Claude Code

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

Then set your token: ``bash export POLYDEV_USER_TOKEN="pd_your_token_here" ``

Or add to ~/.claude.json:

{
  "mcpServers": {
    "polydev": {
      "command": "npx",
      "args": ["-y", "polydev-ai@latest"],
      "env": {
        "POLYDEV_USER_TOKEN": "pd_your_token_here"
      }
    }
  }
}

Cursor

Add to ~/.cursor/mcp.json:

{
  "mcpServers": {
    "polydev": {
      "command": "npx",
      "args": ["-y", "polydev-ai@latest"],
      "env": {
        "POLYDEV_USER_TOKEN": "pd_your_token_here"
      }
    }
  }
}

Windsurf

Add to your MCP configuration:

{
  "mcpServers": {
    "polydev": {
      "command": "npx",
      "args": ["-y", "polydev-ai@latest"],
      "env": {
        "POLYDEV_USER_TOKEN": "pd_your_token_here"
      }
    }
  }
}

Cline (VS Code)

Open Cline settings (gear icon)
Go to "MCP Servers" → "Configure"
Add the same JSON config as above

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

Usage

Natural Language

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 polydev to review this API for security issues"

MCP Tool

Call the get_perspectives tool directly:

{
  "tool": "get_perspectives",
  "arguments": {
    "prompt": "How should I optimize this database query?",
    "user_token": "pd_your_token_here"
  }
}

Example Response

🤖 Multi-Model Analysis

┌─ GPT 5.2 ────────────────────────────────────────
│ The N+1 query pattern is causing performance issues.
│ Consider using eager loading or batch queries...
└──────────────────────────────────────────────────

┌─ Claude Opus 4.5 ────────────────────────────────
│ Looking at the execution plan, the table scan on
│ `users` suggests a missing index on `email`...
└──────────────────────────────────────────────────

┌─ Gemini 3 ───────────────────────────────────────
│ The query could benefit from denormalization for
│ this read-heavy access pattern...
└──────────────────────────────────────────────────

┌─ Grok 4.1 ───────────────────────────────────────
│ Just add an index. The real problem is you're
│ querying in a loop - fix that first.
└──────────────────────────────────────────────────

✅ Consensus: Add index on users.email, fix N+1 query
💡 Recommendation: Use eager loading with proper indexing
