LABSCO SUMMARY

A different model with different training, one call away.

When an assistant is confidently wrong, more turns with the same model rarely help. Pulling three sources with genuinely different failure modes — another model, live web results, and human-accepted answers — is the useful shape, and the git-aware context means you do not have to paste the surrounding files yourself.

What it is

An MCP server that combines three different sources — a second model, web-grounded search, and accepted answers from real engineers — into one synthesised answer, so you can unblock a stuck conversation without switching apps.

What you get

  • Multi-source synthesis: Google Gemini for an alternative model perspective, Perplexity for fresh web-grounded analysis, Stack Overflow for accepted answers
  • Automatic language detection from file extensions, and code snippet extraction with clean formatting
  • Git-aware context gathering that pulls in nearby files when relevant
  • Markdown report generation for the solution
  • One tool call, so the model gathers your code and context and returns a combined take

Requirements

TypeScript and Node.js 18+. Clone, npm install, npm run build, then register node build/index.js in claude_desktop_config.json. Two keys are required: GEMINI_API_KEY from aistudio.google.com and PERPLEXITY_API_KEY from perplexity.ai. STACK_EXCHANGE_KEY is optional — without it the Stack Exchange calls fall back to anonymous. Restart Claude Desktop after adding the config. MIT.

Setup effort

Build from source — git clone https://github.com/joewilsonai/second-opinion-mcp-server
