From the repository

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.

Edit your claude_desktop_config.json:

{
  "mcpServers": {
    "second-opinion": {
      "command": "node",
      "args": ["/absolute/path/to/second-opinion-mcp-server/build/index.js"],
      "env": {
        "GEMINI_API_KEY": "your-gemini-api-key",
        "PERPLEXITY_API_KEY": "your-perplexity-api-key",
        "STACK_EXCHANGE_KEY": "your-stack-exchange-key"
      }
    }
  }
}

Restart Claude Desktop.

🧠 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.

</div>

---

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

Install

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

Configure in Claude Desktop

Edit your claude_desktop_config.json:

{
  "mcpServers": {
    "second-opinion": {
      "command": "node",
      "args": ["/absolute/path/to/second-opinion-mcp-server/build/index.js"],
      "env": {
        "GEMINI_API_KEY": "your-gemini-api-key",
        "PERPLEXITY_API_KEY": "your-perplexity-api-key",

      }
    }
  }
}

Restart Claude Desktop.
