🧠 Second Opinion MCP Server

Stuck on a problem? Get a second opinion from a different model.

An MCP server that combines Gemini, Perplexity, and Stack Overflow to give Claude (or any MCP client) a multi-source second take on tough coding problems.

Why

When Claude gets stuck — or just confidently wrong — the fastest unblocker is a different model with different training. This server makes that one tool call away:

  • 🟦 Google Gemini for an alternative model perspective
  • 🟪 Perplexity for fresh web-grounded analysis
  • 🟧 Stack Overflow for accepted answers from real engineers

You stay in your Claude conversation. The second opinion comes to you.

Features

  • 🌐 Multi-source synthesis — combines insights from three different sources into one answer
  • 🔤 Automatic language detection from file extensions
  • 📋 Code snippet extraction and clean formatting
  • 📄 Markdown report generation for solutions
  • 🧠 Git-aware context gathering — includes nearby files when relevant
  • ⚡ Single tool call — no need to context-switch between chat apps

Install

git clone https://github.com/joewilsonai/second-opinion-mcp-server
cd second-opinion-mcp-server
npm install

Usage

Once installed, just ask Claude:

"Get a second opinion on this race condition I'm hitting in our worker pool."

Claude will call the tool, pass your code + context, and synthesize a response from all three sources.
