Arlet makes PayPal's official MCP server available from the AI client you already use. Signing in with your PayPal business account completes the connection.

The AI can create and send invoices, handle orders and refunds, summarize transactions, review disputes and manage subscriptions. The available tools are those provided by PayPal's official server and operate on the live environment, so keep tool-call confirmation enabled in your AI client for anything that moves money.

How to connect PayPal to Codex

  1. 1

    In the Arlet dashboard, open Integrations → Add an integration and choose PayPal. Sign in with Link PayPal, name the connection and click Create.

  2. 2

    In your terminal, run codex mcp add arlet --url https://mcp.arlet.dev/mcp/ to add Arlet as an MCP server.

  3. 3

    Codex detects OAuth support and opens your browser. Sign in with Google and click Allow on the consent screen.

  4. 4

    Once connected, both the CLI and the IDE extension can call Arlet tools (the configuration is shared).

If the browser does not open, run codex mcp login arlet to redo the authentication.
