He is part of a group of British science fiction writers who specialise in hard science fiction and space opera. His contemporaries include Stephen Baxter, Iain M. Banks, Paul J. McAuley, Alastair Reynolds, Adam Roberts, Charles Stross, Richard Morgan, and Liz Williams. His science fiction novels often explore socialist, communist, and anarchist political ideas, especially Trotskyism and anarcho-capitalism. Technical themes encompass singularities, divergent human cultural evolution, and post-human cyborg-resurrection. MacLeod's general outlook can be best described as techno-utopian socialist, though unlike a majority of techno-utopians, he has expressed great scepticism over the possibility and especially over the desirability of strong AI. He is known for his constant in-joking and punning on the intersection between socialist ideologies and computer programming, as well as other fields. For example, his chapter titles such as "Trusted Third Parties" or "Revolutionary Platform" usually have double meanings. A future programmers union is called "Information Workers of the World Wide Web", or the Webblies, a reference to the Industrial Workers of the World, who are nicknamed the Wobblies. The Webblies idea formed a central part of the novelFor the Win by Cory Doctorow and MacLeod is acknowledged as coining the term. Doctorow and Charles Stross also used one of MacLeod's references to the singularity as "the rapture for nerds" as the title for their collaborative novel Rapture of the Nerds. There are also many references to, or puns on, zoology and palaeontology. For example, in The Stone Canal the title of the book, and many places described in it, are named after anatomical features of marine invertebrates such as starfish.

The Restoration Game. According to the author, "In The Restoration Game I revisited the fall of the Soviet Union, with a narrator who is at first a piece in a game played by others, and works her way up to becoming to some extent a player, but – as we see when we pull back at the end – is still part of a larger game."
Intrusion : "an Orwellian surveillance society installs sensors on pregnant women to prevent smoking or drinking; and these women also have to take a eugenic 'fix' to eliminate genetic anomalies.
Descent : "My genre model for Descent was bloke-lit – that's basically first-person, self-serving, rueful confessional by a youngish man looking back on youthful stupidities...... Descent is about flying saucers, hidden races, and Antonio Gramsci's concept of passive revolution, all set in a tale of Scottish middle class family life in and after the Great Depression of the 21st Century. Almost mainstream fiction, really."
