Web Agent-Readiness Leaderboard
Agent-readiness scores for websites and their MCP servers, scored against the same eight principles as the CLI leaderboard. See the methodology for how the web audit probes MCP shape, discovery surfaces, and machine-readable content.

How web scoring works
Each website is probed for its MCP server shape, MCP and agent discovery surfaces, machine-readable content (llms.txt, OpenAPI, JSON Schemas), root-HTML affordances, and crawl policy. Checks that do not apply to a site (no MCP server, no API surface, a different declared site type) are excluded rather than counted against it. Relative measures how agent-ready a site is for the checks that apply to it, so a site perfect for its type approaches 100%; Global measures absolute agent capability against a maximally agent-ready site, so exposing and nailing more surfaces ranks higher. The board sorts by Relative by default; each result page headlines Relative.
The curated set is hand-picked; the all view also lists sites audited on demand, which stay on the board
until their cached result ages out. To score any public site, use the web audit or the
audit_website MCP tool.
