Overview

Description from the maker (original English)

Any model in any agent: ask several AI models the same question and compare the answers. Free.

PopNx MCP’s three pillars

These three are never merged into one score: opinions, measurements and popularity are different things.

What you can do with it

We have not written a plain-language summary for this one yet. Below are the facts we read from the registry.

  • Connection: Computer or cloud
  • Transport: stdio, Streamable HTTP
  • Category: Other
  • You need to fill in: POLYDEV_USER_TOKEN

Install

Pick the AI app you use, then copy the settings.

Before you install

  • Basic checks: 2 of 3 passed
  • Runs on the maker’s server: what you ask it goes through their server.
  • You fill in yourself: POLYDEV_USER_TOKEN

Values marked secret are keys to your account. Never share them or paste them into a chat.

You need

  • Runs in the cloudNothing to install; it connects over the internet
  • npmNode.js installed (for the npx command)

Which app do you use?

Pick your app above. We remember it, so next time the button says “Install in …”.

Works in Claude on the web, desktop and mobile:

  1. Open Settings → Connectors
  2. Press Add custom connector
  3. Paste the address below and press Add
  4. If it asks you to sign in, sign in with the maker

Or run it on your computer

Open Claude Desktop → Settings → Developer → Edit Config, and paste this into claude_desktop_config.json

ChatGPT connects only to servers on the internet:

  1. Open ChatGPT on the web → Settings → Connectors (Apps)
  2. Press Create or Add (some plans need Developer mode under Advanced first)
  3. Paste the address below, give it a name and save
  4. If it asks you to sign in, sign in with the maker
SettingsConnectors1+ Create2https://…3
https://polydev.ai/mcp

Menu names can differ slightly by plan and over time.

Your choice stays on this device in a cookie; no account needed.

Values you fill in

  • POLYDEV_USER_TOKEN secret env
    Your Polydev token (starts with pd_). Optional: the first call opens the browser to sign in and saves it. Tokens: https://polydev.ai/dashboard/mcp-tokens

These settings are generated from the maker’s registry entry. If the README says otherwise, follow the README.

What it can do

The server asks you to sign in before it lists its tools.

Basic checksi

We check information anyone can see; we have not read the code. Checks that do not apply are left out of the count. · Checked Nov 7, 2026

  • ! Caution

    Maker matches the repo

    The publisher (polydev-ai) is not the repo owner (polydev-ai); someone else may have listed it

  • … Not checked yet

    Still maintained

    We have not read this repo from GitHub yet

  • … Not checked yet

    We have not read this repo from GitHub yet

  • ✓ Pass

    Endpoint responds

    Responded in 695 ms (HTTP 401)

  • ✓ Pass

    Sign-in with OAuth

    Declares OAuth sign-in, so your AI app can take you to log in

  • … Not checked yet

    No hidden instructions in tool descriptions

Compared with others in Otheri

  • More stars than 0% of the other 32655 servers in this category
  • Published to the registry more recently than 97% of the other 32655 servers in this category
  • Basic checks equal to or better than 37% of the other 32655 servers in this category

Compared with every active server in this category in the registry. Stars count only when the publisher owns the repo.

Common questions

Is Polydev safe?

It passed 2 of 3 applicable basic checks. We have not read the code. Before adding a key or token, see what access the server asks for and use a key with only the permissions you need.

What keys or codes does it need?

You need to fill in: POLYDEV_USER_TOKEN

Does it run on my computer or in the cloud?

Either way works: install it on your computer or connect to the cloud version.

Is it still maintained?

The GitHub repo last changed –, and the latest version (1.11.0) reached the registry yesterday.

Which apps can use it?

Apps that support MCP, such as Claude Desktop, Claude Code, Cursor and VS Code. It connects by URL, so apps that accept remote MCP servers work too, such as ChatGPT in developer mode.

What can I use instead?

In the same category: Spec Driven Development, Remote Desktop Commander, SuperCollider

Polydev

Multi-model AI perspectives for your coding agents

Query GPT-5, Claude, Gemini, and Grok simultaneously through one MCP server


🚀 One-Command Install

Claude Code
claude mcp add polydev -- npx -y polydev-ai@latest
Cursor / Windsurf / Cline
npx polydev-ai@latest
OpenAI Codex CLI
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.

MetricResult
SWE-bench Verified74.6% Resolve@2
Cost vs Claude Opus62% lower
Response time10-40 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

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.

SubscriptionCLI ToolSetup
Claude Pro ($20/mo)Claude Codeclaude login
ChatGPT Plus ($20/mo)Codex CLIcodex login
Gemini Advanced ($20/mo)Gemini CLIgemini 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.
