Connects Claude (and other MCP clients) to GPT 5.2, Claude Opus 4.5, Gemini 3, and Grok 4.1 simultaneously through a single API call. Instead of copy-pasting prompts across ChatGPT, Claude, and Gemini web UIs, you get all four perspectives back in your IDE with the get_perspectives tool. Requires a Polydev API token (free tier: 1,000 messages/month). Their SWE-bench Verified testing shows 74.6% resolution using a Resolve@2 approach with Claude Haiku plus Polydev consultation, matching Opus performance at 62% lower cost. Useful when you're genuinely stuck and want to see how different models approach the same problem without the context-switching overhead.
