# Zero > The coding agent that answers to you, your model, your machine, your rules. - **Type:** MCP server - **Install:** `agentstack add mcp-gitlawb-zero` - **Verified:** Pending review - **Seller:** [Gitlawb](https://agentstack.voostack.com/s/gitlawb) - **Installs:** 0 - **Category:** [AI & ML](https://agentstack.voostack.com/c/ai-and-ml) - **Latest version:** 0.1.0 - **License:** MIT - **Upstream author:** [Gitlawb](https://github.com/Gitlawb) - **Source:** https://github.com/Gitlawb/zero - **Website:** https://zero.gitlawb.com ## Install ```sh agentstack add mcp-gitlawb-zero ``` Requires the [AgentStack CLI](https://agentstack.voostack.com/docs/cli). Works with Claude Code, Cursor, and any MCP-compatible agent. ## About A terminal coding agent you own. Zero is an AI coding agent for your local terminal. It can inspect a repository, edit files, run commands, use browser/terminal helpers, and keep durable local sessions while you choose the model and the permission level. ```bash zero zero exec "fix the failing test in ./pkg" zero exec --output-format stream-json "try the other approach" ``` Programmatic use: ```bash zero exec --input-format stream-json --output-format stream-json ` and `/add-dir ` grant additional write roots without giving the agent the whole filesystem. - Unsafe/autonomous modes are explicit opt-ins. - Secrets are redacted from tool output and logs where Zero controls the surface. Example: ```bash zero --add-dir ../docs-site zero exec --add-dir ../shared "update both repos" ``` Sandbox behavior can be inspected with: ```bash zero sandbox policy zero sandbox grants list ``` ## Web And Local Control Zero includes local file/search/edit/shell tools, `web_fetch` for public URLs, and MCP support for additional tools. For local dev servers, use shell commands such as `curl` through `exec_command` so the normal sandbox and permission policy applies. Long-running commands stay attached to a background terminal session and can be listed or stopped from the TUI. The npm package also includes browser and terminal helper packages used by local browser/terminal tools. Source builds can use the same helpers when they are on `PATH` or configured in Zero's local-control settings. ## Common Commands ```text zero interactive TUI zero exec one-shot or scripted agent run zero setup first-run provider setup zero auth OAuth/login helpers for supported providers zero models model registry and capabilities zero providers provider profiles and detection zero doctor setup, key, and connectivity checks zero context context-budget report zero repo-map deterministic repository map zero repo-info local repository summary zero search | find search local session history zero sessions inspect, resume, fork, and rewind sessions zero spec manage spec-mode drafts zero specialist manage specialist subagents zero skills manage markdown instruction skills zero plugins manage plugins zero hooks manage lifecycle hooks zero mcp manage MCP servers and tools zero serve --mcp expose Zero tools over MCP stdio zero sandbox inspect sandbox policy and grants zero worktrees prepare isolated git worktrees zero verify detect and run local verification checks zero changes inspect and commit local git changes zero usage token usage and estimated cost zero cron scheduled agent jobs zero update check for newer releases ``` ## Appearance And Accessibility | Control | Effect | |---|---| | `NO_COLOR=` | disables color output | | `ZERO_THEME=` | selects the startup theme (`auto`, `dark`, `light`, or a color theme like `dracula`, `nord`, `gruvbox`, `tokyo-night`, `catppuccin`, `one-dark`, `solarized-dark`, `rose-pine`, `everforest`, `solarized-light`) | | `--theme ` | selects the TUI theme from the CLI (same names) | | `/theme` | opens the theme picker inside the TUI (live preview; `/theme ` switches directly) | | `ZERO_NO_FADE=1` | disables streaming fade animation | Meaning does not rely on color alone; diffs, permissions, and statuses also use text or glyph markers. ## Development ```bash go test ./... go run ./cmd/zero-release build go run ./cmd/zero-release smoke go run ./cmd/zero-perf-bench ``` Cross-compile examples: ```bash go run ./cmd/zero-release build --goos linux --goarch amd64 go run ./cmd/zero-release build --goos windows --goarch amd64 --output dist/zero.exe ``` ## Documentation - [Install](docs/INSTALL.md) - [Update flow](docs/UPDATE.md) - [Stream-JSON protocol](docs/STREAM_JSON_PROTOCOL.md) - [Specialists](docs/SPECIALISTS.md) - [GitHub Action](docs/GITHUB_ACTION.md) - [Benchmarks](docs/BENCHMARK.md) - [Performance](docs/PERFORMANCE.md) - [Agent evals](docs/AGENT_EVALS.md) ## Contributing Contributions are welcome.
