About crypt-r
crypt-r is an MCP server published by INFORMERadm in the Other category.
Six months or more without a commit doesn't mean the server is broken, but check the open issues before depending on it in production.
Install
git clone https://github.com/INFORMERadm/crypt-rThis server has no ConduID identity, so agent calls to it are not receipted. Pin the version you install and review the source before granting it credentials.
