How to Set Up and Use CVE MCP Server
CVE MCP Server is a production-grade security intelligence platform that transforms Claude into a comprehensive vulnerability analyst by exposing 27 tools across 21 data sources including NVD, EPSS, CISA KEV, MITRE ATT&CK, Shodan, VirusTotal, and more. It supports the full security workflow from CVE lookup and exploit discovery to composite risk scoring, IP reputation checks, dependency scanning, and ransomware tracking. Security engineers and DevSecOps teams use it to rapidly triage vulnerabilities, prioritize patching, and investigate suspicious IPs or malware without switching between dozens of separate dashboards.
Prerequisites
- Python 3.9+ with pip and venv support
- Git to clone the repository
- NVD API key (free at nvd.nist.gov) for higher rate limits — 8 tools work without any key
- Optional: GitHub token, VirusTotal key, Shodan key, AbuseIPDB key for full capability
- Claude Desktop or another MCP-compatible client
Clone the repository
Clone the CVE MCP Server repository from GitHub to your local machine.
git clone https://github.com/mukul975/cve-mcp-server.git
cd cve-mcp-serverCreate and activate a virtual environment
Set up an isolated Python environment to avoid dependency conflicts.
python -m venv venv
source venv/bin/activate # Windows: venv\Scripts\activateInstall the package
Install the CVE MCP Server and all its dependencies in editable mode.
pip install -e .Obtain API keys (recommended)
Register for free API keys to unlock the full 27-tool suite. NVD key (nvd.nist.gov) increases rate limits from 5 to 50 requests per 30 seconds. GitHub token raises limits from 60 to 5,000 requests per hour. VirusTotal, Shodan, AbuseIPDB, and GreyNoise all have free community tiers.
Configure Claude Desktop
Add the server to your Claude Desktop configuration file. On macOS the config is at ~/Library/Application Support/Claude/claude_desktop_config.json. Use the absolute path to your cloned repository.

"SHODAN_KEY": "your-shodan-key"
}
}
}
}Restart Claude Desktop and verify
Fully quit and reopen Claude Desktop so it picks up the new MCP server configuration. You should see the CVE MCP tools available in Claude's tool panel.

Sample prompts that exercise the CVE MCP Server's security intelligence tools.
- "Analyze CVE-2021-44228 (Log4Shell) — give me the CVSS score, EPSS exploitation probability, CISA KEV status, and composite risk score"
- "Scan these dependencies for vulnerabilities: requests==2.28.0, django==3.2.0, pillow==9.0.0"
- "Investigate IP 45.33.32.156 — check abuse history, GreyNoise noise status, Shodan open ports, and VirusTotal reputation"
- "List the top 10 trending CVEs this week and prioritize them by exploit availability"
- "Generate an executive risk report for these CVEs: CVE-2024-3094, CVE-2024-21762, CVE-2023-46805"Troubleshooting CVE MCP Server
Claude Desktop shows 'server not found' or the tools don't appear
Verify the 'cwd' path in the config is an absolute path to the cloned repository, and that the virtual environment's Python is being used. Run 'python -m cve_mcp.server' manually in the repo directory to confirm it starts without errors.
NVD requests are throttled or return 403 errors
Without NVD_API_KEY set, you are limited to 5 requests per 30 seconds. Obtain a free API key at nvd.nist.gov/developers/request-an-api-key and add it to the env block in your config.
Some tools return empty results or API errors
Each tool group requires its own API key. Check that the relevant key (e.g. SHODAN_KEY for shodan_host_lookup, VIRUSTOTAL_KEY for virustotal_lookup) is present in the env config. Eight core tools (EPSS, CISA KEV, CWE, NVD) work without any keys.
