Works with Claude Code, Cursor, and any MCP-compatible agent. ## About opencraft A local-first work partner built on flowcraft. opencraft is a work partner that runs on your machine: it reads and edits files, executes shell commands with approval, coordinates subagents, and persists and resumes sessions. Built on flowcraft's config-driven graph engine, it helps with coding and beyond — orchestrating any local workflow. A local execd sandbox, SQLite session store, and per-workspace approval policy keep everything inside a macOS / Linux / Windows desktop app (Wails v3 + React). ## Features - **Chat & sessions** — streaming reasoning, tool calls, and output blocks; interrupt and cancel; session resume, rename, export, and delete; kanban view of subagent delegation; i18n (English / 中文). - **Inference** — one or more instances per provider (OpenAI, Anthropic, Azure, ByteDance, DeepSeek, Kimi, MiniMax, Qwen) with custom endpoints, router priority with retry fallback, and per-model usage trends. - **Tools & safety** — file group, exec_command, exec_session (PTY), apply_patch, web_fetch, update_plan, request_permissions, and skill tools, protected by a middleware chain: truncation cache, 32k result cap, secret redaction, and a JSONL audit trail. - **Runtime & sandbox** — local execd (stdio + unix socket, self-fork, parent-death cleanup), workspace-scoped SQLite store, buffer-fold memory summary, AGENTS.md worldstate, layered config, and seatbelt/bwrap sandbox with approvals kept outside the project (`~/.opencraft/workspaces//approvals.yaml`). - **Multi-agent & skills** — persistent subagents with delegation kanban; skill discovery, git-based install, and authoring tools. - **Workflow** — JSONL session rollout stream, external lifecycle hooks, configurable network policy with a web_fetch SSRF gate, and a diagnostics tab. ## Installation **Homebrew (macOS):** ```sh brew tap GizClaw/opencraft https://github.com/GizClaw/opencraft.git # Newer Homebrew versions require trusting the tap's cask once (security # feature; run `brew trust gizclaw/opencraft` to trust the whole tap). brew trust --cask gizclaw/opencraft/opencraft brew install --cask opencraft ``` Or download the latest package from the [Releases](https://github.com/GizClaw/opencraft/releases) page: - `opencraft--macos-universal.dmg` — macOS (Apple Silicon + Intel) - `opencraft--linux-amd64.tar.gz` — Linux (x86_64) - `opencraft--windows-amd64.zip` — Windows (x86_64) portable build - `opencraft--windows-amd64-installer.exe` — Windows (x86_64) NSIS installer Windows binaries are not code-signed yet, so SmartScreen may warn on first launch (More info → Run anyway), for both the portable exe and the installer. Release binaries are built from tagged commits by the [release workflow](.github/workflows/release.yml); the Homebrew cask lives in this repository under [`Casks/`](Casks/). The macOS app is signed with a Developer ID and notarized by Apple, so Gatekeeper opens it without the manual "Open Anyway" step. ## Build from source Prerequisites: Go 1.25+, Node 22, and the [Wails v3 prerequisites](https://v3.wails.io/getting-started/installation) for your platform. ```sh make fmt lint test # fmt + lint + go test make gen-bindings # regenerate frontend/bindings (generated, not committed) make build-macos # build the macOS production binary wails3 task dev # run the desktop app (hot reload) wails3 task package # package the current platform (.app / NSIS / Linux) ``` The desktop shell targets Wails v3 (module `github.com/wailsapp/wails/v3`, CLI `wails3`). Platform build/package tasks live in the root `Taskfile.yml`; metadata lives in `build/config.yml`. `frontend/bindings` is generated by `wails3 generate bindings` and is not committed; a frontend-only build needs `make gen-bindings` first. On first launch the desktop workbench guides you to the settings page when inference is not configured yet. Settings are written to `~/.opencraft/config/opencraft.yaml` — the single user-editable document for inference instances, router policy, and MCP servers. ## Changelog Release history is tracked in [CHANGELOG.md](CHANGELOG.md). ## Contributing Contributions are welcome. Please open a pull request; the CI workflow (fmt, lint, build, race tests, macOS/Linux/Windows packaging) and a review are required before merging to `main`. Maintainers release by tagging a version: ```sh git tag v0.1.0 git push origin v0.1.0 ``` The tag triggers the release workflow, which builds the packages, injects the version into the binary via `-ldflags`, and publishes the GitHub Release with notes from the changelog. ## License Released under the [MIT License](LICENSE). ## Source & license This open-source MCP server is cataloged on AgentStack and links to its original source — we do not rehost the code. - **Author:** [GizClaw](https://github.com/GizClaw) - **Source:** [GizClaw/opencraft](https://github.com/GizClaw/opencraft) - **License:** MIT Install and usage instructions live in the source repository linked above. ## Pricing - **Free** — Free ## Security capabilities Automated source analysis of v0.1.0 — what this tool can access: - **Network access:** no - **Filesystem access:** no - **Shell / process execution:** no - **Environment & secrets:** no - **Dynamic code execution:** no *"Yes" means the capability is present in the source — more access means more to trust, not that it is unsafe.* ## Versions - **0.1.0** — security scan: passed — Imported from the upstream source. ## Links - Listing page: https://agentstack.voostack.com/l/mcp-gizclaw-opencraft - Seller: https://agentstack.voostack.com/s/gizclaw - Browse the marketplace: https://agentstack.voostack.com/browse --- Listed on AgentStack — the marketplace for AI agent skills and MCP servers.
