Summary
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.
Keep your Mac awake while Claude Code and 40+ AI agents run. Sleeps when they're idle.

Linggen Releases
Public download host for branded Linggen apps on macOS. All published builds are codesigned and notarized.
Linggen is a local AI app engine — the core runtime (engine source) hosts skills as full-featured native apps. Each branded app bundles the engine + a primary skill into one
.app. Apps share a local daemon (http://127.0.0.1:9898) and the~/.linggen/data directory.
Apps
Sys Doctor — coming soon
On-device macOS health analyst. Inspects disk, memory, processes, network, security, and battery; explains findings in plain English; suggests cleanup with copy-paste commands.
- Tag scheme (when released):
sys-doctor-v<version> - Source: linggen/linggen-app (private)
More branded apps planned (House Keeper, Majiang, Suanming, …) — see the roadmap.
Install (once a DMG is published)
- Download the
.dmgfor the app you want from Releases. - Open it; drag the app into
/Applications. - First launch: the app spawns the bundled
lingengine on127.0.0.1:9898(or reuses one already running). The daemon self-terminates after 5 min idle.
All Linggen apps share one local daemon and one ~/.linggen/ directory (sessions, memory, skills, credentials).
Tag schemes
| Tag pattern | Where | What |
|---|---|---|
<app>-v<version> | this repo | branded native app .dmg (e.g. sys-doctor-v0.1.0) |
v<version> | linggen/linggen | the ling CLI / engine binary on its own |
The engine binary is not published here. Branded apps bundle their own copy of ling; this repo only hosts the user-facing app DMGs.
