OWASP Agentic AI Security: The Ultimate Guide for 2025

Explore the OWASP agentic AI security tool, designed to protect against vulnerabilities like prompt injection and data leakage, ensuring robust AI agent security.

As artificial intelligence systems become increasingly autonomous and integrated with external tools, a new category of security threats has emerged that traditional cybersecurity approaches cannot adequately address. The OWASP-Agentic-MCP 1.0.2 represents a significant advancement in protecting these sophisticated AI systems from novel vulnerabilities specific to agentic AI architectures. This tool is crucial for ensuring OWASP agentic AI security.

Agentic AI refers to autonomous systems powered by large language models that interact with external tools via the Model Context Protocol (MCP), enabling actions like API calls, data access, and code execution. This capability introduces unprecedented security challenges that require specialized assessment tools. The OWASP-Agentic-MCP 1.0.2 is an open-source security assessment tool developed by MEOK AI Labs to evaluate AI agents against the OWASP Top 10 for Agentic AI, released in 2025.

The tool addresses critical vulnerabilities including prompt injection attacks, tool poisoning, supply chain compromises, and data leakage. With the proliferation of agentic AI systems expected in 2026, understanding and implementing these security measures has become essential for organizations deploying AI agents in production environments.

Understanding Agentic AI and Its Security Challenges

Agentic AI systems represent a fundamental shift in how artificial intelligence operates. Unlike traditional AI models that process input and generate output, agentic AI systems can autonomously decide which tools to use, when to use them, and how to interpret the results. This autonomy, while powerful, introduces a complex attack surface that ex

tends beyond the AI model itself to include all integrated tools and data sources.

The Model Context Protocol (MCP) serves as the bridge between AI agents and external tools. MCP enables seamless integration with APIs, databases, code execution environments, and other services. However, this integration capability creates new vulnerabilities. As the OWASP Foundation notes in their GenAI Security Project, "As AI systems begin interacting with live tools and data via MCP, new security risks emerge that traditional approaches can't fully address."

The risks are not theoretical. Real-world incidents demonstrate the urgency of securing agentic AI systems. Security researchers have identified 126 malicious packages registered under names that AI assistants hallucinate, a phenomenon known as slopsquatting. These packages exploit the tendency of AI systems to generate plausible-sounding package names that don't actually exist, creating opportunities for supply chain attacks. Research indicates that this trend is growing, highlighting the need for robust security measures. [Source: Koi.ai OWASP Guide]

Key Features and Capabilities of OWASP-Agentic-MCP 1.0.2

The OWASP-Agentic-MCP 1.0.2 provides comprehensive security assessment capabilities specifically designed for agentic AI systems. The tool's primary features include:

Full Agent Security Scans

The tool performs comprehensive evaluations of AI agent configurations, identifying potential vulnerabilities across the entire agent architecture. These scans examine how agents are configured, what tools they have access to, and how they handle user inputs and external data. This holistic approach ensures that no aspect of the agent's security posture is overlooked.

Prompt Injection Detection

Prompt injection remains one of the most critical threats to AI systems. The tool identifies vulnerabilities where attackers could manipulate AI agent behavior through carefully crafted inputs. This detection capability helps organizations understand how their agents might be exploited through malicious prompts and implement appropriate mitigations.

Tool Poisoning Checks

Tool poisoning occurs when external tools or MCP servers are compromised or malicious. The tool evaluates the security posture of integrated tools and identifies potential poisoning vectors. This is particularly important given that a single compromised MCP can cascade across an entire environment. The Koi.ai Security Team emphasizes that "A single compromised MCP can cascade across your environment, including risks like rug pulls and typosquatting." [Source: Koi.ai Blog]

Excessive Agency Detection

Some AI agents are granted more permissions and capabilities than necessary for their intended function. The tool identifies instances where agents have excessive access to tools, data, or system resources, helping organizations implement the principle of least privilege. This capability ensures that agents operate with only the minimum permissions required for their specific tasks.

Data Leakage Detection

The tool scans for potential data leakage vulnerabilities where sensitive information might be exposed through agent outputs, logs, or interactions with external tools. This is critical for organizations handling sensitive data that must be protected from unauthorized disclosure.

The tool supports popular agentic AI frameworks including LangGraph and Llama 3, making it compatible with many existing AI agent deployments. This broad framework support ensures that organizations using different technology stacks can benefit from OWASP-aligned security assessments.

Addressing the OWASP Top 10 for Agentic AI

The OWASP-Agentic-MCP 1.0.2 is built specifically to address the 10 critical security risks outlined in the OWASP Agentic AI Top 10. These risks represent a fundamental departure from traditional AI security concerns and emerge specifically because agentic AI systems have autonomy, access to external tools, and the ability to take actions in the real world.

Key risks addressed by the tool include:

ASI01 - Agent Goal Hijack: Attackers manipulate an agent's objectives or goals, causing it to perform unintended actions that benefit the attacker rather than the legitimate user. This represents a fundamental threat to agent autonomy and trustworthiness.
ASI04 - Supply Chain Vulnerabilities: Compromises in the tools, models, or services that an agent depends on can cascade through the entire system. The Koi.ai Security Team emphasizes that "A single compromised MCP can cascade across your environment, including risks like rug pulls and typosquatting."
ASI05 - Unexpected Code Execution: Agents might execute code in unintended ways or with unintended consequences, particularly when interacting with multiple tools or when user inputs are not properly validated.

Traditional security approaches designed for static systems or simple input-output models cannot adequately address these dynamic, runtime-based threats. The OWASP-Agentic-MCP 1.0.2 fills this critical gap by providing assessment capabilities specifically designed for the unique characteristics of agentic AI systems.
