Our reading of Otx, from the data

Otx is a security MCP server from w0h1v, listed in the official MCP Registry.

We haven't measured its tool list yet, so its token cost is unknown.

With 1 GitHub stars it ranks #409 of 1,263 security servers we index.

It runs locally on your machine over stdio and needs one secret (OTX_API_KEY); use a scoped, least-privilege key.
