Spec Driven Development
MCP Server that facilitates spec-driven development workflows, not just Vibe Coding.
Description from the maker (original English)
Any model in any agent: ask several AI models the same question and compare the answers. Free.
These three are never merged into one score: opinions, measurements and popularity are different things.
We have not written a plain-language summary for this one yet. Below are the facts we read from the registry.
Pick the AI app you use, then copy the settings.
POLYDEV_USER_TOKENValues marked secret are keys to your account. Never share them or paste them into a chat.

These settings are generated from the maker’s registry entry. If the README says otherwise, follow the README.
The server asks you to sign in before it lists its tools.

Compared with every active server in this category in the registry. Stars count only when the publisher owns the repo.
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.
You need to fill in: POLYDEV_USER_TOKEN
Either way works: install it on your computer or connect to the cloud version.
The GitHub repo last changed –, and the latest version (1.11.0) reached the registry yesterday.
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.

Multi-model AI perspectives for your coding agents
Query GPT-5, Claude, Gemini, and Grok simultaneously through one MCP server
claude mcp add polydev -- npx -y polydev-ai@latest
npx polydev-ai@latest
npx polydev-ai@latest
Get your token at [polydev.ai/dashboard/mcp-tokens](https://polydev.ai/dashboard/mcp-tokens)
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."*
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.
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"
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
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" } } } }
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" } } } }
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
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?"
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.
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
OPENAI_API_KEY=sk-... ANTHROPIC_API_KEY=sk-ant-... GOOGLE_API_KEY=... XAI_API_KEY=...
cd supabase && supabase db push
npm run dev
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 |
