Official MCP4/5Good
Full official toolkit with a sandbox — the main gap versus Stripe is no first-party CLI for local workflows.

Square
Official MCP4/5Good
The retail-side counterpart to Stripe: official server, wide API surface, and 100KB of llms.txt documentation for agents to ground on.

Coinbase CDP
Official MCP4/5Good
The only entry here built for agents as the payer rather than the operator — per-tool docs are unusually thorough, and so are the consequences of a bad call.

Paddle
Official MCP4/5Good
Good fit for SaaS billing agents — merchant-of-record handling plus a first-party server, though it runs locally rather than hosted.

Adyen
Official MCP3.5/5Good
Vendor-maintained and genuinely write-capable on money movement. The gate is commercial: no merchant contract, no access.
