Connects Claude to Linggen's local daemon at 127.0.0.1:9898 for privacy-first code search using RAG. Everything runs on your machine with data stored in ~/.linggen/, so nothing leaves your system. Linggen itself is a local AI app engine that bundles skills into native macOS apps, all sharing one daemon and storage directory. The MCP server lets you query your indexed code directly from Claude without sending it to external services. Reach for this when you want semantic code search across your projects but need to keep source code strictly local, or when you're already running Linggen apps like Sys Doctor and want Claude to tap into the same indexing layer.
Public download host for the Linggen macOS app.
Linggen is a local AI app engine — the core runtime (engine source) hosts skills as full-featured native apps. The app bundles the engine and its skills into one
.app, served from a local daemon (http://127.0.0.1:9527) with all state under~/.linggen/.
curl -fsSL https://linggen.dev/install-app.sh | bash
Curl rather than a browser download on purpose: macOS attaches a quarantine
attribute to anything a browser fetches, and these builds are ad-hoc signed
rather than notarized, so a downloaded copy would be blocked on first launch.
The installer fetches the tarball, checks its sha256, and puts Linggen.app
in /Applications.
On first launch the app starts the bundled ling engine on 127.0.0.1:9527,
or reuses a healthy daemon already listening there. The daemon shuts itself
down after 5 minutes idle. Updates arrive through the app's own updater.
One app, one launcher, several skills as tabs:
ling-mem daemonMac Shifu (formerly Sys Doctor) and CFO were once separate downloads. They are
skills inside the one app now, and linggen.dev/install-sys-doctor.sh and
install-cfo.sh redirect here.
| Tag pattern | Where | What |
|---|---|---|
linggen-v<version> | this repo | the macOS app tarball + .sha256 |
<version>, no prefix | linggen/linggen | the ling engine binary, macOS and Linux |
v<version> | linggen/linggen-memory | the ling-mem memory daemon |
Only the app is hosted here. It bundles its own copy of the engine, so the app version and the engine version move independently.
Builds are macOS arm64, ad-hoc signed, not notarized. The app source lives in
linggen/linggen-app (private); the engine, the skills, and the memory daemon
are public.
