# phatstacks > Shareable, forkable stacks for builders, set up by your coding agent in one command. - Reading stacks never needs an account; creating, saving and forking do. - The CLI (`npx phatstacks@0 use @handle/slug`) sets a project up from a stack; the MCP server at /mcp searches and reads them. - A stack's tools may carry add-ons (a CLI for the machine, a step in the project, an MCP server for the agent); only the catalog's commands run. - A stack may carry its author's own skills from public GitHub repos; they aren't from the catalog, and `use --install` asks before installing them. ## Docs - [Docs](https://phatstacks.dev/docs): what phatstacks is, signing in, the words it uses - [Full docs as Markdown](https://phatstacks.dev/llms-full.txt): the docs page in one file
