As of July 5, 2026, the official MCP registry lists 14,853 servers, and Smithery's directory lists 6,718 — two partially-overlapping measures of how many machine-callable services agents can reach. Counts come from full registry walks, not samples, and refresh with the web-sources pipeline.
Why a server count belongs in an agent-economy dataset
MCP servers are the supply side of the agent economy: each one is a capability an agent can call — and increasingly, pay for. Counting them tracks how much machine-callable surface area exists, the same way counting storefronts tracks a retail economy. agent economy counts the official MCP registry by walking its full API (no sampling), with Smithery's directory as a second, partially-overlapping measure.
Registry counts are supply, not demand: a listed server may be popular, abandoned, or duplicated across directories, and the two directories overlap in unknown proportion — which is why they are reported side by side rather than summed. Directionally, the growth of these registries is one of the cleanest adoption signals the agent ecosystem has.
Also asked
Can these two counts be added together?
No — the directories overlap in unknown proportion, so summing them double-counts. Report them side by side, or pick the official registry as the conservative single figure.
