Vibe Check Mcp Server

pv-bhat/vibe-check-mcp-server

Vibe Check MCP provides agent oversight and safety monitoring through a research-backed mentoring layer that interrupts overzealous AI agent behavior. The server offers chain-pattern interrupt capabilities designed to keep agents aligned and reflective, with research indicating it improves agent success rates by 27% while reducing harmful actions by 41%. It operates via STDIO and streamable HTTP transport, serving as a plug-and-play tool for preventing agents from over-engineering solutions and maintaining minimal viable execution paths.
