### Description (declared)

# Second Opinion MCP

Get independent AI reviews from Claude Code, DeepSeek V4 Pro, Kimi K3 (Moonshot), OpenAI (ChatGPT), and 300+ OpenRouter models through any MCP client.

## What It Does

When working with Codex, Claude Code, Claude Desktop, or another MCP client, this server lets you:

- Get alternative perspectives on code, architecture, and decisions
- Run systematic code reviews with severity-classified issues
- Stage multi-model debates where AI models argue opposing positions
- Challenge proposals with anti-sycophancy mode (finds weaknesses, not validation)
- Review architectural plans before coding begins
- Review implementations against their original plans

## Quickstart

### 1. Install

#### Windows

```powershell
# Install Python 3.10+ from python.org if not installed
# Then install pipx
pip install pipx
pipx ensurepath

# Restart your terminal, then install
pipx install second-opinion-mcp
```

#### macOS

```bash
# Install Python 3.10+ via Homebrew if not installed
brew install python@3.12

# Install pipx
pip3 install pipx
pipx ensurepath

# Restart your terminal, then install
pipx install second-opinion-mcp
```

#### Linux (Ubuntu/Debian)

```bash
# Install Python and pipx
sudo apt update
sudo apt install python3 python3-pip python3-venv
pip3 install pipx
pipx ensurepath

# Restart your terminal, then install
pipx install second-opinion-mcp
```

#### Linux (Fedora/RHEL)

```bash
sudo dnf install python3 python3-pip
pip3 install pipx
pipx ensurepath

# Restart your terminal, then install
pipx install second-opinion-mcp
```

### 2. Setup

Run the interactive setup wizard:

```bash
second-opinion-mcp setup
```

The wizard will guide you through selecting providers and entering API keys. Keys are stored securely in your system's credential manager.

The wizard automatically verifies your setup when it finishes. To re-check later:

```bash
second-opinion-mcp verify
```

After setup completes, see Client Integration below for instructions specific to your…
