This project is in maintenance mode. Active feature development has ended; only maintenance patches (security and bug fixes) are published. v2.9.0 is the latest maintenance release. The server remains fully functional. Community forks and contributions are welcome under the MIT license.
KISS overzealous agents goodbye. Plug & play agent oversight tool.
Based on research: In our study agents calling Vibe Check improved success +27% and halved harmful actions -41%
Featured on PulseMCP “Most Popular (This Week)” • 5k+ monthly calls on Smithery.ai • research-backed oversight • STDIO + streamable HTTP transport
Plug-and-play mentor layer that stops agents from over-engineering and keeps them on the minimal viable path — research-backed MCP server keeping LLMs aligned, reflective and safe.
Trusted by developers across MCP platforms and registries
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
- Launch from an MCP-aware client (Claude Desktop, Cursor, Windsurf, etc.).
[MCP] stdio transport connectedindicates the process is waiting for the client.- Add this block to your client config so it spawns the command:
{
"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
curl http://127.0.0.1:2091/healthzto confirm the service is live.- Send JSON-RPC requests to
http://127.0.0.1:2091/mcp.
npx downloads the package on demand for both options. For detailed client setup and other commands like install and doctor, see the documentation below.
