Add this to your client's MCP configuration (Claude Desktop: claude_desktop_config.json; Cursor: .cursor/mcp.json; VS Code and others use the same "mcpServers" shape).

PassFast MCP

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

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)

Starter prompts

See skills/passfast/SKILL.md.

Marketplace submissions
