Add MCP servers and skills to a local registry, scope them per project, and keep credentials in your OS keychain — never in files.\n\n### Highlights\n\n- **One registry, every project** — add MCPs and skills once from npm, PyPI, GitHub, or local sources. No more copy-pasting `.mcp.json`.\n- **Secrets in your keychain** — API keys live in macOS Keychain, Linux Secret Service, or an age-encrypted vault. Launcher scripts fetch them at runtime.\n- **Scoped per project** — each project declares its tools in `crux.json`. Agents see only what's declared — fewer tools means better outputs.\n- **Sandboxed execution** — `crux run` creates isolated environments with pre-flight validation. Misconfigurations are caught before your agent starts.\n- **Health monitoring** — `crux status` probes every MCP via JSON-RPC. `crux doctor` validates your environment and auto-fixes what it can.\n- **Discover \u0026 search** — search the official MCP registry from your terminal and add servers with one command.\n\n## Install\n\n**As a Claude Code plugin** (recommended):\n\n```bash\nclaude plugin marketplace add crux-cli/claude-marketplace\nclaude plugin install crux\n```\n\n**Or via curl:**\n\n```bash\ncurl -LsSf https://raw.githubusercontent.com/crux-cli/crux/main/install.sh | sh\n```\n\nOr if you already have [uv](https://docs.astral.sh/uv/): `uv tool install crux-cli \u0026\u0026 crux setup`\n\n## Get started in three steps\n\n**1. Build your registry** — add MCP servers and skills from any source:\n\n```bash\ncrux add mcp filesystem --npx @modelcontextprotocol/server-filesystem\ncrux add mcp wikijs --github jaalbin24/wikijs-mcp-server\ncrux add skill autoresearch --github user/autoresearch-skill\n```\n\n**2. Store credentials securely** — API keys go in your OS keychain:\n\n```bash\ncrux secret set wikijs WIKIJS_API_KEY\ncrux secret set github GITHUB_TOKEN\n```\n\n**3. Use in a project or a one-off sandbox:**\n\n*Project mode* — declare what each project needs in a `crux.json` manifest:\n\n```bash\ncrux init homelab-assistant \u0026\u0026 cd homelab-assistant\ncrux install wikijs filesystem autoresearch\ncrux status\n```\n\n*Sandbox mode* — run an agent with a specific set of tools, without a full project:\n\n```bash\ncrux run \"Update the wiki with latest research\" \\\n  --mcps wikijs --skills autoresearch\n```\n\n## Replaces manual management of\n\n| What | Without Crux | With Crux |\n|------|-------------|-----------|\n| **MCP config** | Hand-edited `.mcp.json` per project | `crux.json` manifest + `crux sync` |\n| **Credentials** | Plaintext `.env` files committed to git | OS keychain, fetched at runtime |\n| **Tool scoping** | Every agent sees every tool | Each project declares its own subset |\n| **Skills** | Files manually copied between machines | Registry with `crux add skill` |\n\n## Commands\n\n```\nSetup:\n  crux setup                  Initialize ~/.crux and environment\n  crux doctor                 Diagnose and auto-fix environment issues\n\nRegistry:\n  crux add mcp \u003cname\u003e         Register an MCP (npm, PyPI, GitHub, local)\n  crux add skill \u003cname\u003e       Register a skill\n  crux remove \u003cname\u003e          Unregister an MCP or skill\n  crux list                   List everything in the registry\n  crux search \u003cquery\u003e         Search the official MCP Registry\n  crux upgrade [\u003cname\u003e]       Update cloned sources to latest\n\nProject:\n  crux init [\u003cname\u003e]          Create a project with crux.json\n  crux install \u003cname...\u003e      Add MCPs/skills to project and sync\n  crux uninstall \u003cname...\u003e    Remove MCPs/skills from project and sync\n  crux sync [--all]           Generate .mcp.json from crux.json\n  crux status [--all]         Show MCP server health\n\nSecrets:\n  crux secret set \u003cmcp\u003e \u003ckey\u003e Store a secret in OS keystore\n  crux secret get \u003cmcp\u003e \u003ckey\u003e Retrieve a secret\n  crux secret list [\u003cmcp\u003e]    List stored secrets (values masked)\n\nSandbox:\n  crux run \u003ctask\u003e             Execute agent with scoped MCP access\n  crux run --file \u003cmanifest\u003e  Execute from a reusable run manifest\n  crux run list               List recent runs\n  crux run clean              Remove completed sandboxes\n```\n\n## Security\n\nCrux takes an opinionated stance: **there is no insecure-but-easier path.**\n\n- Secrets never appear in any file on disk — only in your OS keystore\n- Launcher scripts contain keystore lookup commands, not credential values\n- Generated `.mcp.json` never contains secrets\n- Each sandbox gets only the MCPs explicitly declared for that run\n- Path traversal protections on all file operations\n\n## Documentation\n\nFull docs, guides, and API reference at [crux-cli.github.io/crux](https://crux-cli.github.io/crux).\n\n## Development\n\n```bash\ngit clone https://github.com/crux-cli/crux\ncd crux\nuv sync --extra dev\nuv run pytest tests/ -v\n```\n\n## License\n\n[MIT](LICENSE)\n","project_url":"https://awesome.ecosyste.ms/api/v1/projects/github.com%2Fcrux-cli%2Fcrux","html_url":"https://awesome.ecosyste.ms/projects/github.com%2Fcrux-cli%2Fcrux","lists_url":"https://awesome.ecosyste.ms/api/v1/projects/github.com%2Fcrux-cli%2Fcrux/lists"}
