PassNinja MCP server

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)

brew tap flomio/passninja
brew install passninja

Windows (PowerShell)

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

From cmd.exe:

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:

$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:

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

Claude Desktop (one-click .mcpb install)

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

from the latest release.

1. Download passninja.mcpb

31 tools the server exposes (pass templates, issued passes, webhooks, scan-event applications and readers).

1. Double-click the file. Claude Desktop opens an install dialog showing the

get them at https://www.passninja.com/settings → API key.

1. The dialog prompts for your API key and account ID —

1. 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 jane@example.com.

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

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:

export PASSNINJA_API_KEY=...        PASSNINJA_ACCOUNT_ID=aid_0x002
passninja --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 PASSNINJAAPIKEY / PASSNINJAACCOUNTID 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):

whoami
pass_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.
