Plaid vs MX: two financial data networks, 20 points apart
Plaid scores 84.6 against MX's 64.9 and nearly doubles its agent readiness. MX ships four times as many APIs.
Plaid and MX both connect apps to bank accounts, and both are central to open banking in the US. On the rubric, Plaid is an exemplar at 84.6 and MX is strong at 64.9. Agent readiness splits even more: Plaid is agent-native at 52.1, MX agent-aware at 26.7.
Plaid’s lead comes from developer ergonomics (85.1 against 53.0), operational transparency (92.1 against 68.4) and access clarity (85.5 against 65.8). Plaid also publishes a first-party MCP server, OAuth scopes and source code. MX wins one facet, contract quality (72.8 against 69.2), and they tie on contract governance at 35.6 each.
MX publishes 31 APIs against Plaid’s 7, and it is the only one of the two shipping worked examples. MX has more surface and Plaid has more polish. Neither publishes an entry price the catalog can read: Plaid’s pricing basis reads negotiated, which is normal for regulated data networks.

What it costs to get in
Each provider's economics as the tool returns them. Grade A is quoted on the provider's own pricing page, B is arithmetic on quotes, C a stated prior. Entry cost is the cheapest published paid tier — a floor on getting in, not the price of the API alone. Grades: A quoted on the provider's page, B arithmetic on quotes, C a stated prior.
