooks, applications and readers. Template and webhook operations are enterprise-only and scan-event features are premium, so plan limits apply. Reader tokens and webhook bearer tokens are shown only once at creation. Reader hosts should use a reader token rather than the account API key.

Installation

In SourceWeft

  1. Open PassNinja in the dashboard and add it to a workspace.
  2. Enable the server for the chats that should use its tools.

Desktop only via STDIO. STDIO servers start a local process, so they need the SourceWeft desktop host.

Other MCP clients

Follow the launch instructions in the repository.

README

passninja

Command-line interface for the PassNinja REST API. Wraps /v1/pass_templates, /v1/passes, and /v1/webhooks so you can manage Apple Wallet and Google Wallet passes from the shell.

Install

macOS / Linux (Homebrew)

sh
brew tap flomio/passninjabrew install passninja

Windows (PowerShell)

powershell
irm https://github.com/flomio/passninja-cli/releases/latest/download/install.ps1 | iex

From cmd.exe:

cmd
powershell -ExecutionPolicy Bypass -Command "irm https://github.com/flomio/passninja-cli/releases/latest/download/install.ps1 | iex"

The script detects your CPU (amd64, arm64, or 386), downloads the matching binary from the latest GitHub release, verifies its SHA256, drops it in %LOCALAPPDATA%\Programs\passninja\, and adds that directory to your user PATH. No admin needed; re-running upgrades in place.

Pin a specific version, or override the install directory:

powershell
$env:PASSNINJA_VERSION = 'v1.2.3'$env:PASSNINJA_INSTALL_DIR = 'C:\tools\passninja'irm https://github.com/flomio/passninja-cli/releases/latest/download/install.ps1 | iex

Windows (Scoop)

If you already use Scoop:

powershell
scoop bucket add flomio https://github.com/flomio/scoop-passninjascoop install passninja

Claude Desktop (one-click .mcpb install)

For chat-driven pass workflows, install the PassNinja MCP server into Claude Desktop:

  1. Download passninja.mcpb from the latest release.

  2. Double-click the file. Claude Desktop opens an install dialog showing the 31 tools the server exposes (pass templates, issued passes, webhooks, scan-event applications and readers).

  3. The dialog prompts for your API key and account ID — get them at https://www.passninja.com/settings → API key.

  4. Hit Install, restart Claude Desktop, then ask Claude things like:

    List my passninja pass templates and tell me how many passes are installed on each.

    Issue a new pass on ptk_0x002 for [email protected].

The bundled binary is code-signed with Apple Developer ID and notarized, so macOS Gatekeeper accepts it without prompts. Same .mcpb works on macOS (universal), Linux (amd64), and Windows (amd64).

The server is also listed in the official MCP Registry as io.github.flomio/passninja-cli, so any MCP client that consumes the registry can discover and install it automatically.

Authenticate

sh
passninja auth# Pastes your API key and account ID; verifies by hitting /v1/pass_templates# and saves credentials to ~/.passninja-auth.json (0600).

Or pass credentials via env / flags:

sh
export PASSNINJA_API_KEY=...        PASSNINJA_ACCOUNT_ID=aid_0x002passninja --api-key=... --account-id=... pass-template list

Flag > env > ~/.passninja-auth.json > ~/.passninja.yaml > defaults.

The same precedence applies to the MCP server: passninja mcp (started by Claude Desktop and other MCP clients) reads PASSNINJA_API_KEY / PASSNINJA_ACCOUNT_ID from its environment, falling back to the auth file.

Stdio MCP server

The CLI also doubles as a Model Context Protocol server. The .mcpb install above wires this into Claude Desktop, but you can hook it into any MCP client (Cursor, Cline, Zed, etc.) by configuring the client to launch:

passninja mcp

Tool surface (snake_case names mirror the CLI subcommands):

whoamipass_template_{list, get, required_fields, reader_config, create, delete}pass_{list, get, create, update, delete, raw, decrypt}webhook_{list, get, create, delete, results}

Each tool's input schema, destructive-hint annotations, and rich descriptions let the LLM self-discover correct usage without external documentation.

Webhook events

The CloudEvents 1.0 type taxonomy emitted by passninja-site:

Event typeWhen it fires
pn.pass.installedFirst device installs an issued pass
pn.pass.updatedPass fields change via PATCH/PUT
pn.pass.uninstalledLast device removes the pass
pn.pass.scannedA reader records a scan event (carries scanId, readerSerial, result)

Reserved for future use: pn.pass.issued, pn.pass.deleted, pn.pass_template.created, pn.pass_template.updated, pn.pass_template.deleted.

