# From source

> Build and run the Peaka MCP server from a local clone of the GitHub repository.

For contributors and users who need to run a modified or pinned build, the server can be cloned from GitHub and run from source.

For most users, [Remote](/mcp/install/remote) or [NPM](/mcp/install/npm) is simpler.

## Prerequisites

* Node.js 18 or newer.
* A Peaka API key — see [Authentication](/mcp/authentication).

## Clone and build

```bash theme={null}
git clone https://github.com/peakacom/peaka-mcp-server.git
cd peaka-mcp-server
npm install
npm run build
```

The build emits `dist/index.js`, which is the binary your client will launch.

## Configure your client

Point your client at the local build and pass the API key as an environment variable:

```json theme={null}
{
  "mcpServers": {
    "peaka": {
      "command": "node",
      "args": ["/absolute/path/to/peaka-mcp-server/dist/index.js"],
      "env": {
        "PEAKA_API_KEY": "<YOUR_API_KEY>"
      }
    }
  }
}
```

Use an absolute path. Restart the client after editing its config.

## Environment variables

| Name            | Description                                                             |
| --------------- | ----------------------------------------------------------------------- |
| `PEAKA_API_KEY` | Project or Partner API key for authenticating with Peaka. **Required.** |

## Updating

Pull the latest changes and rebuild:

```bash theme={null}
git pull
npm install
npm run build
```

Your client will pick up the new binary on its next launch of the server.
