MCP Servers

kairo

Autonomously analyzes projects, generates Playwright tests via OpenAI, runs them, classifies failures, and recommends fixes, iterating up to 3 times.

README

Kairo

Kairo is an MCP server that closes the loop between code generation and test verification.

It autonomously analyzes a project → generates Playwright tests via OpenAI → runs them → classifies failures → recommends fixes — iterating up to 3 times.

How it works

analyze → generate tests → run → classify → fix → rerun (max 3x)

Exit conditions: all pass · iteration 3 reached · only flaky/env failures · app unresponsive

Install

npm install -g @kairo/mcp

Or use via npx (no install needed):

{
  "mcpServers": {
    "kairo": {
      "command": "npx",
      "args": ["-y", "@kairo/mcp"],
      "env": {
        "OPENAI_API_KEY": "sk-..."
      }
    }
  }
}
