AI Agent Tools
MITRE source definition
Adversaries may create and publish poisoned AI agent tools. Poisoned tools may contain malicious model-visible definitions or instructions, hidden executable behavior, or runtime responses designed to manipulate an AI agent. Tools may be published through source code repositories, package registries, agent tool or skill registries, or adversary-controlled remote services. The tool may be newly created or a modified variant of a legitimate tool and may produce malicious behavior when selected, installed, or invoked by a victim's AI agent.
Adversaries may distribute poisoned tools through open-source version control repositories (e.g. GitHub, GitLab), package registries (e.g. npm), or to repositories specifically designed for sharing tools (e.g. OpenClaw Hub). These registries may be largely unregulated and may contain many poisoned tools [[opensourcemalware]]. Tools may also be published as remotely hosted servers [[mcpservers]].

Simulation and telemetry boundary
This is a technique reference page, not a runnable simulation. No ATLAS-specific telemetry mapping, local attack execution or detector validation is asserted. MITRE maturity describes its source evidence, not a 1200km lab result.
For broader context—not technique-specific control mappings—see AI Security, AI Security Course, and detection-validation methodology.
