Polydev

🚀 Polydev

Multi-model AI perspectives for your coding agents. Query GPT-5, Claude, Gemini, and Grok simultaneously through one MCP server.

🚀 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

✨ Features

• One-Request Multi-Model Query: Stop copy-pasting between ChatGPT, Claude, and Gemini. Get all their perspectives in your IDE with one request.
• Cost-Effective: Our approach achieves 74.6% on SWE - bench Verified (Resolve@2), matching Claude Opus at 62% lower cost.
• Fast Response: Response time is 10 - 40 seconds.
• Use Existing Subscriptions: Use your existing ChatGPT Plus, Claude Pro, or Gemini Advanced subscriptions directly through your CLI tools.

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
