MCP tool
register
register is a tool name used by 3 different MCP servers. They are not necessarily the same tool — here is what each one does.
3 MCP servers expose a register tool: AWS Cloud Service Updates & Announcements — buy per-query (awswhatsnew), GitHub Platform Changelog — buy per-query in-session (githubchangelog) and Trending Repository Tracker — new GitHub repo discovery ($0.01/query). Their input schemas differ, so compare them below before picking one.
