The skill is a coherent agent-messaging tool, but it needs review because an MCP tool can pull/install and run server software, remove Docker containers on the target port, and leave a local service running without a separate approval step.
Install only if you intentionally want agents to communicate through a keep server. Pin package, image, or Go module versions before use; do not let an agent call keep_ensure_server unless you are comfortable with Docker/Go running code locally; keep the service bound to trusted local networks; monitor and stop the container or background process when finished; and do not send secrets or unreviewed memory through agent messages.
