Asymmetric Tool Surfaces for AI-Agent Cryptographic Primitives

We argue that SDKs exposing cryptographic primitives to autonomous AI agents must obey an explicit asymmetry rule: read and pure-compute operations may be exposed without privilege, but state-changing authority must remain behind an out-of-band human or hardware confirmation. We formalise this rule, instantiate it for a shielded-pool zero-knowledge SDK exposing its surface via the Model Context…
