What Sanctum Runtime is

Sanctum Runtime is middleware that checks proposed actions from AI agents, robots, automation, and other embodied systems before they are carried out. It evaluates actions against policies and can approve them, request verification, or block them. Operators can review, approve, deny, or escalate actions using web and mobile workflows. For runtime visibility and incident review, it describes behavioral monitoring, audit logs, policy history, and decision trails. Its open-core runtime supports local policy checks and offline heuristics, including risk scoring with local Ollama. Developers can connect through a Node SDK, an agent adapter, an MCP wrapper, or a hosted OpenAI-compatible proxy. Listed integrations include OpenAI, Claude/MCP, Gemini-style function calling, DeepSeek, Grok, Bedrock-compatible endpoints, NVIDIA NIM, custom agents, and local runtimes. Robotics materials include Python SDK support, ROS2-oriented policy packs, and smart-home and embodied-agent templates. Sanctum is MIT-licensed and self-hostable, with a hosted console also available. It is embedded runtime middleware rather than a standalone consumer app or robot controller; some enterprise capabilities are private. A free plan is listed.

Who it suits

It suits agent startups, platform and AI engineers, and security or compliance teams that need controls around agent actions. Robotics and automation teams may also find its listed SDKs, policy packs, and templates relevant.

What it does well

  • Can approve, verify, or block actions against policies
  • Web and mobile workflows for operator review
  • Supports local policy checks and offline heuristics
  • Self-hostable under an MIT license
  • Lists Python SDK and ROS2-oriented policy packs

What to know first

  • Not a standalone consumer app or robot controller
  • Some enterprise capabilities are private

Getting started

  1. Open https://www.sanctumruntime.com/.
  2. Choose the hosted console or self-host the MIT-licensed repository.
  3. Install the Node SDK for developer access.
  4. Connect an agent through the adapter, MCP wrapper or hosted OpenAI-compatible proxy.
  5. Configure policy checks and operator review workflows for web or mobile.

Verdict

Sanctum Runtime is aimed at teams that need policy checks and operator oversight between AI reasoning and execution. Its free plan, self-hosting option, offline checks, and range of documented integrations provide several deployment paths, but it is middleware rather than a complete end-user product.
