# tool si.act.keep_proxy

a proxy: its name, the facet kind it stands for, its scope, its rule as a predicate, its strength, its named control, its failure mode, and whether it is aggregate-only: the proxy with its version by hash, not ready until its controls have run and its calibration is read.

[figure: Over MCP, si.act.keep_proxy takes KeepProxyInput and returns a card whose body is Proxy.]

the proxy with its version by hash, not ready until its controls have run and its calibration is read. The call needs the act grant at the strategy rung.
