## 🚀 One-Command Install

### Claude Code
```sh
claude mcp add polydev -- npx -y polydev-ai@latest
```

### Cursor / Windsurf / Cline
```sh
npx polydev-ai@latest
```

### OpenAI Codex CLI
```sh
npx polydev-ai@latest
```

> Get your token at **[polydev.ai/dashboard/mcp-tokens](https://polydev.ai/dashboard/mcp-tokens)**

---

## Why Polydev?

**Stop copy-pasting between ChatGPT, Claude, and Gemini.** Get all their perspectives in your IDE with one request.

| Metric | Result |
|--------|--------|
| **SWE-bench Verified** | 74.6% Resolve@2 |
| **Cost vs Claude Opus** | 62% lower |
| **Response time** | 10-40 seconds |

> *"Different models have different blind spots. Combining their perspectives eliminates yours."*

---

## How It Works

```
Your Agent → Polydev MCP → [GPT-5, Claude, Gemini, Grok] → Synthesized Answer
```

When your AI agent gets stuck, Polydev consults multiple frontier models simultaneously and returns their combined perspectives. One request, four expert opinions.

---

## Quick Start

### Option 1: Use Hosted Service (Recommended)

Get started instantly at **[polydev.ai](https://polydev.ai)**

**Step 1:** Install the MCP server
```sh
npx polydev-ai@latest
```

**Step 2:** Set your token (get it from [polydev.ai/dashboard/mcp-tokens](https://polydev.ai/dashboard/mcp-tokens))
```sh
export POLYDEV_USER_TOKEN="pd_your_token_here"
```

### Option 2: Self-Host with Your Own API Keys

**Step 1:** Clone and install
```sh
git clone https://github.com/polydev-ai/polydev.git
```
```sh
cd polydev && npm install
```

**Step 2:** Configure environment
```sh
cp .env.example .env.local
```

**Step 3:** Add your API keys to `.env.local` and run
```sh
npm run dev
```

---

## IDE Configuration

### Claude Code

**One command:**
```sh
claude mcp add polydev -- npx -y polydev-ai@latest
```

**Or add to `~/.claude.json`:**
```json
{
  "mcpServers": {
    "polydev": {
      "command": "npx",
      "args": ["-y", "polydev-ai@latest"],
      "env": {
        "POLYDEV_USER_TOKEN": "pd_your_token_here"
      }
    }
  }
}
```

### Cursor / Windsurf / Cline

**Add to your MCP config (usually `~/.cursor/mcp.json` or similar):**
```json
{
  "mcpServers": {
    "polydev": {
      "command": "npx",
      "args": ["-y", "polydev-ai@latest"],
      "env": {
        "POLYDEV_USER_TOKEN": "pd_your_token_here"
      }
    }
  }
}
```

### OpenAI Codex CLI

**Add to `~/.codex/config.toml`:**
```toml
[mcp_servers.polydev]
command = "npx"
args = ["-y", "polydev-ai@latest"]

[mcp_servers.polydev.env]
POLYDEV_USER_TOKEN = "pd_your_token_here"

[mcp_servers.polydev.timeouts]
tool_timeout = 180
session_timeout = 600
```

---

## Usage

Once connected, your agent can call:

```json
{
  "tool": "get_perspectives",
  "arguments": {
    "prompt": "How should I refactor this authentication flow?"
  }
}
```

Or just mention "polydev" or "perspectives" in your prompt:

```
"Use polydev to debug this infinite loop"
"Get perspectives on: Should I use Redis or PostgreSQL for caching?"
```

---

## Use Your Existing CLI Subscriptions

**Already paying for ChatGPT Plus, Claude Pro, or Gemini Advanced?** Use those subscriptions directly through your CLI tools.

| Subscription | CLI Tool | Setup |
|--------------|----------|-------|
| Claude Pro ($20/mo) | Claude Code | `claude login` |
| ChatGPT Plus ($20/mo) | Codex CLI | `codex login` |
| Gemini Advanced ($20/mo) | Gemini CLI | `gemini login` |

Polydev can route requests through your authenticated CLI sessions — your subscription quota is used, no extra API costs.

---

## Self-Hosting

### Requirements

- Node.js 18+
- PostgreSQL (or Supabase)
- API keys for the models you want to use

### Environment Variables

Create a `.env.local` file:

```sh
# Database
NEXT_PUBLIC_SUPABASE_URL=your_supabase_url
NEXT_PUBLIC_SUPABASE_ANON_KEY=your_anon_key
SUPABASE_SERVICE_ROLE_KEY=your_service_role_key

# AI Providers (add the ones you want)
OPENAI_API_KEY=sk-...
ANTHROPIC_API_KEY=sk-ant-...
GOOGLE_API_KEY=...
XAI_API_KEY=...
```

### Database Setup

```sh
cd supabase && supabase db push
```

### Run

```sh
npm run dev
```

## Research

Our approach achieves **74.6% on SWE-bench Verified** (Resolve@2), matching Claude Opus at 62% lower cost.

| Approach | Resolution Rate | Cost/Instance |
|----------|-----------------|---------------|
| Claude Haiku (baseline) | 64.6% | $0.18 |
| + Polydev consultation | 66.6% | $0.24 |
| **Resolve@2 (best of both)** | **74.6%** | $0.37 |
| Claude Opus (reference) | 74.4% | $0.97 |
