Cursor / Windsurf / Cline
npx polydev-ai@latest
OpenAI Codex CLI
npx polydev-ai@latest
Get your token at 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
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.
| 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:
# 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
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 |
