About PayPal, guarded
PayPal, guarded is an MCP server published by the GitHub account Fizzl13. PayPal's Agent Toolkit with limits on refunds and the owner's Approve/Deny above them.
It runs on your own machine: your AI client starts it from the npm package fizzl-paypal-guard-mcp at version 0.2.1.
It asks for 3 secrets: PAYPAL_CLIENT_SECRET, FIZZL_AGENT_KEY and TELEGRAM_BOT_TOKEN. Give it a key with the least access that still works.
It also needs PAYPAL_CLIENT_ID set before it starts.
Version 0.2.1 was published on 22 October 2026, and the source code is public, so you can read it before installing.
