How to Set Up and Use Anthropic Cybersecurity Skills
Anthropic Cybersecurity Skills is a community-maintained library of 754 structured cybersecurity skills organized across 26 security domains, mapped to five industry frameworks: MITRE ATT&CK v19.1, NIST CSF 2.0, MITRE ATLAS, MITRE D3FEND, and NIST AI RMF. Each skill encodes practitioner workflows that AI agents can discover and execute for threat hunting, incident response, forensic analysis, cloud security assessment, and penetration testing. It follows the agentskills.io standard and works with Claude Code, GitHub Copilot, Cursor, Gemini CLI, and any MCP-compatible agent without requiring API keys.
Prerequisites
- An MCP-compatible AI agent or CLI tool (Claude Code, Cursor, Cline, GitHub Copilot, Gemini CLI, etc.)
- npx (Node.js 18+) for the recommended install method, or Git for manual clone
- No API keys or external accounts required — the skills library is self-contained
- Optional: Volatility3, network analysis tools, or cloud CLIs if you plan to execute the referenced security workflows
Add the cybersecurity skills to your agent using npx
Use the agentskills CLI to add the Anthropic Cybersecurity Skills library to your AI agent environment in one command.
npx skills add mukul975/Anthropic-Cybersecurity-SkillsAlternatively, clone the repository directly
If you prefer to inspect or modify the skills locally, clone the repo and point your agent at the local directory.
git clone https://github.com/mukul975/Anthropic-Cybersecurity-Skills.git
cd Anthropic-Cybersecurity-SkillsConfigure your MCP client
Add the server to your Claude Desktop or Cursor configuration to expose the skills as callable MCP tools.
Verify the skills are loaded
Ask your AI agent to list available cybersecurity skills or query by framework to confirm the library is accessible.
Execute a skill-driven workflow
Provide a security task to your agent. It will scan the 754 skill frontmatters (~30 tokens), load the top matches, and execute the relevant practitioner workflow.

Example security tasks you can give to an AI agent with the cybersecurity skills library loaded.
- "Analyze this memory dump for signs of credential theft using Volatility3"
- "Walk me through the MITRE ATT&CK T1078 (Valid Accounts) detection workflow"
- "What NIST CSF 2.0 controls apply to lateral movement in cloud environments?"
- "Run an incident response playbook for a suspected Kerberoasting attack"
- "List all D3FEND countermeasures for privilege escalation techniques"
- "Help me assess the security posture of this AWS IAM configuration"Troubleshooting Anthropic Cybersecurity Skills
npx skills add command not found
Ensure Node.js 18+ and npx are installed (`node --version`, `npx --version`). If the skills CLI is not available, fall back to `git clone https://github.com/mukul975/Anthropic-Cybersecurity-Skills.git` and reference the local path in your agent configuration.
Agent returns generic answers instead of framework-mapped skill workflows
Confirm the skills library is correctly added by asking the agent to list skills by MITRE ATT&CK technique. If it cannot, re-run `npx skills add mukul975/Anthropic-Cybersecurity-Skills` and restart the agent session.
Referenced security tools (Volatility3, etc.) are not installed
The skills library describes practitioner workflows but does not install the underlying tools. Install the required tools separately (e.g., `pip install volatility3`) before asking the agent to execute tool-dependent steps.
