Tool changes across remote MCP servers in the Official MCP Registry, newest firs
Tool changes across remote MCP servers in the Official MCP Registry, newest first: tools added, removed or redefined (description, input schema or annotations), from our daily fingerprints. A tool that changes after you approved it is how 'rug pull' attacks work, so check before trusting a server again. Last 1 to 30 days, or one server with name= or url=. Servers whose tools change by design are marked. Signed.
