Square for payments
For payments, Square is our third pick of four, and it fits a specific merchant: one running retail and point-of-sale alongside online, not a developer wiring a pure online checkout. Its official server exposes the full Square API, payments, catalog, orders, customers, bookings, and inventory, so an agent can drive commerce flows across both channels.
Stripe and PayPal rank ahead for general payments because they lead developer-first card processing and broad consumer acceptance. Razorpay covers its region. Square earns the spot for retail and point-of-sale-driven businesses that want one server across the register and the website.
How Square fits
The server reaches the Square API through three tools. get_service_info discovers the methods on a service, get_type_info returns the parameters a chosen method requires, and make_api_request executes the call against the Square Connect API. For payments work an agent can create or read a payment, pull the order and customer behind it, and check inventory, composing each call from the discovery step rather than calling a fixed per-action tool.
The honest comparison: Stripe, the top pick, ships direct verbs for customers, payment links, and invoices and is the default for developer-led billing; PayPal is the widely accepted consumer option; Razorpay specializes regionally. Square's two-step discovery means an agent does more call composition than with a processor offering named payment tools, which is a fair tradeoff for the full-API reach. Choose Square when retail and point-of-sale are central and the agent should work the register and online catalog through one server; choose a sibling when pure online card processing is the whole job.

FAQ
- Who is the Square server the right payments pick for?
- Retail and point-of-sale-driven businesses that also sell online and run on Square. For developer-led online billing, Stripe (the top pick) fits better with direct tools for customers and invoices; PayPal covers broad consumer acceptance.
- Does Square have dedicated tools for creating a payment?
- It fronts the full Square API through three generic tools: get_service_info to discover methods, get_type_info for parameters, and make_api_request to execute. An agent composes a payment call from those rather than calling a single named create-payment tool.
