An independent registry that probes MCP servers and x402 endpoints, preserving public evidence about availability, tools, payment terms, and observed behavior.

Why it surfaced

MCP Scores treats agent infrastructure as something to measure rather than merely list: its homepage reports 4,344 researched listings, including 2,130 that answered on their latest call and 1,959 that stayed silent. It also refuses to publish a grade below its evidence floor, returning “NR” when the record is insufficient.
