The record

Purpose: Sanctum is a runtime trust layer between AI reasoning and real-world execution for agents, robotics, automation, and embodied systems.
Action controls: It evaluates actions against policies and can approve, require verification, or block them before execution.
Human approvals: Operators can review, approve, deny, or escalate actions through web and mobile review workflows.
Monitoring and audit: Sanctum describes behavioral monitoring, audit logs, policy history, and decision trails for runtime visibility and incident review.
Offline operation: The open-core runtime supports local policy checks and offline heuristics, including local Ollama risk scoring.
Integrations: The documented verify path supports OpenAI, Claude/MCP, Gemini-style function calling, DeepSeek, Grok, Bedrock-compatible endpoints, NVIDIA NIM, custom agents, and local runtimes.
Developer access: Developers can install the Node SDK and use an agent adapter, an MCP wrapper, or a hosted OpenAI-compatible proxy.
Robotics support: The documentation lists Python SDK support, ROS2-oriented policy packs, and smart-home and embodied-agent templates.
Security mechanisms: The documented security layer includes signed agent and action tokens, short-lived approvals, source-trust context, blast-radius scoring, audit-chain verification, and encrypted platform keys.
License and deployment: The repository is described as MIT-licensed and self-hostable; the product also offers a hosted console, while some enterprise capabilities are private.
Limits: Sanctum describes itself as embedded runtime middleware, not a standalone consumer app or robot controller.
Intended users: The site presents the product for agent startups, platform and AI engineers, and security or compliance teams.
