🚀 One-Command Install

Claude Code

claude mcp add polydev -- npx -y polydev-ai@latest

Cursor / Windsurf / Cline

npx polydev-ai@latest

OpenAI Codex CLI

Why Polydev?

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

*"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

npx polydev-ai@latest

Step 2: Set your token (get it from polydev.ai/dashboard/mcp-tokens)

export POLYDEV_USER_TOKEN="pd_your_token_here"

Option 2: Self-Host with Your Own API Keys

Step 1: Clone and install

git clone https://github.com/polydev-ai/polydev.git

cd polydev && npm install

Step 2: Configure environment

cp .env.example .env.local

Step 3: Add your API keys to .env.local and run

npm run dev

IDE Configuration

Claude Code

One command:

claude mcp add polydev -- npx -y polydev-ai@latest

Or add to `~/.claude.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):

{

"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`:

[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:

{

"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.

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:

# 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

cd supabase && supabase db push

Run

npm run dev
