Which domain is really the official one?

An open registry of domain ↔ organization ownership, for AI agents and people. Not a safety judgement — only ownership, and only when the evidence is reproducible.
域名到底属于谁——只判归属，不判安全；每一条都能复现。

How to use it from an AI agent

claude mcp add realurls -- npx -y @realurls/mcp
# or any MCP host:  { "command": "npx", "args": ["-y", "@realurls/mcp"] }
# plain HTTP:       curl "https://api.realurls.org/v1/resolve?domain=claude-desktop.io"

The MCP server ships instructions telling the agent to call it before handing out any download or login link — in our tests that single line is what turns "answers from memory" into "verifies first".

Verified organizations

What "verified" means

At least one anchor (something only the real owner can produce: a GitHub-verified org, a DNS self-attestation, a restricted government TLD, a long-lived repository whose homepage points here…) and at least two independent corroborations. Anything less is reported as insufficient evidence. We would rather say "don't know" than be wrong. Full rules: POLICY.md.
