connect is a tool name used by 4 different MCP servers. They are not necessarily the same tool — here is what each one does.
4 MCP servers expose a connect tool: read-only-local-mysql-mcp-server, read-only-local-postgres-mcp-server, memory-nexus-mcp and nexus-memory-mcp. Their input schemas differ, so compare them below before picking one.
