logomarks

Find, check, edit and build on free geometric logomarks from the command line or an AI agent. The Logomarks set is bundled (CC0, searched offline); the CLI checks marks against the set's house rules, edits and glitches them, and builds a brand kit, social pack, mockups and covers. It also runs as an MCP server. Pure JavaScript (resvg in WebAssembly), no native binaries, Node 20 or later.

Commands

npx logomarks find calm hexagon                       # search the set: slugs, styles, descriptions
npx logomarks get hex-gem --color '#ff5c3a' -o logo.svg
npx logomarks check mark.svg                          # every house rule; exit 1 on errors
npx logomarks similar mark.svg                        # the nearest live marks, with scores
npx logomarks edit quad-cove --ops '[{"op":"round","radius":18}]' -o mine.svg
npx logomarks glitch quad-cove --preset shear --seed 3 -o glitched.svg
npx logomarks kit hex-gem --name "Hexa Labs" --color '#ff5c3a' -o hexa/

Also specks, sheet, parts, combine, social, cover and mcp. Run logomarks --help for the list and logomarks <command> --help for a command's options. A mark is a live slug or name, or the path to your own .svg. Every edit comes back fitted to the grid and checked. Every command takes --json. Exit codes: 0 ok, 1 a check failed or the command failed, 2 usage.

AI agents

As a Claude Code plugin, with the two Logomarks skills (picking a mark, designing new ones) and this MCP server:

/plugin marketplace add logomarks/skills
/plugin install logomarks@logomarks

The skills alone, for any agent that reads skills (Claude Code, Cursor, Codex and more):

npx skills add logomarks/skills

The MCP server alone:

claude mcp add logomarks -- npx -y logomarks mcp
codex mcp add logomarks -- npx -y logomarks mcp
