Spec Driven Development
MCP Server that facilitates spec-driven development workflows, not just Vibe Coding.
Descripción del creador (original en inglés)
Keep credentials out of AI coding agents with local approvals, scoped injection, and audit trails.
Estos tres nunca se combinan en una sola puntuación: las opiniones, las mediciones y la popularidad son cosas distintas.

s-gw
Local credential control for coding agents.
Approve bounded actions locally. Keep raw credentials out of model context and tool output.
Demo · Downloads · Quick start · Documentation · Security · Contributing
Stop handing raw credentials to coding agents. s-gw gives agents typed handles, asks you to approve bounded local actions, resolves the credential inside a constrained process on your machine, and returns sanitized output instead of secret values.
[!IMPORTANT]
s-gw is an early preview. Storage formats and interfaces may change, Windows and Linux desktop support is still experimental, and the project has not completed an independent security audit. Do not treat it as a replacement for endpoint security or a hardened enterprise secrets platform yet.
The TypeScript broker, clients, and documentation in this repository are Apache-2.0 licensed. Distributed packages also contain a proprietary compiled Rust execution core whose source is maintained separately.
s-gw:credential:prod-readonlyIf s-gw helps your agent workflow, star the project. It makes the preview easier for other developers to find.
The local console shows the approval queue, credential inventory, policy state, usage flow, and activity history without exposing secret values.
Public demo: s-gw.com.
| Govern | Approve | Execute | Audit |
|---|---|---|---|
| Turn secrets into typed local handles that agents can reference safely. | Review the requesting agent, handle, command, environment binding, working directory, and target before access is granted. | Inject the credential only into the approved child process on the same machine. | Record request, approval, execution, policy, and destination evidence without storing returned raw secrets. |

The agent never needs the unlock passphrase or raw credential. Approval is scoped to the requested operation rather than granting general access to the store.
| Surface | Purpose |
|---|---|
s-gw CLI | Setup, credential enrollment, approvals, policies, agent snippets, guard mode, and diagnostics. |
s-gw-mcp / s-gw mcp | Stdio MCP server for agent-facing handle discovery and request creation. |
| Native macOS app | Approval queue, credential inventory, policy rules, usage flow, activity, and audit review. |
| Windows and Linux desktop apps | Installed preview apps with a native window, tray controls, and a bundled local runtime. |
| Menu-bar helper | Fast visibility into pending approvals and local daemon status. |
| Local web console | Browser backup bound to 127.0.0.1; it remains available when a desktop app cannot run. |
| Guard mode | Launch agents with credential-looking environment values replaced by s-gw handles. |
The public npm package is the recommended installation path on macOS, Windows 10/11, and Linux. Install Node.js 20 or newer, then run:
npm install -g @s-gw/s-gw
s-gw setup s-gw status
On Windows, run the same commands in PowerShell. Windows support is preview software: the npm package uses the TypeScript execution path and includes the PowerShell client, tray helper, and local web console.
On Linux, install secret-tool first (sudo apt install libsecret-tools on Ubuntu/Debian). An unlocked desktop Secret Service is the normal persistent unlock provider; s-gw setup also installs and starts an owner-level systemd --user console service for the graphical session. A headless host without Secret Service can use an explicitly supplied SGW_MASTER_PASSPHRASE with s-gw setup --no-service --no-open-app, but s-gw never copies that value into a unit file or background-service environment.
Windows x64 and Linux x64 also have installable desktop-app builds. The Rust app draws its management interface directly in a native window; it does not embed a browser, WebView, or localhost page. It packages its own pinned Node runtime and s-gw CLI, so the installed app does not require host Node.js or npm. When the native executable is installed, s-gw app open uses it. Use s-gw app open --browser to start and open the separate loopback browser backup explicitly.
These Windows NSIS and Linux Debian packages are currently unsigned CI previews, not supported public release downloads. Windows does not require WebView2. Linux requires a graphical session and an unlocked Secret Service keyring; the Debian package declares its GTK 3, AppIndicator, libxdo, and libsecret-tools runtime dependencies. See deployment and packaging for build and install details.
For an Apple Silicon Mac desktop bundle, GitHub Releases also provides a self-contained s-gw.dmg. Drag s-gw.app to Applications, then open it and complete setup. The app includes its own Node runtime, CLI, MCP server, native helpers, and menu-bar helper; it does not require Node.js or npm on the host. Setup is intentionally blocked until the app is in /Applications or ~/Applications.
An unsigned DMG requires a Gatekeeper override. Use the npm installation above instead if you do not want to use that override.
The public source builds the TypeScript compatibility path and the native-rendered Windows/Linux Rust desktop app. Building the native macOS surfaces also requires a Swift toolchain. Windows and Linux desktop builds require Rust and their ordinary native graphics and tray development libraries. Maintainer release builds additionally require access to the private Rust core checkout.
The Apple Silicon Mac DMG is a self-contained desktop alternative. Published macOS DMGs are either Developer ID signed and notarized or explicitly documented as unsigned; unsigned builds require a Gatekeeper override but retain the standard release tag and update path. Local npm run build:installers output is ad-hoc signed for local verification. The npm package is the primary install and includes the native app, menu helper, Keychain helper, metadata-only Keychain inspector, and Rust core for Apple Silicon Macs. Linux and Windows use the TypeScript execution path when a matching native core is not packaged. Intel Macs must build the native Keychain and desktop surfaces from source for now; packaged arm64-only helpers are rejected before launch.
git clone https://github.com/sgateway/s-gw.git
cd s-gw npm ci npm run build npm link s-gw setup s-gw status
s-gw setup generates local unlock material, stores it in the operating system credential store, initializes the encrypted ledger, starts the local UI surfaces available on the current platform, and safely connects detected supported agents. The self-contained macOS app and the Windows/Linux desktop previews run their bundled runtimes in place; npm installs copy the thin macOS app into /Applications, falling back to ~/Applications when needed. Setup backs up existing agent config, preserves unrelated settings, installs the packaged s-gw skill where supported, and reports per-agent conflicts. Use --no-agents to skip agent registration.
Add a credential from your terminal without placing the value in chat or a process argument:
printf '%s' "$MY_API_TOKEN" | s-gw secret add-keychain \
--name demo-token \ --type api-token \ --value-stdin \ --inject-env API_TOKEN \ --allow-command "$(command -v printenv)"
Then inspect the non-secret handle metadata:
s-gw secret list
The end-to-end trust loop walks through a disposable request, local approval, execution, and output sanitization without touching a real credential.
Use a disposable local token to see the full flow:
printf '%s' 'demo-secret-value' | s-gw secret add-keychain \
--name demo-printenv-token \ --type api-token \ --value-stdin \ --inject-env DEMO_TOKEN \ --allow-command "$(command -v printenv)"
s-gw request env-command \ --command "$(command -v printenv)" \ --inject-env DEMO_TOKEN
s-gw approve s-gw execute
The execution output should show a handle token instead of demo-secret-value.
List the known agent profiles and render the configuration for one client:
s-gw agent list
s-gw agent mcp-snippet codex s-gw agent mcp-snippet claude-code s-gw agent mcp-snippet opencode
Review or manage detected connections:
s-gw agent status
s-gw agent install codex --dry-run s-gw agent install codex s-gw agent uninstall codex
Manual profiles and config formats without a safe merge path continue to use the generated snippet. npm installation itself never edits agent configuration.
s-gw setup can safely manage detected Claude Code, Codex, Cursor, Gemini CLI, GitHub Copilot CLI, OpenCode, and default-profile VS Code installations on macOS, Windows, and Linux. On Windows, it launches the packaged MCP server through node.exe, not an n
