PassFast

PassFast MCP

Remote HTTPS Model Context Protocol server for [PassFast](https://passfa.st) — Apple Wallet + Google Wallet passes from any MCP client (Cursor, Claude, ChatGPT, Codex, Grok).

This repository is the public metadata + install kit for marketplace listings (official MCP Registry, Grok Build plugins, open directories). The server itself is hosted at passfa.st — there is no local stdio binary here.

Auth

Authorization: Bearer sk_live_YOUR_SECRET_KEY

X-App-Id: YOUR_APP_ID # optional for single-app orgs

• Secret keys only (sk_live_). Publishable pk_live_ keys are rejected.
• No OAuth, no PassFast agent account — the MCP client *is* the agent.
• Member/invite tools need a user JWT and are out of scope for key-auth MCP v1.

Install

Cursor

Copy cursor/mcp.json into ~/.cursor/mcp.json or project .cursor/mcp.json, then replace the placeholders.

Claude (HTTP)

{

"mcpServers": { "passfast": { "type": "http", "url": "https://passfa.st/mcp", "headers": { "Authorization": "Bearer sk_live_YOUR_SECRET_KEY", "X-App-Id": "YOUR_APP_ID" } } } }

Stdio-only clients: npx mcp-remote https://passfa.st/mcp with the same headers via your client’s env/header support.

Generic / registry

See server.json for the official MCP Registry remote descriptor (Streamable HTTP + auth headers).

What agents can do

• List / publish templates; generate dual-wallet passes; download .pkpass
• Update / void passes; share links + QR
• Upload images & signing credentials; manage apps / org / API keys
• Same billing as the HTTP API (see https://passfa.st/#pricing)
