Known Good

ClaudeCommunityby Known Good

Known Good is an index of websites whose agent-facing capabilities were verified by a probe, not declared. Ask it for sites where an agent can do a task and it returns listed sites with what each one answers: markdown on request, an API catalogue, an MCP server that returns its tool list, WebMCP tools in the page. Every result carries the date it was tested. Three tools: find sites by capability, read a site's full report, check a page for WebMCP. Public data, no key needed.
