Stripe has worked out how to let an agent near money: scoped OAuth, dedicated agent keys and a human click before refunds, all behind four compact tools.
Best for: Stripe users and integration developers who want an agent to look up payments, manage billing or plan an integration under tight controls.
Price: No charge for the server; normal Stripe fees apply to payments and products it touches. SQL queries through stripe_analytics need Stripe Sigma.

Any coding agent that touches Shopify's dated API versions should have this installed, ideally after creating the telemetry opt-out file.
Best for: Developers building Shopify apps, themes or extensions with a coding agent.
Price: Free; no Shopify account or authentication needed.

Useful for Plaid teams chasing broken connections and Link drop-off, and deliberately kept away from anything that reads customers' money or moves it.
Best for: Engineering teams integrating Plaid who want faster debugging and sandbox testing.
Price: Free to use for Plaid customers; Dashboard server needs approved production access.

Square's whole API behind three tools: clever for reading sales data, risky for anything that moves money while its beta bugs stay open.
Best for: Square sellers and developers who want an assistant to query sales, orders and catalog data.
Price: Free and open source (Apache-2.0); normal Square fees apply.

PayPal's own server covers the right merchant jobs, but the local package has been frozen for a year and an open issue from July reports the hosted sign-in failing.
Best for: PayPal merchants who want an assistant to manage invoices and look up transactions.
Price: Free to connect; normal PayPal fees apply.
