## Linggen

**Linggen** is a **local-first RAG + MCP memory layer** for AI coding assistants.

It runs entirely on your machine, is **free for individuals and teams**, and is built for:

- **Working across many projects** with one shared memory layer

- **Navigating huge codebases and documentation sets**

- **Connecting multiple IDEs/agents via MCP** (Cursor, Zed, Windsurf, etc.)

Nothing leaves your machine by default: embeddings, indexes, and search all run locally.

## What You Can Do

- **Index your world**: local folders, codebases, docs, and notes

- **Semantic search + AI chat** over everything you've indexed

- **Expose an MCP server** at `http://localhost:8787/mcp/sse` for compatible tools

- **Run it for a team** on a shared machine and point everyone's MCP config at it

See the full product docs at **[linggen.dev](https://linggen.dev)**.

## Install (App)

- Download the latest macOS build from GitHub Releases:

  `https://github.com/linggen/linggen-releases/releases`

- Open the `.dmg` and drag **Linggen** into `Applications`.

- On first launch, it downloads an embedding model (~100MB) and starts a local backend at `http://localhost:8787`.

> Currently macOS only. Windows & Linux are planned.

## MCP Setup (Cursor)

Linggen starts an MCP server at `http://localhost:8787/mcp/sse`.

Add this to `~/.cursor/mcp.json` to connect Cursor:

```json
{
  "mcpServers": {
    "linggen": {
      "url": "http://localhost:8787/mcp/sse"
    }
  }
}
```

Restart Cursor and you should see `linggen` as a connected MCP server.
