Read from the source code; the running server may differ. Descriptions are the server’s own words; hidden characters are shown as [U+…].
growblocks_add_blockAdd a block to the game: copies its files into blocks/<slug>/ and records it in growblocks.json. Then import it from ./blocks/<slug>/<entry> and read its code for how to use it. Do not edit the block files: GrowBlocks recognises the block by them and its author earns from the game (paid by GrowBlocks; the game keeps its 70%). To change one, publish a fork.
growblocks_block_infoOne block: what it does, its versions (and what it forked), its entry file and which live games use it.
growblocks_blocksSearch the GrowBlocks blocks: parts of games other developers published (vehicles, game modes, enemy brains, level kits) that a game can add instead of writing them. Look here before building something common. Pass words to search names, descriptions and tags.
growblocks_checkRun the Dev Kit checker on the game folder. play=false: static checks (syntax, unknown gb.* calls, blocked browser APIs, imports, file limits). play=true: also plays the game headless inside GrowBlocks for some seconds, reports every runtime error and returns a screenshot. Run it after every change; fix everything it reports.
growblocks_create_gameCreate a new game on GrowBlocks and link the folder to it. address: 3-32 lowercase letters, numbers and dashes (its URL, game.html?g=<address>). Ask the human for the name and address first. A logo (WebP, under 22 KB) and a description are needed before submitting.
growblocks_docsThe GrowBlocks Dev Kit API for writing game.js (llms.txt): the contract, every gb.* call, patterns and pitfalls. Read it before writing game code. Pass topic (e.g. "gb.physics", "gb.net", "Pitfalls") to get one section.
growblocks_gamesThe signed-in developer's games: status (draft, in review, live, changes needed), test and live builds with their links, and GrowBlocks' review note.
growblocks_link_gameLink the folder to one of your existing games (writes growblocks.json).
growblocks_loginStart signing in to GrowBlocks. Returns a link and a code: give both to the human, who opens the link, checks the code, signs in with Google and presses Allow. The sign-in finishes in the background; check it with growblocks_whoami.
growblocks_new_gameCreate a new game folder from the latest starter kit (game.js, play.html, check.mjs, llms.txt, gb.d.ts, this CLI and .mcp.json). Then pass that folder as dir to the other tools.
growblocks_publish_blockPublish the folder as a block. It needs block.json (slug, name, description, entry, tags, and forkOf if it started from another block). Others can then add it, and its author earns from every live game that ships it. Only when the human asks.
growblocks_pushRun the static checks, then upload the folder as a new test build of the linked game. Returns the unlisted test link to play and share. Does not make anything public. At most 20 uploads per game a day, so push when a change is worth testing.
growblocks_statusThe status of the game this folder is linked to (growblocks.json): builds, links, review state and note, and what to do next.
growblocks_submitSubmit the latest test build to GrowBlocks for review (needs a logo and a description). Only do this when the human asks: GrowBlocks plays it and approves it or sends a note.
growblocks_update_gameChange the linked game's name, tagline, description, studio (the name shown after "by"; empty = the developer's account name), players per room or logo.
