Cc Marketplace — agentic threat model
Cc Marketplace presents a high supply-chain risk as an unvetted repository of community-contributed Claude Code plugins, agents, and commands. Compromise of a single popular plugin could lead to arbitrary code execution and credential theft on developer workstations.

Scored with the canonical OWASP AIVSS formula (AIVSS calculator reference); agentic risk factors estimated from the agent’s described capabilities.
MAESTRO 7-layer threat model
Per-layer threats for this agent. Layers tagged “not certain from listing” are general, caveated commentary where the public description didn’t pin that layer.
Not certain from the listing — The marketplace distributes plugins for Claude Code, but the specific underlying foundation models used by these 17 agents and their alignment/adversarial protections are not detailed.
Not certain from the listing — The data operations, vector stores, or knowledge bases utilized by the individual hosted agents are not specified in this directory entry.
The marketplace hosts 17 agents, 40 commands, and lifecycle hooks. This introduces significant risk of insecure tool integration, malicious command execution, and framework-level vulnerabilities within the Claude Code environment.
Not certain from the listing — The execution environment (e.g., local developer machine vs. sandboxed container) and secrets management for these plugins are dependent on the user's local Claude Code setup.
Not certain from the listing — There is no mention of built-in evaluation, monitoring, or logging guardrails to detect anomalous or malicious behavior of the installed plugins.
As a free, open-source community marketplace, there is a lack of visible security compliance controls, code signing, or automated vulnerability scanning for the 119 hosted plugins.
The core value proposition is a multi-agent and plugin ecosystem. This creates a high exposure to rogue or compromised agents, malicious lifecycle hooks, and cascading failures across interconnected community tools.
