Vibe Check is an AI agent oversight and safety tool that prevents over-engineering and misalignment by injecting Socratic checkpoints into agent reasoning workflows. Based on Chain-Pattern Interrupt (CPI) research, it acts as a metacognitive guardrail to keep AI agents aligned, reflective, and on the minimal viable path. Key features: - Chain-Pattern Interrupts (CPI) that pause agent execution to check for scope creep, over-engineering, and misalignment through Socratic questioning - Support for Gemini API, OpenRouter, and OpenAI models - Error logging and continuous improvement capabilities for oversight workflows - Research-backed approach demonstrating 27% improvement in agent success rates and 41% reduction in harmful actions - Compatible with STDIO and streamable HTTP transports for flexible integration into agent development stacks

Quickstart (npx)

Run the server directly from npm without a local installation. Requires Node >=20. Choose a transport:

Option 1 – MCP client over STDIO

npx -y @pv-bhat/vibe-check-mcp start --stdio

{
  "mcpServers": {
    "vibe-check-mcp": {
      "command": "npx",
      "args": ["-y", "@pv-bhat/vibe-check-mcp", "start", "--stdio"]
    }
  }
}

Option 2 – Manual HTTP inspection

npx -y @pv-bhat/vibe-check-mcp start --http --port 2091

npx downloads the package on demand for both options. For detailed client setup and other commands like install and doctor, see the documentation below.