Running a reader host

Cloud-connected readers (VTAP Cloud, Famoco Tap&Go) post scans to PassNinja themselves. A simple reader — Reyax RYRR30D, ACS WalletMate, Elatec TWN4 — has no cloud connection of its own, so reader serve supplies one: it takes the values the reader captures, submits them as scan events, and applies the LED/beep instruction the server returns.

Setup is three steps, and only the last one runs on the reader host:

sh
# 1. an application decides what a scan means for one pass templatepassninja application create --name "Front gate" --kind validate \  --pass-template ptk_0x216 --rescan-window 14400
# 2. a reader binds to it; the token is printed once — save itpassninja reader create --name "Front gate" --location "Gate 2" \  --application app_0x1
# 3. on the reader host (a Raspberry Pi, a kiosk PC, …)passninja reader serve --token rdr_... --pcsc         # attached PC/SC readermy-reader-daemon | passninja reader serve --token rdr_...   # or any daemon

serve authenticates as that one reader with its bearer token — a reader host never needs, and should never hold, your account API key.

Tap values arrive from one of three sources:

  • --pcsc drives an attached PC/SC contactless reader (ACS WalletMate / WalletMate II, incl. the Mini module) directly — no separate daemon. The host runs the wallet flows itself: on an Apple tap it captures the VAS cryptogram; on an Android tap it has the server pre-sign the Smart Tap session mid-tap (the collector key never leaves PassNinja), negotiates the secure channel, and captures the encrypted bundle. Both are submitted for server-side decryption — the host holds no key material. First-generation WalletMates ship with RF polling disabled; serve enables it automatically when the vendor CCID driver is installed. Needs a native (cgo) build on macOS/Linux — go install and Homebrew builds qualify.
  • stdin (one value per line) — pipe any reader daemon's output in.
  • --listen 127.0.0.1:8080 — a loopback HTTP endpoint a driver POSTs to.

For stdin/HTTP, a value that looks like raw captured APDUs is forwarded for server-side decryption; anything else is treated as an already-decrypted pass serial.

Each result is one JSON object on stdout:

json
{"scanId":"9f8e7d6c-…","result":"accepted","pass":{"passTemplate":"ptk_0x216","passId":"fee4a257185906b92a"}, "readerInstructions":{"success":true,"led":"green","beep":true,"message":"Accepted"}}

To drive a physical LED, use the outcome hooks — they receive $PN_RESULT, $PN_LED, $PN_MESSAGE, $PN_PASS, $PN_SCAN_ID, and — when a forward application answered — $PN_FORWARD_BODY (the endpoint's JSON reply). On a forward application, $PN_MESSAGE is the endpoint's message verbatim and the printed scan JSON carries the reply under forwardResponse:

sh
passninja reader serve --token rdr_... \  --on-accept 'gpioset 0 17=1' --on-reject 'gpioset 0 27=1'

Heartbeats (default every 5m) report liveness plus the hardware identity you pass with --serial / --manufacturer / --model / --firmware, which is what fills in the reader's Hardware panel in the dashboard. Readers whose vendor MDM already tracks them should use --no-heartbeat.

passninja webhook create returns the bearer token once on creation. Save it — it will not be shown again.

Build from source

sh
git clone https://github.com/flomio/passninja-cli.gitcd passninja-climake build                 # writes dist/passninja./dist/passninja versionmake install               # installs to $GOPATH/bin

Release flow

Tag-driven. Push a vX.Y.Z tag on master; the GitHub Actions workflow at .github/workflows/release.yml matrix-builds darwin/linux × arm64/amd64, packages a code-signed + Apple-notarized passninja.mcpb on a macOS runner, publishes both the binaries and the .mcpb on the GitHub Release, and opens a PR against flomio/homebrew-passninja bumping the formula url and sha256.

Apple credentials live in repo secrets (APPLE_TEAM_ID, APPLE_API_KEY_ID, APPLE_API_ISSUER_ID, APPLE_SIGN_IDENTITY, APPLE_CERTIFICATE_PASSWORD, plus the base64-encoded APPLE_API_KEY_P8 and APPLE_CERTIFICATE_P12).

After each tagged release, the MCP Registry entry needs a refresh. Bump packages[0].identifier, packages[0].version, packages[0].fileSha256, and the top-level version in server.json to match the new release, then:

sh
mcp-publisher login github      # one-time per machinemcp-publisher publish
