Verdict

Pick Open Code Review if you prefer its approach (ai code quality gate that detects hallucinated imports, stale apis, over-engineering, and security anti-patterns in ai-generated code).

Pick Serena if you prefer the more popular, battle-tested option, and you need the broadest set of tools.

Add Open Code Review

Install / run
npx -y @opencodereview/mcp-server

Paste into ~/Library/Application Support/Claude/claude_desktop_config.json

{
  "mcpServers": {
    "open-code-review": {
      "command": "npx",
      "args": [
        "-y",
        "@opencodereview/mcp-server"
      ]
    }
  }
}

Add Serena

Install / run
uvx --from git+https://github.com/oraios/serena serena start-mcp-server

Paste into ~/Library/Application Support/Claude/claude_desktop_config.json

{
  "mcpServers": {
    "serena": {
      "command": "uvx",
      "args": [
        "--from",
        "git+https://github.com/oraios/serena",
        "serena",
        "start-mcp-server"
      ]
    }
  }
