Our reading of Precept, from the data
Precept is an MCP server from johnbabat, listed in the official MCP Registry.
Its endpoint requires sign-in or an API key just to list tools, so we haven't measured its token cost; we never use real credentials.
Maintenance is active: the last public signal was in the last day (2026-10-17).
It runs either locally over stdio or as a hosted endpoint and needs one secret (PRECEPT_API_KEY); use a scoped, least-privilege key.
