What this publisher publishes
Names under io.github.copyleftdev/ can only be published by someone who signs in to the MCP Registry as the GitHub user copyleftdev, or as a member of the GitHub organisation of that name. The name shows which GitHub account published the entry; it does not show that the account belongs to the company whose product a server works with.
