Methodology & citation

Figures are computed at build time from the 446 MCP servers in the HeyClaude registry, snapshot dated June 20, 2026. Transport and local/hosted classification are inferred from each server's declared config and install command (stdio for a local command, HTTP/SSE for a remote url or explicit transport). Trust and source provenance are assigned during maintainer review.
