## About

# Grok2API MCP Server

**English** · [中文](./README.zh-CN.md)

An [MCP (Model Context Protocol)](https://modelcontextprotocol.io/) server that provides real-time web search via [Grok](https://x.ai/grok). Returns structured results with source URLs, confidence scores, key points, and multi-language support.

## How It Works

```
Claude / Cursor / etc.  ──MCP──>  grok-mcp-server  ──HTTP──>  grok2api  ──>  Grok
```

This server bridges MCP clients to a [grok2api](https://github.com/chenyme/grok2api)-compatible backend, exposing Grok's real-time web search through an OpenAI-compatible API.

## Features

- **Real-time web & Twitter/X search** via Grok
- **Structured JSON output** — summary, key points with citations, source list, confidence score
- **Multiple output modes** — `brief`, `analyst`, `raw`
- **Multi-language support** — respond in any language
- **Time range filtering** — `24h`, `7d`, `30d`, `all`
- **Source freshness control** — prefer recent sources
- **Domain allowlist preference** — prioritize trusted domains (best-effort)
- **Automatic retries** with exponential backoff
- **Runtime metrics** via `grok_stats` tool

## Prerequisites

You need a running [grok2api](https://github.com/chenyme/grok2api) instance (or any OpenAI-compatible API endpoint backed by a Grok model with web search).

## Setting Up the grok2api Backend

> **It is strongly recommended to use a secondary/alt Grok account for this, not your primary account.**

### 1. Deploy grok2api

Choose the method that fits your environment:

VPS / Server (Docker Compose — recommended)

Requires [Docker](https://docs.docker.com/get-docker/) and Docker Compose installed on your server.

```bash
git clone https://github.com/chenyme/grok2api
cd grok2api
docker compose up -d
```

The admin panel will be available at `http://your-server-ip:8000/admin` (default password: `grok2api`).

macOS (local)

Requires Python 3.11+ and [uv](https://docs.astral.sh/uv/).

```bash
# Install uv if you don't have it
brew install uv

# Clone and run
git clone https://github.com/chenyme/grok2api
cd grok2api
uv sync
uv run main.py
```

The admin panel will be at `http://localhost:8000/admin` (default password: `grok2api`).

Windows (local)

Requires Python 3.11+ and [uv](https://docs.astral.sh/uv/).

```powershell
# Install uv (PowerShell)
powershell -ExecutionPolicy ByPass -c "irm https://astral.sh/uv/install.ps1 | iex"

# Clone and run
git clone https://github.com/chenyme/grok2api
cd grok2api
uv sync
uv run main.py
```

The admin panel will be at `http://localhost:8000/admin` (default password: `grok2api`).

Linux (local, without Docker)

Requires Python 3.11+ and [uv](https://docs.astral.sh/uv/).

```bash
# Install uv
curl -LsSf https://astral.sh/uv/install.sh | sh

# Clone and run
git clone https://github.com/chenyme/grok2api
cd grok2api
uv sync
uv run main.py
```

The admin panel will be at `http://localhost:8000/admin` (default password: `grok2api`).

For cloud deployments (Vercel, Render), see the [grok2api README](https://github.com/chenyme/grok2api).

### 2. Get Your Grok Cookie

1. Log into [grok.com](https://grok.com) with your Grok account
2. Open browser DevTools (`F12` or `Cmd+Opt+I`)
3. Go to the **Application** tab
4. In the left sidebar, expand **Storage → Cookies**
5. Find the cookie named `sso` or `sso-rw`
6. Copy its value

### 3. Add Token to grok2api

1. Open the grok2api admin panel (`http://your-server:8000/admin`)
2. Click **Add** to add a new token
3. Paste the cookie value you just copied
4. Select your account type based on your Grok subscription:
   - **Basic** — 80 requests per 20 hours
   - **Super** — 140 requests per 2 hours

The `GROK_API_KEY` in your `.env` is the admin key configured in grok2api (the `app.app_key` value, default: `grok2api`).

## Installation

**Option A: Global install (recommended)**

```bash
git clone https://github.com/wousp112/grok2api-mcp-server.git
cd grok-mcp-server
cp .env.example .env
# Edit .env with your API URL and key
npm install
npm link
```

**Option B: Local install**

```bash
git clone https://github.com/wousp112/grok2api-mcp-server.git
cd grok-mcp-server
cp .env.example .env
# Edit .env with your API URL and key
npm install
```
