What is ADR?

What it is

ADR is an open-source enterprise security system for AI agents. It is built in Python under the Apache-2.0 license and lives in the AI security and privacy ecosystem. It targets employee-facing coding agents such as Cursor, Claude Code, Codex, GitHub Copilot CLI, and DeepSeek Harness, and customer-facing agents such as AI support agents.

The problem is that agents can call tools, use MCP servers, execute commands, and act on user intent, creating risk from misuse, compromise, or prompt injection. ADR addresses this by discovering AI tools on endpoints, observing agent activity, benchmarking defenses, and detecting risky behavior. The repository states that ADR is deployed in production at Uber and that the paper was accepted to MLSys 2026.

Key capabilities

  • ADR Discovery inventories installed AI applications, CLI agents, IDE extensions, local model runtimes, and MCP servers, then flags unknown surfaces for review.
  • ADR Observability captures agent intent, tool use, and execution traces across more than seven AI coding tools on macOS, Linux, and Windows.
  • ADR Sensor collects and normalizes telemetry from Claude Code, Cursor, Codex, GitHub Copilot CLI, DeepSeek Harness, opencode, Claude Desktop, and other agents.
  • ADR-Bench evaluates agent security with more than 300 tasks, 134 MCP servers, and coverage of all 17 agent attack techniques listed in the README.
  • ADR Detection uses a two-tier architecture that combines high-recall triage with deeper agentic reasoning for suspicious sessions.

Who uses it and how

  • Organizations can use ADR Discovery to inventory AI tools on employee endpoints and identify unsanctioned or unknown agent surfaces.
  • Engineering teams can use ADR Sensor to collect normalized telemetry from coding and support agents, showing what tools an agent used and why.
  • Researchers and security teams can run ADR-Bench to test detectors under enterprise-like conditions, including MCP servers and prompt injection attacks.

Getting started

Clone https://github.com/uber/ADR, enter the Detection directory, run uv sync, and set ANTHROPIC_API_KEY and OPENAI_API_KEY. The README points to docs/REPRODUCIBILITY.md for the full evaluation workflow.

When to use it — and when not to

ADR is useful when an organization needs open-source components for discovering, observing, benchmarking, and detecting agentic AI risk around coding agents and MCP servers. It is not a complete prevention system in this release, because ADR Prevention and the offline ADR Explorer engine are excluded. The repository is new, with no listed contributors and six open issues, so adopters should expect an early-stage project rather than a mature productized platform.

ADR: Agentic AI Detection and Response

uber/ADR | Trendshift

ADR (Agentic AI Detection and Response) is an enterprise security system for AI agents. It helps organizations secure employee-facing agents such as Cursor, Claude Code, Codex, GitHub Copilot CLI, and DeepSeek Harness, as well as customer-facing agents such as AI support agents.

ADR is deployed in production at Uber, and the accompanying paper was accepted to MLSys 2026: Paper PDF · Slides PDF

How ADR secures enterprise AI agents

ADR secures enterprise AI agents through five complementary capabilities: discovering unsanctioned AI tools, observing agent activity, evaluating defenses, detecting threats, and preventing unsafe actions.

  1. ADR Discovery: Find the AI tools present on employee endpoints. Inventories installed AI applications, CLI agents, IDE extensions, local model runtimes, and MCP servers, and flags unknown surfaces for review.
  2. ADR Observability: Understand what AI agents are doing and why. In production, ADR captures agent intent, tool use, and execution traces across 7+ AI coding tools on macOS, Linux, and Windows, as well as internal automation and customer-facing support agents.
  3. ADR Benchmark: Test agent security under realistic enterprise conditions. ADR-Bench includes 300+ tasks, 134 MCP servers, and coverage of all 17 agent attack techniques.
  4. ADR Detection: Detect risky agent behavior efficiently. Its two-tier architecture combines high-recall triage with deeper agentic reasoning for suspicious sessions.
  5. ADR Prevention: Stop unsafe actions before they cause harm. This component is not included in the current open-source release. Stay tuned.

Repository layout

This repository contains the open-source ADR Discovery, ADR Sensor, ADR-Bench, and ADR Detector described in the paper. The offline ADR Explorer engine, which hardens ADR Detection through pre-deployment red teaming, is not included here.

Path ADR component Description
Discovery/ ADR Discovery Inventory the AI apps, CLI agents, IDE extensions, model runtimes, and MCP servers on an endpoint, and flag unknown surfaces for review
Sensor/ ADR Observability Collect and normalize agent telemetry from Claude Code, Cursor, Codex, GitHub Copilot CLI, DeepSeek Harness, opencode, Claude Desktop, and others
Detection/ ADR Benchmark + Detection Dual-agent detector, 134 MCP servers, 304 benchmark tasks, baselines, figure scripts

Quick start: ADR Detection

git clone https://github.com/uber/ADR
cd ADR/Detection
uv sync
export ANTHROPIC_API_KEY="..." OPENAI_API_KEY="..."

Default detector is adr (ADR dual-agent). For keyless smoke tests, use --detector llamafirewall (see Detection/README.md).

See docs/REPRODUCIBILITY.md for the full evaluation workflow (inflate packed benchmark → run detectors → plot figures).
